Fishing for Neptune: Testing the Waters

I couldn’t wait for midnight Friday night.  The forecast for the weekend seemed unbelievable, especially after the scorching heat of the last month.  Clear skies and mid to lower 80s for the high temperatures over the next several days.  I came home from work to a grilled steak and baked potato dinner, prepared by Terry.  Mmm-mmm good.

After dinner, Terry and I began reviewing the DVR play list and guide, deciding to delete many old recordings to free up some disc space.  Our daughter called and chatted with us for about forty-five minutes.  The conversation ended abruptly when her phone battery died.

For dessert, Terry blended a frozen raspberry lemonade.  I read for a few minutes, while slowly sipping the drink (trying to avoid a brain freeze).  I asked him to wake me up around midnight so I could scout the skies in search of the Andromeda galaxy and the planet Neptune. Apollo followed me upstairs to the bedroom to join me in my nap.

Terry woke me up just shortly after midnight.  I rubbed the sleep out of my eyes and found my flip flops.  I followed Terry back downstairs to the band room and walked out the patio door to the back yard.  The skies were clear, if not what you’d call dark (why do my neighbors leave their porch lights on all night long?).  I went back inside for one of my star charts and a pair of binoculars.  I didn’t trust myself to lug the telescope outside in the dark, not being completely awake yet.  A survey with the binoculars should be sufficient for my first attempt.

I walked out into my backyard, towards my one remaining pine tree and turned back around to face the east.  What a difference a couple of hours makes!  I could clearly see the Great Square of Pegasus hovering directly over my roof.  In fact, my chimney seemed to be pointing a finger at the famous flying horse.  I remembered what I’d read in the EarthSky post about finding the Andromeda galaxy and put what I’d learned to good use.  With just a pair of mediocre binoculars, I easily found the smudge that is M31.  Now I regretted not moving the XT8 outside before I took my nap.

I turned ninety degrees to the right and began scanning the southern skies.  I can’t see most of the southern horizon, which is blocked by my neighbors tall trees and houses (and all the exterior lighting attached to them).  I lose a good twenty if not thirty degrees of sky in all but one direction, to the southwest I can see a bit of horizon, but only through the even worse light pollution generated by the parking lot of a doctor’s office and the streetlights along Main Street (also known as K-7/US-73).

I needed to find the constellations Aquarius and Capricornus.  The ecliptic passes through both of these constellations.  Neptune swam the night skies somewhere between the two constellations on the invisible ecliptic course all the planets chart.  The trouble in finding Neptune in this area of the sky comes from a lack of bright stars to anchor from for star hopping.  I spent the next hour comparing the star atlas from my pocket guide to the stars I saw through the binoculars and eventually convinced myself I had found the southeastern tip of Capricornus.  Just above those stars, I believe I found the two brightest stars in Aquarius, Sadalmelik and Sadalsuud, but those two stars were too high above the ecliptic and too far away in the field of view of the binoculars to find Neptune.  I needed to do more research and next time use a telescope to help cut through the fog of light pollution.

After an hour, I returned inside and went back to bed, resolved to research better star charts in the morning.

I went back to Astronomy.com and re-read the article on Neptune, but I just couldn’t relate their star chart (shown above) to what I’d observed last night through the binoculars. I would need more magnification and a more steady mount to zoom in and match up the stars shown above to the field of view of the XT8.

I tried Sky and Telescope’s web page and found a better set of charts in a PDF format in their article about Uranus and Neptune visibility during 2012.  I downloaded the document and will print it today to keep with the rest of my star charts.

Saturdays are always packed full of activities, so I’m hoping I’ll still have the energy tonight to make a second attempt at finding Neptune.  My scouting trip showed me what I needed to overcome before I proceed with netting Neptune.

Mercury Rises

I rode a rollercoaster of challenges this past weekend.  On the high side, my son and daughter-in-law drove up from North Texas for a visit.  On the down side, despite the worst drought in recorded history, cloud cover prevented me from observing the Perseid meteor shower Saturday night/Sunday morning and the occultation of Venus by the Moon Monday afternoon.  The Ides of August dawned clear this morning, the first time in nearly a week I’ve been able to see the morning planets and waning crescent moon shining brightly above the eastern horizon.

I only hit the snooze on my alarm once, because I stayed up too late with Dob and then decided to watch the latest episode of Warehouse 13 instead of going to bed like I should have.  My adventures in the backyard with the XT8 and the Intelliscope handheld computer device determined one of the sensors (probably the altitude one) is not reporting to the device as it should.  I’ll have to troubleshoot that situation Thursday evening.  I attempted to star hop from Deneb to the North American nebula, but seeing (visibility) proved too poor and I need more practice with the XT8 so I know which direction I’m going (what I see in the eyepiece v. what I see in the finderscope v. what I see on my star atlas).   

