Twelve degrees Fahrenheit this morning as I setup the tripod and camera for the third pre-dawn photo shoot of Saturn and Venus. Completely calm, unlike yesterday morning, so no jiggles to the camera, beyond my fumbling numb fingers. I opted for longer exposures (three or four seconds), so I ended up with some trails, especially when using the telephoto lens. Otherwise, much the same as before, with the exception of the planetary dance partners.

I don’t plan on repeating this for a fourth time tomorrow morning, but I do plan on trying to capture the full moon as it approaches Jupiter tomorrow night. There also happens to be a penumbral lunar eclipse occurring Wednesday evening.
Wednesday, November 28
Full Moon arrives at 9:46 a.m. EST. It appears against the background stars of Taurus the Bull before dawn this morning, approximately midway between the Pleiades and Hyades star clusters and below brilliant Jupiter. (The Moon will slide within 1° of the planet after sunset tonight.) But the Moon has a lot more going for it today. First, it passes through the outer part of Earth’s shadow. This penumbral lunar eclipse will slightly darken the Moon’s northern half. People in much of North America can see the eclipse’s early stages, which begin at 7:15 a.m. EST. (Those in Australia, eastern Asia, and the Pacific islands have the best views of the event.) Second, this Full Moon is the smallest (29.4′ in diameter) of 2012. Our satellite’s relatively diminutive size arises because it reaches the farthest point in its orbit around Earth at 2:37 p.m. EST today, when it lies 252,501 miles (406,362 kilometers) from Earth’s center.

I went to bed Sunday night lamenting the end of my longest vacation in over a decade. I double-checked and triple-checked my return-to-work checklist (security badge, laptop, cell phone, sunglasses, lunch bag, work clothes and shoes, etc.) before nodding off. I woke up fifteen minutes before my alarm went off at five o’clock. I jumped out of bed and had myself dressed and ready to go before half past five. I wanted to make sure I didn’t miss this morning’s Saturn-Venus photo opportunity.
I got everything, including the camera and tripod, packed into the back of the van and drove up the hill, squinting through the frosty windshield, to the library parking lot. I left the van running with the defroster on half-blast, but turned off the headlights. I setup the tripod and camera on the sidewalk, but quickly became concerned by the slight breeze from the north, which could (and did) jiggle the camera during the longer exposures necessitated by the pre-dawn darkness.
I changed lenses on the camera back to my normal lens and took a couple of wide angle shots to begin with:
I adjusted the brightness (something I rarely do since I don’t own Photoshop and need to learn how to use Gimp) to make the horizon a bit more visible.
Shortly after six o’clock, I observed Mercury and took a photo in portrait orientation (vertical) to include all three planets and the star Spica:
Because I needed to begin the commute to work at a quarter past six, I had to stop taking photos early. A good thing, too, since my batteries, which I had just put in before yesterday morning’s photo session, had already depleted due to the cold temperatures and long exposure times. I did take the time to switch back to my telephoto lens to zoom in on several of the prime targets.
I managed to snatch a closeup of Venus and Saturn and of Mercury and Alpha Librae before I packed up the equipment and left for work:

Tomorrow morning, weather permitting clear skies, I will attempt to capture Saturn as it slips past and above Venus.
I learned last night at the November general meeting of the Astronomical Society of Kansas City that we have just fifty days (forty-nine as I write this blog) until the end of a Mayan age (the 13th Bak’tun). More commonly known to us as the Winter Solstice on December 21, 2012 (12/21/12 or 21/12/12 depending on your longitude). I had a lot on my mind as I drifted off to sleep last night, but when I woke to clear skies and a newly risen Venus blinking at me through the bare branches of trees along my eastern horizon, I shook off the last vestiges of ancient doom and gloom and braved the brisk late fall pre-dawn environs with my tripod and camera.
Armed with new tips and techniques garnered from Tom Martinez’s astrophotography presentation during the club’s Astro 101 session, I attempted a long exposure (ten seconds long) of the Big Dipper using my normal lens:
I was gratified to discover that my camera can take even longer exposures without the necessity of a handheld remote. Not that I don’t plan to purchase a remote for it soon though.
I didn’t attempt to capture Canis Major or Orion in a long exposure since I would have been shooting west over the well-lit parking lot of City Hall. Instead, I turned my camera towards the southeast and bright shining Venus and the slightly dimmer Saturn.

I knew Mercury had risen shortly after six o’clock, but I couldn’t see it clearly until about a quarter after.
