[AZ-Observing] Re: TouCams Available (NOT)

I'll go for the (relatively) noisier frames. They can be fixed easier than
getting too few frames. The only thing to do I guess is to take it into
testing and see what it can do. I don't think I would pay $92.50 for a Pro
model tho (gee, there are Toucam connoisseurs). I'm just experimenting. If I
can't get some decent planetary/Moon images out of it, I suppose I could
make a webcam out of it.  :-)

I don't know why my posts took 4 days to show up. Guess I don't need an I-17
update anymore.
