Mark, your posting got me to look for Vesta this year, it's very close to Alpha Piscium, and my 10x42 Leupolds do just fine; it's mag 7.0. I'd never identified...
Teri, tried to Google TTrac and various combinations, no result. Could you please give more info, like a company name? Thanks for your response. Orrin ... ...

I tried to post this @ TAC's mailing list several times but was unsuccessful. If you are calling the LS office to schedule the parking lot gates to be open,...

Last Saturday at Willow Springs I took a peak at Vesta several times over the course of the evening at 285x and was able to see it slowly move against the...

I usually don't forward commercial postings, but this one is atypical, would seem to be one-time and possibly benefit people on this list.... ... Subject:...

Orrin, Why not build a simple "barn door tracker"? Google up the phrase and see lots of hits, lots of plans, etc. They work just fine... and will help you...
Paul, will see what comes up when I search for that phrase. The commercial version, they want $661 for the tracker and another $150+ for the polar alignment...
Not to belabor what you'll no doubt see on Google, picture two pieces of wood hinged together. Point the hinge pin at polaris. Put the camera on the top piece...

Paul, Jeff and Teri, thanks. This looks like great stuff. The simple hand-driven version for my 70mm camera lens, then maybe try a more difficult version later...

After thinking about this overnight, I realize I could just use my 4.5- inch short-tube reflector as a guide scope, use the cables to manually keep the camera...
Paul, Jeff, Teri, et al: I found a website that gave me a concept for constructing a platform for piggybacking a camera on my 4.5" reflector, and using the...

Thanks for the report, Steve. Shoot! I didn't even know about it. I watched the moon occult Aldebaran in 1999: http://observers.org/reports/99.01.26.2.html ...
