Treasue Hunts and TGOs

by Mark Wagner

We had a great turnout at Coe last night for the end of year pot luck star party. There was way too much food, as usual when people do a pot luck. Chocolate torte, pork rinds, prawns, homemade Cajun gumbo, KFC, veggie platters, bottles of wine, all sorts of good eats. Thanks for Joe Bob for the Fosters, and Steve -newcomer and transplant from TACiego, for being aware of the old TAC traditions (you can bring the Fosters next time). Thanks to everyone for participating. The perimeter of the lot was full by sundown, temps were mild, almost spring-like. Skies were quite clear, and the roughly two dozen observers were at their scopes enjoying themselves. We did have a visit from CSAA, as one observer had locked keys in car - the driver was promised free food upon arrival, and did indeed make it up the windy road in what to my experience with AAA was record time. Interesting to see how quickly a car can be broken into!

Richard Navarrete and I were using our 18" Obsessions to hunt objects on the Herschell 400-II list. A list of objects observed are at the end of this report - they were mostly in lower Cetus and Camelopardalis. Open clusters and galaxies, some were very challenging, leading us to speculate that the transparency was poor - as the clear sky clocks had predicted. The CSCs definitely were incorrect regarding the cloud cover, and especially humidity - both forecast as ugly, but turned out to be non-issues. What was an issue was a stiff breeze that started a few hours after dark, and kept up until (and not surprisingly) we had finished tearing down our scopes.

There were a few visitors during the night, one being Stacy Jo's mom, here from Colorado Springs. Nice woman who was enjoying seeing her daughter out with friends, and taking in the outstanding sunset. Another was a park volunteer, Lisa, who partook in the pot luck and had fun picking out some of the dim galaxies in my scope. After years of people asking about finding objects by star-hopping vs using go-to, Lisa in two words captured what the fun is in star-hopping. She referred to it as a treasure hunt. That was it! It is the kid part in a lot of us, the challenge and fun. I'm sure even die-hard go-to telescope users remember that kind of fun.

Many of the objects on the list were difficult. Some of the galaxies were nothing more than mere haze, some, surprisingly large - but almost not there. The wind would blow the scope off the object while we were at the computer, confirming position. I began thinking of these as Transient Galactic Objects (TGO - pronounced like the sandwich shop chain). They'd be there, then they'd be gone. TGOs are frustrating, and usually weather dependant. The wind created many TGOs and finally, put an end to the evening for several observers.

Finished by observing some eye-candy. M42, NGC1980, the big bright M-opens, all spectacular. It is easy to see why we drive to Coe and skies even darker still, comparing last night's views to those in town, at MB, or Houge.

And, as expected, as soon as the scopes were in our vehicles, someone said "hey... the wind's died down"...

And it had. I hope the mass sacrifice served well for those who remained. It was a fun night, good food, good crowd of friendly folks, other than wind among the best conditions I've seen for a December in many years. A good way to end the deep sky observing year.

I get to be the first to say, on to a great 2005...