Before the alarm could buzz a second time, I got up, got dressed, grabbed my purse and left the house.  I drove the van a couple of blocks up the hill from my house to the dead end in front of City Hall, where I have a completely unobstructed view of the eastern horizon (I routinely see airplanes take off and land at KCI and can usually see the control tower as well).  I retrieved the camera and tripod from the back of the van and had it setup, with the normal lens attached, just shortly after 5:30 a.m.  I took a few wide field shots to capture all three planets and the moon. 

3 Planets 1 Dying Moon
3 Planets 1 Dying Moon ~ 15 Aug 2012 5:49 am Central

The above photo immediately took me back six months, when I went hunting for Mercury the first time. Last Febriary, I chased after a similar lineup of Jupiter, Venus, the new moon, and Mercury, during the evening hours, looking towards the west. Now, I’m on the flipside, for real.  Warm, instead of cold.  East, instead of west.  Dying moon, instead of newborn moon.  Mercury rising, not falling.

I love seeing Orion rising in the east.  To me, the Hunter heralds the approaching fall, my absolute favorite season of the year.  His two canine pals nipped at his heels (Canis Minor and Canis Major), illustrating we truly are in the ‘Dog Days’ of Summer

I took a few more shots of all three planets in one frame, then zoomed in on Mercury and the Moon, trying to capture that ellusive earthshine.

I ended my photo shoot with several closeups of the waning moon, using my telephoto lens. I selected the best of the bunch to upload to Flickr and share here.

Waning Moon ~ 15 Aug 2012

Next up for me, astronomically, is hunting for Neptune, which reaches peak brightness (opposition from the sun with us in the middle) on August 24th. I will need to wait until close to midnight Friday to make my first foray, when the other blue planet should be visible from my backyard (between tall trees and houses) in the southern skies, swimming in the constellation Aquarius.

Friday Night Lights and Monday Highlights

Waning Moon
Waning Moon approaching Jupiter (Fri Aug 10, ’12)

Very early Friday morning, I caught the waning moon approaching Jupiter and Aldebaran. You could draw a line from Venus to Moon and cross over or near Jupiter.  The skies were clear and should stay clear throughout the day and into the night, with a forecasted high in the mid-80s, twenty degrees below what we’ve been experiencing for the past several weeks.

Derek and RoynaFriday at work was a whirlwind of meetings, including one held off site at another local law firm.  I got home a bit early because one of my vanpool riders took the day off, but within fifteen minutes of getting home, my son and daughter-in-law arrived from their all-day road trip from North Texas.  We visited with them for an hour and half, when they left to drive into Kansas City to spend the evening with several of their friends who still live in the area.

Terry cooked an excellent southern comfort food type dinner of chicken-fried minute steaks, organic green beans with turkey bacon, mashed potatoes and home-made white gravy.  Too bad the kids didn’t hang around long enough to chow down with us.  Terry and I let our food digest a bit, watching the Olympics until the skies darkened enough for some star gazing.

I grabbed the XT8 (affectionately known as ‘Dob’) and carefully carried it out to the lower backyard.  This time I took a small table to put my charts on.  I set my case of eyepieces on the ground.  I brought out the Intelliscope handheld device to attempt an alignment.  This device, unlike my ETX-90’s AutoStar, is only used to identify objects, not ‘go to’ them (since the XT8 does not have any motors).  The Intelliscope can help you find objects with a warm/cold kind of seeking system.  I still haven’t bought a stool to lean against, so my back aches a bit this morning.  I did a two star alignment, finding and centering Arcturus first, then Vega.

I wanted to revisit the Double Double in Lyra to both confirm that I could find it by star hopping and to attempt to see the double within the double.  I asked the Intelliscope to ID what I had centered in the eyepiece and it claimed I’d found the Crab Nebula.  Hmmm.  That’s in the constellation Taurus, which isn’t visible until early morning hours in the east.  I must have done something wrong in the alignment process.  I powered off the Intelliscope device and made a note to myself to re-read the manual in the morning.  Since I’d already found Vega, I spent several minutes comparing my star atlas to what I was seeing in the finderscope.  I found Epsilon Lyrae and observed it with 26mm, 15mm, 9mm and a 2x barlow (using the 26mm and 15mm).  Despite the apparent clearness of the skies, I did detect some haziness and thin stratus clouds overhead.  That may have inhibited my ability to split the doubles within the doubles.