Mercury & Alpha Librae in a four second long exposure.
Later, I accidentally captured not only Mercury, but a passing plane, as it took off from KCI (northeast of my location).
Passing Plane (the streak) approaching Mercury
When I got back to my laptop and downloaded the photos, I also double-checked and compared them to the alignment at the time they were taken using the Star Dome Plus java applet at Astronomy.com: A short successful photo shoot this morning. I didn’t hang around for the sunrise, since I judged it wouldn’t be as pretty as the one I captured Saturday morning.
Weather permitting, I’ll be repeating this activity for the next two or three mornings. I’m excited to see Venus and Saturn pass each other in the night (or very early morning).
And next week I’m going to wish I was visiting Egypt to witness a once in 2,737 years event involving these same three planets and the Great Pyramids at Giza.
The new moon occurs tomorrow just eight minute’s past four o’clock in the afternoon. I reviewed the sun rise and moon rise times for today, tomorrow and the next day as compared to the time the new moon happens. And, once again, the ‘holy grail’ of observing a moon less than one day from dying or one day new-born eludes me. Tomorrow morning, on the 13th of November, 2012, moon rise occurs at 6:41 a.m. Central, just twenty minutes before the sun rises. If that wasn’t ‘bad’ enough, I’ll be driving the van for the Tuesday commute to work at that time. My final rider pickup occurs at that time, so I may be able to take a couple of minutes with my binoculars to see if I can see the almost dead moon about eight hours before it is reborn as the new moon. I don’t have high hopes though, as twenty minutes before sun rise is quite bright and the eastern horizon will be hazy unless I’m extremely lucky. And the chance of catching any sign of the extremely young moon (less than an hour old by sun set tomorrow night) is even slimmer than the crescent moon would appear at that time.

I woke up knowing the temperatures had plummeted to the lower 20s overnight, leaving the sky crystal clear and killing the wind we’ve had for the past week. Since my kitchen is completely unusable for the next week or so, I decided to pack up the van for the Monday commute, start it up (since frost completely covered all the windows) and gather up my camera equipment for an pre-dawn frigid photo shoot of the nearly dead moon.
I drove the still cold and nearly empty van up the hill to the dead-end in front of City Hall. I left the van running to continue the process of thawing out the windows and doors while I took the tripod and camera a few feet back up the hill to the east side lawn of City Hall. I could barely see the new risen moon through the leafless trees lining the south and southeastern horizon. I found a spot where the moon just clear the tree limbs and setup the camera equipment. I took my first photo at 5:47 a.m., about nineteen minutes after the moon rose (at 5:28 a.m.). I tried various settings and exposures, while trying to keep my hands warm and not shake the camera too much. I took several unsatisfactory photos for about ten minutes and then returned to the van. I needed to fill up the gas tank and get something warm to drink before heading south to pickup my first setup of riders. My local rider had the day off because he’s a federal employee and today is the day set aside to observe and honor our veterans.

After filling up the van, I drove back up the hill so I could cross Main Street using the light between City Hall and the Library and just happened to look east again. I noticed the colors caused by twilight and pulled into the Library’s parking lot for a second photo shoot. I quickly reset up the camera and took another ten minutes worth of photos before continuing on to Scooters for a warm mocha and a caramel apple scone.
Venus, Saturn, Spica and the Waning Moon
I downloaded the photos from the camera and reviewed them. I threw away most of the first photo shoot because I forget to set the two second delay timer and most of them were blurry. I logged into my Astronomy.com account and downloaded the sky dome for the east-southeastern horizon to confirm and label the objects photographed above.
I had completely forgotten that Saturn had finally come out from behind the sun to become visible once again in the early morning. In fact, Saturn rose just nine minutes after the moon did, although my camera did not capture it in my first photo shoot, probably because it was hiding behind some tree limbs.
I also photographed the Big Dipper, Orion, Canis Major and the Pleiades, but decided not to share the photos with anyone yet. Because I didn’t change from my telephoto lens to my normal one, I did not get all the stars in the handle of the Big Dipper nor did I capture all of the stars in Orion.
I’ll probably miss this weekend’s meteor shower, as I will be otherwise occupied during the day and not in a location that will provided dark enough skies to properly observe a shower. A solar eclipse occurs tomorrow, but only for those excessively lucky people who live in the South Pacific. For more of what’s up this week, visit Astronomy’s the Sky this Week website.
