Day after Christmas Chicago Astronomer Star Party
26 December 2011
The coming week's weather forecast is calling for clear skies and decent winter temps. If so, let's do our first Post Winter Solstice Chicago Astronomer Star Party - last one(s) for the 2011 observation year.
Check for the updates here and on Twitter & Facebook, but if all is solid - I'll arrive on scene just west of the Adler building by 6:00 pm - if not sooner.
We will catch Jupiter, Venus and the Crescent Moon - as well as some DSO's for good measure. I'll lug out the C11 with the new Crayford focuser for it's first field test.
Let's see how many sessions we can squeeze in before this year ends...

If I get enough sleep through the holiday, I might be tempted to come out early for a solar session. My thought is for any interested (and available) astronomers to check out my solar filter set up. That way anybody wanting to gear up specifically for the Venus transit, or solar observing in general will have a frame of reference, and might help them decide if Baader-type film is right for their scope. And, of course, all the other stuff Joe mentioned above.

Joe, I'm highlighting how to find Uranus and Neptune for later next week, using the Moon as a guide. They should be easy for us to spot if clear. I'll have to see what my schedule is like that day - not sure if I can make it or not.
Jim, No color or optical expert, but color filters aren't used for the coloration of the object, but, as Joe said, for the different features that can be seen thanks to contrast variations at different nm. So even if you don't see the green, I'd guess that the contrast benefits of a green filter would still be effective, for example. May be totally wrong, but I'm with Joe. I also second his suggestion to try some out before plunking down hard won cash in case either we're both wrong, or you decide that it's a cool thing but just not worth the money.