I hopped over to Albireo in Cygnus, just to make sure I could find it again without referring to my star atlas.  I used a trick I had read about from some artists who do astronomical sketching where you defocus the stars, especially doubles, to discern their different colors.  I did this while observing Albireo and I could clearly see the red and blue for each star in the double.  I stretched my back for a few minutes and stared off to the northeast, at Cassiopeia, which I could clearly see as a distinctive ‘W’ shape.  I could not see the constellation Perseus, but I did see one or two meteors radiating from the space between Cassiopeia and where Perseus should have been visible (but wasn’t because of the haze and light pollution from the prison just north of my location).

I returned to the scope and began a star hop around Lyra in search of M57, also known as the Ring Nebula.  This was a test, for me, not only of my ability to find this fuzzy smoke ring, but also of an 8-inch telescope’s ability to cut through the obstacles inherent at my closest observing site (my backyard).  I surprised myself.  I found the nebula, quicker than I thought I would, and I even saw it through the finderscope.  It probably helped that Lyra was almost straight up above me and the telescope, meaning I had less atmosphere to peer through.  Using averted vision, with the 9mm, I could clearly see the ring.  I used the background stars to focus, because you can’t really focus well on a smudge that’s fuzzy and faint.

Since I found and saw a nebula with the XT8, I wanted to see if I could find a globular cluster next.  And I just happened to know where one was.  M13 in the ‘armpit’ of Hercules (see chart above) happened to be overhead, somewhere between Altair and Arcturus.  I had some trouble locating the stars that make up Hercules with my naked eye.  I took several minutes, stretching my back, to peer overhead, but towards the west, and Arcturus.  Eventually, the star dots connected in my mind’s eye and I found the constellation.  I oriented the XT8 to the general vicinity where I thought M13 would be.  I think I saw it through the finderscope, although I can’t remember specifically.  Using the 26mm eyepiece, I centered the globular cluster in my field of view and proceeded to observe this large dense cluster for several minutes with various magnifications.

I stared off into the northeast again, still trying to find Perseus and also Pegasus.  If I could see the Andromeda Galaxy (also known as M31), I would achieve a triple crown of astronomical observing from my backyard with the XT8 (1: nebula; 2: globular cluster; 3: galaxy).  I spent nearly a half an hour, roaming around my backyard, changing my point of view and line of sight to the northeast and east.  I found Cepheus, but no matter how hard I squinted or averted my eyes, I could not clearly identify the box that makes up the body of Pegasus.  Frustrated, and with an aching back, I decided to call it a night at about half past eleven o’clock.

I returned the telescope to the band room and replaced all the dust caps.  I hugged my hubby, for he had brought me a refreshing freshly made strawberry lemonade to enjoy while bending over the telescope for hours.  Off to bed and sleep, at least until the dogs started barking when Derek and Royna returned home (sometime after midnight and before five – not exactly sure as I tried to sleep through the commotion).

My alarm only fires off on weekdays, but most days I wake up fifteen minutes early.  Not Saturday morning though.  When I cleared the sleep from my eyes and checked the clock on my cell phone, it read 5:45 a.m. and I could already tell the eastern horizon was brightening.  I grabbed the tripod and camera and went out to the driveway to take a photo of the Moon approaching Jupiter.

Waning Moon Approaching Jupiter
Waning Moon Approaching Jupiter (Sat morning Aug 11, ’12)

If I happened to live in the Pacific, today I would be able to observe the moon occulting Jupiter.  But I won’t be too disappointed, since I can observe the moon occulting Venus next Monday afternoon, between 3:00 and 4:00 p.m.  I plan to take a pair of binoculars and my camera equipment with me to work.  I will setup on the top of the parking garage and hope I have a clear line-of-sight through the buildings to the west to see the occultation as it occurs.

But tonight I plan to find a dark sky location and take in as many meteors as I can, raining down from Perseus.  I better take a nap this afternoon and set an alarm for one o’clock Sunday morning.  Don’t want to miss the best meteor show of the year!

The Gray and the White

Purple Haze Next Phase
Prep complete, time to paint (Sun Aug 5, ’12)

We protected the purple walls with blue tape, brown paper and clear plastic drop clothes last weekend.  We wrapped up the room by Sunday evening, ready for Terry to paint the ceiling during the night, when that front southeast corner room would remain cool.  He did get the edging done before we took time out for dinner and an episode of Falling Skies.

Purple Haze Next Phase
Terry moving the ladder while cutting in the ceiling.