I put an appointment on my calendar earlier this week with an alert to remind me to go chasing planets after sunset on Tuesday evening. I make sure to check Astronomy and Sky & Telescope magazines’ websites for their ‘The Sky This Week’ observing articles and place the interesting (and observable from my location) items on my calendar. Here’s the paragraph for Tuesday evening from Astronomy’s web site:
Tuesday, August 21 – Our trio of bright evening objects — Saturn, Mars, and Spica — forms a pretty equilateral triangle (5° on a side) in the southwestern sky after sunset. But the highlight of the scene tonight is a gorgeous crescent Moon that hangs just 4° below Mars. Binoculars provide the best view of this celestial gathering. Look closely and you’ll notice the objects’ different colors. The Moon’s color depends largely on conditions in Earth’s atmosphere and could be anywhere from white (under a dry, haze-free sky) to yellow or even slightly orange. Sunlight reflecting off Saturn’s clouds has a golden glow while Mars’ ruddy deserts cast an orange hue. Blue-white Spica generates its own light from a scorching surface nearly four times hotter than the Sun’s.

Terry and Sean had retreated to the band room for rehearsal and I sat slogging my way through the 49th Parallel, a British WWII film released in the United States under the title The Invaders. I recorded it a couple of weeks ago off the TCM channel. It drags and I still haven’t finished it. So when my phone buzzed with the text message alert, I jumped, literally, at the chance to stop watching the film and start looking up at the sky.
I took my camera gear and got in the van. I couldn’t take the Bonneville because Sean’s car happened to be parked in front of the garage. I didn’t mind taking the van; it’s what I drive every weekday anyway. I left the house at 8:20, about fifteen minutes after sunset, so the western sky still shown with twilight. I could clearly see the bright waxing crescent moon, but could not yet see Saturn, Mars or Spica. I drove west and southwest from Lansing, trying to find a spot clear of trees on top of a hill to setup the camera.
I ended up driving almost an hour all over the middle of Leavenworth County and even through the small unincorporated town of Jarblo. I never did find a satisfactory location. I finally stopped in the parking lot of the High Prairie Church at the corner of 187th street and the end of Eisenhower Road. The church had blazing bright lights illuminating their building, but I parked far away at the north end of the parking lot and used the van as a shield. I took several photos with various settings for about ten to fifteen minutes. I took a few minutes to just look around at the night sky from this location, liking the clear 360 degree visibility (lack of trees and less light pollution, if you didn’t look towards the church building). I could clearly see the constellations Scorpius, Sagittarius, Cassiopeia, Ursa Major, but still only about half the stars in Ursa Minor. I could not yet see Pegasus as it still needed another hour or two to rise out of the east.
I packed up the camera gear and headed home, using Eisenhower Road to get back to Lansing. I parked the van, noting that Sean’s car still sat in the driveway. I returned to the living room, unpaused the 49th Parallel and again attempted to finish the film. Within five minutes, Terry and Sean came upstairs and Sean said his goodbyes. I asked Terry if he had even noticed that I’d been gone for an hour. He had that ‘deer in the headlights’ look that answered my question well enough.
I stopped my feeble attempt to finish the movie and instead switched to the season premiere of Top Gear, an episode featuring a battle between the three big American auto makers to produce a successor to the reigning but retiring police vehicle of choice: the Ford Crown Victoria. The Stig, driving a minivan, managed to evade all three Crown Vics, shaming the hosts (and the cars they were driving). That initial segment ended in a free-for-all demolition derby of the retiring behemoths. I made sure to Tweet the abuse to a friend who still owns (and loves) his Crown Victoria.
By the time we finished watching Top Gear, I realized I was up way past my bedtime. I retreated upstairs and crashed.

I hit the snooze button a couple of times this morning, not happy at all with the shortened sleep. I made a strong pot of Irish Blend tea to take with me during the morning commute so I wouldn’t nod off and disrupt my riders with an accident or off-road excursion. I did remember to grab my camera’s memory card so I could download and review the photos I’d taken the previous evening.

I re-read the paragraph on the Astronomy.com web page and decided to test the equilateral triangle theory on my photos of Mars-Saturn-Spica. I used a nice clear plastic ruler to measure, on my laptop screen, the distance in centimeters between the three corners of the triangle. The distance between Saturn and Spica and Saturn and Mars appeared to be identical. But the distance between Mars and Spica was greater by 1.5 to 2 centimeters. So, technically, my photo did not confirm the observation of an imaginary equilateral triangle. Perhaps earlier in the day (or even the previous day), Mars might have been in the exact position to be equidistant visually from Saturn and Spica, but not last night at a quarter past nine o’clock.
