Table Mountain

Table Mountain is outside Ellensburg, Washington at about 6300 feet of elevation. Check the date above and put those two facts together. Yep, it was butt-numbingly cold. It froze overnight, but worse than that was the early dewpoint. We only got about 2.5 good hours of observation. Fortunately, those two hours were excellent. I'll summarize the equipment we used and the objects we found (caveat: I'm just starting out and Todd is a year or so ahead of me, with a few extra dark sky star parties under his belt, so this was definitely not a Messier Madness race).


Equipment

Todd's gear:

5 inch Cinta refractor, equatorial mount with the usual set of eyepieces and an ALP filter.

Olympus OM-1 for sky field exposures

Tirion's Cambridge Star Atlas, Nightwatch charts

Atmospheric Light Pollution filter

Green Laser pointer (this thing rules)

Chris's Equipment:

Meade LX-200 8" Schmidt-Cassegrain. This model has the motor drive and equitorial wedge. I'm spending my time learning to star hop and dead reckon, so I mounted the scope flat and didn't use the drive this trip (I don't have a travel battery anyway).


Tirion's Cambridge Star Atlas and Nightwatch

Nikon Coolpix 900

Meade 9mm, 12, 15, 22, 25mm Super Plossl eyepieces with Celestron Ultima SX Barlow (2x)

General Conditions

Surprisingly enough, there were several other groups on the mountain that night. We saw some nice equipment including Takahashi apochromat refractors, SBIG CCD cameras, a 12" Meade (the big brother to my scope) and a whopping 17.5 " truss-mounted Dob. Unfortunately, it was also bow and black powder hunting season so there were some hunters with white light discipline problems at the site.

As I said earlier, it was quite cold. Todd and I put up his tent and layered up all the clothing we brought. Truthfully, I didn't expect such a chill (the afternoon wind was biting) and I'm glad I packed the extra layers.

Objects

Dumbbell Nebula

Andromeda Galaxy

Wild Duck

Whirlpool Galaxy

M106

Aurora Borealis

Pleiades

Software I've been playing with...

I'm a computer guy, working for that big company in Redmond, Wa (yeah, that one)..so I have several computers around the house. It's natural to want to combine the astronomy gig with the fulltime job. Here's what I've been experimenting with:

DeepSky 2000 for the PC

XEphem running under XDarwin/OroborosX on my Ti PowerBook

Pocket DeepSky for the PocketPC

Thinking about getting "The Sky" from bisque software for my Ti PowerBook