I woke up Monday to the same dingy gray ceiling, but I wasn’t complaining.  Terry could take as much time as he needed.  I headed off to work.  Terry painted as much as he could Monday afternoon, but ran out of paint at about the halfway point on the ceiling.  I saw a trip to Home Depot in our future for more bright white ceiling paint.  Terry thought about buying a five gallon bucket of ceiling paint, because we also have to paint the vaulted ceiling in our bedroom before we proceed with flooring in that room.  The $103 price was a bit of a shock, but we compromised and bought a two gallon variety instead for a bit over $40.  We reviewed the hard wood flooring options available, still not happy about having to order what we wanted and have it ‘quick shipped’ to us a week to ten days later.  Nothing ‘quick’ about that, if you ask me.

Purple Haze Next Phase
The Grey and White Ceiling

The ceiling remained half-gray, half-white for a couple more days.  I came home Wednesday evening to a bright white ceiling and the smell of drying paint.  We turned on the ceiling fan and retired downstairs for dinner and an episode of Chopped.  A thunderstorm rolled through Lansing while we ate, dumping some much needed rain on us and gracing us with a beautiful double rainbow.

The rain demonstrated yet another home maintenance issue to resolve before the drought ends in earnest.

Rain with Thunderstorm

Terry finished painting the ceiling Wednesday, applying two coats of the bright white ceiling paint.

With the ceiling dry, we could unwrap the room, leaving a huge pile in the middle of the floor to confuse the dogs.

This concludes the renovation of the top of the purple room. Next, we’ll tackle the floor, once we decide on whether we’re just doing this one bedroom, or all the bedrooms on the top floor.

Moon Overtaking Jupiter and Venus

Venus Jupiter Moon
The moon overtaking Jupiter and Venus

I fell asleep amid visions of rainbows and towering gilded sunsets dancing in my head. I woke up to clear skies this morning. Clear enough that I drug the tripod out and stuck the camera on it for a few minutes during the five o’clock hour before the sun began bleaching the eastern horizon.

Jupiter still hugged close to Aldebaran, but the most surprising sight for me was Orion visible, appearing to be lying down on the eastern horizon.  I could see most of the stars in that constellation, but the moon and Venus shone significantly brighter.

As the week wears on, the moon will pass by or through the two planets.  I plan to take more early morning photos until the new moon.  I am especially looking forward to the opportunity presented Sunday morning, when I may be able to capture Mercury in addition to the objects shown above.

I may be staying up all night Saturday to watch the Perseid meteor shower (if you follow that link to Sky & Telescope‘s web page, you’ll see a beautiful photograph taken by local phenom astronomer Fred Bruenjes, a fellow member of the Astronomical Society of Kansas City).  The weather, in addition to being much cooler, may cooperate and keep the skies clear.

I should probably take a nap Saturday or go to bed early, and then get up after midnight and drive somewhere, probably northwest of my home, to a darker sky location.  Then, I should be able to see more meteors streaking through the sky, than if I lounged around in my backyard, peering through the local light pollution and leafy tall trees.  But I doubt I’ll be able to take a nap, because I am also expecting out-of-town visitors for the weekend.

No rest for the aspiring amateur astronomer.

Daytime Observing: Part Two

Just before one o’clock, I took a break from prepping the purple bedroom for ceiling painting and went down to the lower patio to try some solar observing with the XT8.  The telescope was still in the shade (barely) but could be tilted into the sunlight out of the shadow of the house.  This created the ideal observing site, for me at least, as I could stand mostly in the shade and still use the scope to observe the sun.

I removed the dust caps and installed the solar filter on the end of the tube.  I selected a 28mm eyepiece, which would show me the entire solar disk.  I looked down the tube to the ground and used the silhouette of the scope to orient on the sun (the smaller the shadow, the better aligned).  Bingo!  Found our closest stellar neighbor on the first try.

I could clearly see six sunspots.  I tried the 15mm and the 9mm, but became disappointed in my inability to achieve a crystal clear focus when I zoomed into one of the sunspots.  I nudged Terry away from his computer in the band room to see what he thought of the various eyepieces and how well they focused on the sunspots.  He seemed to have the same experience I did.  The 28mm provided the best and crispest view.

After a few minutes out in the heat, I decided enough was enough and brought the telescope back into the house, carefully putting away the solar filter in its protective cover and box.

Daytime Observing: Part One

I got stood up on my second date with Dob thanks to the clouds.  I just wish the clouds had produced some much needed rain to relieve the extended drought Kansas and the rest of the Midwest is suffering under this summer.  I woke myself up in the middle of the night, checked the night sky and could barely see the moon for the clouds, so stargazing was a bust.