I still hope to net Neptune this weekend, but my chances are looking slim. The weather forecast for the next few days includes thunderstorms. Ironic, that, since my next night to volunteer at Powell Observatory is this coming Saturday. This would be my third night of the public season, and if overcast, would make it two out of three times cloudy.
Friday evening I had my first opportunity to really dig in and learn about the telescope I borrowed from my astronomy club. A week ago, Terry and I returned to Kansas City to meet one of the club members at the Warko observatory on the roof of Royall Hall on campus at UMKC. I put in a request to borrow an eight inch Dobsonian telescope (shown at left) to compare and contrast its light gathering abilities with my own ETX-90 (a Maksutov-Cassegrain type telescope). I had high hopes since the aperture on the XT8 is more than twice as big. On the other hand, the ETX-90 is lighter. I drove the van, having hidden the middle set of seats in the subfloor, to make the initial transport of the telescope as easy as possible.
Fast forward an entire week to another Friday evening. After a quick rather disappointing dinner at the local Dairy Queen, Terry and I returned home to separate activities: he to a strings-only practice for one of his bands and me to setting up the loaner scope.
Orion SkyQuest XT8 base
I moved the base into the great room (so called because it’s the biggest room in the house and has a high vaulted ceiling with a floor-to-ceiling corner fireplace). I then re-read the instruction manual, paying close attention to the section dealing with placing the optical tube on the base. The tube weighs just a bit over twenty pounds (the base is a couple of pounds heavier). I picked up the tube, holding it vertically, and rested it gingerly on the bumper stops. I inserted the tension and retaining knobs per the directions and then tested the altitude and azimuth mobility. The base seemed to stick a bit, but nothing that couldn’t be overcome with some nudging.
I attached the finderscope to the optical tube, but did not attempt to adjust it until later, when the tube would be outside and I could find an object to orient on a suitable distance away from my site. I removed the dust cover cap for the tube and for the eyepiece in anticipation for the next phase: collimation
When the mirrors are properly aligned, the view down the focuser drawtube should look like the graphic above (for the XT8 telescope).
I peered down the optical tube, past the secondary mirror and its spider support system at the large eight inch mirror nestled in the bottom. A small faint circle was inscribed on the surface of the mirror, assumedly in the exact center. I stepped around to the side of the tube and stared down through the eyepiece opening, where I could clearly see my own eye and the small circle mentioned above. My pupil and the circle did not line up exactly, as they should have (see diagram above left).
Upon further reading, and searching through the boxes and bags that the telescope came in, I could not find the collimation cap referenced in the instruction manual: “This cap is a simple cap that fits on the focuser drawtube like a dust cap, but has a hole in the center and a reflective inner surface. The cap helps center your eye so that collimation is easier to perform.” I forged ahead, hoping I could get the mirror aligned ‘close enough’ for some test observing later that night.
I followed the instructions carefully, reading and re-reading and comparing what I was seeing through the focuser drawtube with the examples provided in the manual. I decided the secondary mirror didn’t need any adjustments, just the primary mirror. The locking thumbscrews on the back of the mirror were already loosened, so I began experimenting with small turns of the larger thumbscrews to adjust the tilt of the primary mirror. I eventually got the small circle in the middle and tightened the locking thumbscrews down. Now to move the unit outside to align the finderscope.
I tilted the tub vertical, grasped the convenient handle on the back of the base with my right hand, keeping the tube vertical with my lefthand. I walked slowly out the back door on the patio and down to the lower level of my back yard, away from (as much as that is possible) the surrounding trees (mine and my neighbors). I needed to find an object about a quarter of a mile away to align the finderscope. Because I live in a valley (Fawn Valley to be precise), everything, including the ground, is up from my backyard, and most of the horizon is blocked by houses and trees. I could barely see the road leading up the hill to where City Hall stands, a couple of blocks to my south. That would have to do. I quickly and easily got the finderscope dialed in.
Now, I had to wait for darkness to fall. I brought out my eyepieces (the three that came with the scope I left in the box with the solar filter) so they and the scope could reach a temperature equilibrium with the outside environment. I went back inside and reviewed the Astro Quest observing award object list and my sky atlas to determine a short list of objects to observe before the moon rose high enough to wash out the night sky.
