Woohoo!!
I’m a Libra so this is naturally my favorite day of the year.
I feel so balanced today.
Have a great day!

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 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.
Later, I accidentally captured not only Mercury, but a passing plane, as it took off from KCI (northeast of my location).
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.