Even later, when I work up again (around four thirty), I peered towards the eastern horizon and could almost see Jupiter and Venus through the thinning clouds.  An hour later, I checked out the back side of the house and I could clearly see the moon.  The clouds had left.

I eyed my small ETX-90, huddling in ‘time-out’ in the corner behind the couch.  I thought about the XT8 downstairs in the band room.  I debated with myself which one would be easiest to setup outside to observe the moon after the sunrise.  The Meade is lighter, but requires the battery pack, Autostar hand controller and alignment.  The Orion I could just carry outside and pull into position.  The Orion won that coin toss handily.

I setup on the lower patio next to the hot tub.  I grabbed my case of eyepieces and my Sky & Telescope Moon Map.  I wanted to find a couple of more lunar features listed on the Astro Quest.  With a 25mm eyepiece inserted into the focuser drawtube, I centered the moon in the field of view.  Then I checked the finderscope’s alignment and fine-tuned it to match what I could see through the telescope.

Sea of Tranquility (courtesy Wikipedia)

I easily located the first feature: the Sea of Tranquility.

Next, I wanted to locate the Julius Caesar crater, which just happened to be located on the western edge of Mare Tranquillitatis.

I switched out eyepieces, using a 15mm and a 9mm.  I attempted to use a 4mm, but could not get a clear focus or possibly enough light to discern any lunar features.  I returned to the 15mm to do some close observations of the Julius Caesar crater.

I eventually tried to find two other features: the Alpine Valley and the Straight Wall, but I will need to wait for the terminator to create shadows in those areas before I can confirm the observation.

I left the XT8 outside, putting all the dust covers and caps back in place.  I plan to take some time this afternoon and do some solar observing as well, since we are at the peak of the sun’s eleven year sunspot cycle.

Purple Haze Phase

Purple Haze
Spare Bedroom #2 – Purple Haze (click image for rest of album)

I can thank my daughter for the choice of wall colors in my library and the other spare bedroom on the top floor of our home.  As you can see above, my daughter transformed an otherwise boring eggshell colored wall to eye-popping purple.  Her other spare bedroom, which I took over as my library, she foreshadowed in green, perhaps predicting her eventual defection to the University of North Texas? (Go Mean Green!).

In the green library, with the brown lounger, on hardwood floors (Aug 2011)

I received news last week that my son and his wife will be visiting us the second weekend of August. This finally spurred me out of my summertime torpidity and got me to cleaning out the aforementioned purple bedroom. I asked Terry if we could get the hardwood floors installed before Derek and Royna arrive. He countered with “I need to paint the ceiling before I put the new floor in.” Why, you might ask? Well, because my daughter, with the impetuousness (and impatience) of youth, did not protect the white ceiling from her purple paintbrush.

Purple Haze

I spent a couple of evenings last week sorting through empty boxes; old wrapping paper; even older clothes (a leftover tuxedo my son wore in high school ten years ago for a choir uniform); baseball and football trading cars; parts of a RC car; a skateboard; some stuffed animals; a laundry basket full of books; etc., etc.  Some of it even made it all the way down three sets of stairs to the basement storage room.  A few items just made it across the hallway into the master bedroom or the library.

I found the floor by late afternoon on Saturday, enough to sweep.  Terry brought up the five-in-one ladder so he could start taping off the walls from the ceiling.  This morning, I picked up where he left off and began putting rolled brown paper over the top of the first layer of painters tape to which we will eventually tape some plastic drop clothes.  Terry should have the ceiling painted today.

Then it’s down to the floors.

Movie Review: They Were Expendable (1945)

They Were Expendable (1945)

3 out of 5 stars

Not exactly what I expected from a Ford/Wayne film.  Not sure why Donna Reed even bothered to appear in it.

Filmed during WWII, but released after the war ended.  I just didn’t connect with the characters.  I need to find a better or different film to get a feel for our fight in the Pacific (outside of Pearl Harbor films).

It felt war weary, although it was about the Battle of the Philippines early in WWII.

Similar to The Desert Fox, the musical score made heavy uses of the Navy Song “Anchors Aweigh” and the “Battle Hymn of the Republic.”  I did tear up when I heard “Taps” played on a harmonica for a slap-dash funeral of two crewman of Wayne’s destroyed PT boat.

My First Date with Dob

Orion SkyQuest IntelliScope XT8
Orion SkyQuest IntelliScope XT8

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
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.

Orion SkyQuest XT8I 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.

Orion SkyQuest XT8

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.