At half past nine, I went back outside, knowing I’d be able to find Saturn and Mars in the southwestern sky. I did and quickly tried nearly every eyepiece I had, from a 30 mm down to a 9 or a 4 mm. I doubled a couple of those using a 2x barlowe lens. I could clearly see the Cassini division in the rings, but did not try to discern any cloud variances on Saturn’s surface.
I pointed the scope at Mars next, but again, while a bright ruddy object, the red planet still seemed just the size of a pinhead, no matter how much magnification I attempted to throw at it. I guess I need to ask some club members for assistance with seeing well enough to find the polar ice caps. Perhaps I’m just too late in the year, since Mars now sets an hour or two after sunset and I’m looking through so much thick, dirty, hazy, humid air.
I could tell the moon had risen, but still remained low in the east, hidden behind houses and my tall pin oak in my front side yard. My observing goals for the evening included three multiple star systems. The first one I had actually observed when I first got the ETX-90 back in October 2010. The middle star of the handle of the Big Dipper is actually an optical double star, Mizar-Alcor. Terry joined me in observing this popular duo.
My second observing goal could be found in the constellation Lyra, containing the brightest star in the summer sky, Vega, and one of the three stars that form the asterism commonly referred to as the Summer Triangle. Finding Vega turned out to be easy. Correctly adjusting the movement of the telescope when aimed directly overhead, not so easy. I had to run back inside to find my red flashlight and grab my reading classes and sky atlas before attempting to star hop the very short distance from Vega to Epsilon Lyrae, also known as the Double Double. In hindsight, I also had forgotten to confirm how many degrees field of view the finderscope provided me (five degrees from the spec page of the instruction manual read this morning). Because of the light pollution around my house and the rising nearly full moon, I could only see Vega and the beta and gamma stars of Lyra. I could clearly see a triangle in the finderscope with one of the three stars Vega for sure, but which one was the Double Double? I may have observed it last night, but I’m not entirely sure. I plan to retry tonight, provided the predicted thunderstorm activity fades before ten o’clock or soon after.
Albireo (courtesy Wikipedia)
My final observing objective also appeared almost directly overhead, this time in the constellation Cygnus. The head of the swan (Beta Cygni also known as Albiero) is a striking colorful double star that I easily found and observed for a few minutes. Terry also took a quick look, but opted to let the mosquitoes and chiggers feast on me instead of him. Since the moon would soon escape the defense put up by my pin oak, I asked Terry to help me carry the telescope back into the house while I held the red flashlight overhead to light our path.
I put all the eyepieces back in their cases and all the dust caps on all the openings of the telescope. I recorded two of my three observations on my Astro Quest sheets. Terry, Apollo, Lexy and I all retired to bed and left the moon to play by itself through the short summer night.
Some pros and cons about the Dobsonian telescope: I like the improved light gathering capabilities. I love the finderscope (it’s a very good quality one), but would love it more if it had a right-angle viewer. I did not like the height of the eyepiece on the side of the tube. I will need to get a portable stool to lean against. My back is still aching this morning from the constant bent over position I found myself in last night.
Overall, I enjoyed my first foray among the stars with the SkyQuest. I did not use the Intelliscope handheld device that would have assisted in identifying and locating objects. I will save that adventure for another night, possibly at a darker site.
Saturday evening I headed south to Louisburg to volunteer for my second scheduled night of the 2012 Powell Observatory public season. My dad decided to tag along, to enjoy the show and help keep me awake for the long drive home. We left Lansing about twenty minutes after five and my car’s external thermometer reported 106 to 107 degrees, which has been our afternoon average for about a week now, give or take two or three degrees either way. We stopped in Bonner Springs to grab a quick, cool sandwich from Subway and returned to the highway just shortly after six o’clock. I needed to be at Powell Observatory by seven o’clock to help prepare the facility for the weekly public program and observing night.
As we approached Louisburg from the north, I noticed a definite increase in the wind, so much so that my car was jostled several times. At the same time, I noticed a significant drop in the external temperature. By the time I exited US-69, the thermometer read 92 degrees, and was still falling. Except for early mornings the past couple of weeks, I had not seen or felt such low temperatures while the sun still shone. I pulled into the west observing field parking area and realized I was again the first person to arrive. Since the temperature had dropped, I turned off the car and opened all the windows. The breeze felt incredibly refreshing.
My team leader arrived within a few minutes and I received my Powell Observatory ‘Staff’ T-shirt, which I changed into as soon as the building was unlocked. I helped setup the class room for the program, ‘Sounds of Space.’ Another ASKC member arrived and setup his ten-inch Dobsonian for solar observing and I caught a glimpse of some great sunspots before our public guests began arriving. The clouds provided some dramatic solar observing situations.

I repeated my role as gatekeeper and accepted donations from the public and queried them for their ZIP codes to record for future grant petitions. The first group of twenty-five guests began the ‘Sounds of Space’ program at 8:30 p.m., but I soon had at least that many waiting for the second showing. At one point as I sat waiting for more guests to arrive, what I thought was a stray dog wandered into the observing field, soon followed by three horses, two with riders and a third colt between them. They trotted across the field to the west, with the dog trailing after, riding off into the sunset … literally.
Constellation Scorpius
As the sky continued to darken, despite a few wispy clouds, we opened the dome so those waiting for the next program could observe Saturn and a globular cluster found in the constellation Scorpius. I didn’t get a chance to look at the cluster through the 30-inch scope, but I believe they looked at M4, which is near the bright star Antares.
We ended up having nearly ninety public guests Saturday evening and ran a third showing of our program. After the last two guests had left the dome a bit after eleven o’clock, I quickly snuck a peak at the Ring Nebula in the constellation Lyra, one of the Messier Objects I’ve been trying go get a glimpse of for quite some time. Lyra is also home to the very bright star Vega, one of the three stars that form the Summer Triangle.
As the final guests drove away, my team members and I began cleaning the building and storing chairs, tables and other items for the next Saturday. I signed myself out of the Observatory at 11:35 and gathered up my dad for the long drive home. He related information he’d gleaned from another team members about various types of Dobsonian telescopes and helped keep me alert as we sped north towards Leavenworth County.
Next week, we present a program on ‘Our Amazing Moon’ and the following week we’ll pose the question ‘Is There Life Out There?’ We look forward to showing you the astronomical sights (and sounds).
John Reed leads a workshop on widefield astrophotography with a DSLR at MSRAL (Sun 03 Jun 2012)
After a handulf of hours sleeping, I drug myself out of bed early Sundy morning. Rather than eating breakfast, I composed my blog post recapping Saturday at the MSRAL convention. I published at ten after eight o’clock, leaving me less than an hour to drive to UMKC from Lansing. The last day of the convention consisted of a morning dedicated to three workshops. Not knowing what I might need, I packed up my laptop and my DSLR camera and zipped down I-70, arriving with about ten minutes to spare.
I burdened myself with my laptop bag, camera backpack, purse and water bottle and trudged up the stairs to the Student Union. I opted not to take the additional four flights of stairs on the interior of the building, taking full advantage of the elevator to the top floor. I planted myself on the first row (as I’ve done each day of the convention) so I wouldn’t have any trouble hearing or seeing (or taking photographs like the one above).
First Workshop: Widefield Astrophotography with a DSLR by John Reed
Very interesting workshop on using consumer camera equipment (a Canon DSLR and a 200 mm telephoto with an AstroTrac mount) and some post-production work with Photoshop for stunning astrophotography.
Second Workshop: Variable Star Research with Modern Amateur Equipment by Jim Roe
The middle workshop presented by Jim Roe dealt with variable stars and doing some hands on scientific observation and research. I got to know his old friend Z Umi (a variable star in the Little Dipper).
Third Workshop: Successful Web Cam Astronomy by David Kolb
David Kolb answering questions after his Successful Web Cam Astronomy workshop at MSRAL (Sun 03 Jun 2012)
The final workshop of the day got really hands on, for those who wanted to participate in the step-by-step process of massaging web cam videos taken of Saturn to produce a nice crisp stacked image. The entire presentation will be uploaded to David’s website (Sunflower Astronomy) in the near future.
Final Musings on the Convention
I learned so much and met some great people. I have many fascinating ideas and concepts revolving through my brain and many new projects I’m inspired to pursue. I look forward to attending similar conferences when they pass through the area again.
Even though Friday dawned overcast and gloomy, by noon, I could see bits of blue among the dissolving puffs of grey and white. I received an early confirmation e-mail from ASKC announcing the ‘go live’ time for the astronomy club’s star party at Powell Observatory in Louisburg, Kansas. I had already invited Dad to come as my guest and not only because Terry already had plans. The weather forecast predicted clear skies, but cold temperatures, reaching mid-40s by midnight on the observing field.
I left work at the usual time and retrieved all my riders, returning them safely home without delay. Not even the race activities at the Kansas Speedway slowed me down when I dropped off my first rider, who lives within spitting distance of that facility. We all could hear the cars racing around the track, not for a race, but more likely for practice or qualifying.
I got home and realized I had forgotten to print a map with directions from Lansing to Louisburg and wrangled Terry into printing one for me. While I was waiting on the printout, my Dad arrived, bringing me a beautiful rose from his garden. He placed it smack dab in the center of my table, but I didn’t notice it until I knocked over the vase with my camera bag. Then, I mistakenly thought Terry had stolen a rose from one of our neighbors. Dad had a hard time not laughing himself silly, especially since he tried to let Terry take the credit for the impromptu flower appearance. I thanked Dad for the gift while I mopped up the spilled water with a spare towel.
I changed clothes, grabbed a sweater with a hood, my scarf, my gloves, a gallon of water, my water bottle, my camera bag and tripod and my purse. Dad already had the rest of the gear in his trunk. We rolled south out of Lansing by a quarter to six. We stopped briefly in Bonner Springs for a quick supper and continued down K-7 to Shawnee Mission Parkway, then to I-435 and eventually US-69. Louisburg is less than twenty miles south of Overland Park, so once we rounding the curve where I-35 crosses I-435 (where the mile markers for I-435 start at zero (0) and end at eight-three (3), we had less than a half hour of driving to reach the observatory. We pulled into the park just a bit after seven o’clock in the evening.
The star party organizer for the ASKC was already on site. He greeted us and we all began debating where to setup on the observing field around Powell. He was concerned about a baseball game or practice that appeared to be occurring on a ball field just northwest of the site. He drove over and asked the participants if they planned to turn on the field lights. He returned to confirm the lights would be on until 9:30 p.m. Thus, all of us decided to setup on the east side of the Powell Observatory building, letting it block the lights to help protect our night vision.
Dad and I unpacked the gear and hauled it across the observing field to a spot just southeast of the dome. I setup my camera and tripod to take a couple of photos of the sunset.
As predicted, the lights lit up the field, and competed with the glow of Kansas City sufficing the northern horizon. Dad and I waited patiently (him more than me) for enough stars to pop forth to attempt an alignment of the telescope. While we waited, I took a few more photos of the western horizon, mostly to capture the very bright Venus.
Soon after we spotted Venus, Sirius made its appearance in the southwestern sky. Once Arcturus crested over the trees in the northeast, we used both those stars for an alignment of the ETX-90 via the Autostar device. We did a quick tour of the four visible planets, starting with Venus. Even though Venus is a thinning crescent (as it moves towards us and between the Earth and the Sun), it is almost too bright to look at. Without adding a filter to the eyepiece, I couldn’t look directly at it for more than a few seconds. Next we caught Jupiter before it set in the west. I spotted all four moons, but only for the first few minutes. As it sunk closer and closer to the horizon, the haze and humidity obscured all but the planet itself from visibility.
Next we swung the telescope back to the southeast, but nearly directly overhead (about ten or eleven o’clock above us) to view Mars. While I debated internally what higher magnification eyepiece to insert, the star party organizer joined Dad and I at our telescope. He commented that he had owned a similar scope in years past and affirmed it was a good scope for planetary and lunar observing. He took a quick look through the eyepiece at Mars and moved on to the next person on the field. One of my goals for the evening was to decide if the small ETX-90 would allow me to view any deep sky objects (galaxies in particular).
Our final planetary tour stop landed on Saturn, which crested over the trees soon after we finished observing Mars. I easily found Titan, Saturn’s largest moon, but could not discern the gap(s) between the rings, even after adding the two times Barlow to the 25mm eyepiece I prefer to use.
Orion had his left foot on the western horizon as I swung the scope back to the southwest for a quick peak at the Great Orion Nebula. As far as I could tell, it looked similar to what I had seen from my back yard in late March. At that time, Orion’s Sword appeared much higher in the sky and I looked through less atmosphere (but had more light pollution in Lansing). But the combination of less light, yet more atmosphere gave me basically the same observing experience.
Ursa Major (aka the Big Dipper)
At this point, I took a break to spare my aching feet and sat in one of the chairs Dad had brought along. The north wind had died off by this time, but I couldn’t seem to get my toes enough circulation. The rest of me, my head, hands, upper body and legs, were fine. But my toes continued to be a distraction and eventually a source of chilling pain. I used my red flashlight to review several star charts in my pocket sky atlas, searching for a deep sky object that would be (hopefully) visible via my small scope. I settled on the Whirlpool Galaxy found near the first star (Alkaid) in the handle of the Big Dipper. As you can see in the chart above, just below and to the right of Alkaid is where you should find the Whirlpool Galaxy. Even with a red dot viewfinder to help, neither Dad nor I could locate the galaxy. It only has a magnitude of 8.4, and I fear the increasing glow from Kansas City to our north and the rising humidity as the temperature dropped to the dew point conspired against our efforts.

Before I could pick up my pocket sky atlas to find some other deep sky object to try, the star party organizer returned, asking us if we wanted to see the Leo Triplet, three galaxies visible all at the same time. While not as clear as the photo at the left, I did see all three galaxies through his telescope in one field of view. Amazing! Once I returned to my scope, I directed it to find Mars (which still hovers near Leo) to confirm the alignment and then told it to find M65 (one of the two galaxies on the right hand side of the photo above. I believe I saw a grey smudge or two, but not the third fainter elongated galaxy (on the left above). Since Leo still appeared directly overhead, and Louisburg to the southeast does not sport nearly as much light as Kansas City to the north, I had good conditions for seeing such faint objects (magnitude 9 and 10).
At this point, I could barely stand on my aching chilled feet any longer. I sat for a few minutes, letting my eyes wonder around the sky in hopes of seeing a few meteors. I did see two. I asked Dad if there was anything else he wanted to observe. I think he returned to Saturn for a final look at the ringed giant. After that, we dismantled the equipment and packed it back up (all in the dark with a dying red flash light). We made several trips across the observing field to the car.
As Dad started up the car (and I turned the heat for the passenger side all the way up to red hot), the clock on the dash flashed 11:00 p.m. We pulled out of the parking lot with only our parking lights on (to minimize light for those still observing) and stopped at McDonalds so I could buy a mocha. All three convenience stores in Louisburg had closed (not extremely convenient for us obviously). We retraced our route up US-69, through Overland Park, to I-435 and took Parallel Parkway back to K-7 and arrived back in Lansing just after midnight.
After this excursion, I believe I need to start saving my pennies for an upgrade. I still plan to use the ETX-90 to observe the Transit of Venus. The small scope is actually a boon for observing our closest star, Sol and our sister planet, Venus. I just need the solar filter film, currently on back order, to prevent damage to my eyes and the scope.
I valiantly kept myself awake past my pumpkin transformation time (usually half past nine o’clock on weeknights), reading an ebook on my Nook Color while Terry dozed through the UFC fights. When I finally got within twenty pages of the end of my book, I put the ereader aside and checked the position of Mars from my front porch. The waxing moon hung at about the one o’clock position in the sky almost hidden behind my house and Mars shown redly at about the ten o’clock position. I decided to setup the telescope in my driveway, even though all the street lights and house lights concentrated their glows more intensely on the east side of my property.
I opened the garage door and began transferring the telescope and accessories from the band room (behind the garage on the west side of the house) through the garage to the driveway. I had put on a sweater but only had flip-flops on my feet (something I would come to regret an hour or so later).
In setting up my telescope, I made an error in the home position and failed two attempts at an easy alignment. When I finally realized my mistake, after having run the motors up to and beyond the stops twice, I tried a third time, but the Autostar control device disconnected itself from the telescope and reset itself twice. I gave up and finally just pointed the scope at Mars, shining brightly and sanguinely from the constellation Leo.
Two of the stars selected by the Autostar alignment program included Sirius, in the constellation Canis Major, and Capella, in the constellation Auriga, and both of these stars could be found in the Winter Circle. The waxing moon enjoyed center-stage in the Winter Circle on a cold clear late winter night.
Once I got Mars in my sights, I tried various barlows and eyepieces, but could never quite get a good focus on it. I could dimly and vaguely see the polar ice cap and Mars definitely had an orange-ish and pink-ish cast to it.
By this time, I could barely feel my toes, but I didn’t want to stop observing, so I turned the telescope farther eastward, looking for Saturn. I found Spica in the constellation Virgo. Saturn is just a short hop to the left of Spica. I clearly saw the rings, but did not take the time to look for Titan or any of Saturn’s other moons. I wanted to get my feet warmed up, so I shutdown the telescope, packed everything up and transported it back to the band room.
I may repeat this entire process tonight, but from a different location. I will take a nap this afternoon to allow me to stay up past my pumpkin transformation point.
Oh, and I did get my feet warmed back up while finishing the last twenty pages of my ebook.
