8 sec. max exposure...

Hello all-

You'll probably recognize this thread immediately as a "newbie" (read: idiot!) question, but hey, I fear no loss of dignity. I've been involved in amateur astronomy for a little over a year now, having enjoyed the views from my 8" Meade, and have always had my eye on astro-imaging, either via traditional film or digital.

I'm just an impoverished college student, and the associated social atmosphere has got me saving up to get a digital camera, mostly for non-astronomy reasons. However, it would be nice if the camera I buy would also have a decent fare in astro-photography. So, I'm looking at buying a Panasonic DMC-FZ10 (or FZ3, if the money does not flow as I hope). This camera is 4MPs, accepts aftermarket threaded lenses (which means that I could possibly find some kind of an adapter to get it attached to my scope, correct?), but the max exposure time is only 8 seconds. Bummer!

Being perpetually broke, Canon Digital Rebels and Nikon D70s are absolutely out of the question. I'm familiar with stacking techniques and all that - I mean, I've never done any of it, but I know the process and why it's done. I guess, to make this incredibly long introduction come to the real point, will an 8 second max exposure time produce decent images of deep-sky objects, like nebulas and the like? How many images do you think that this will require?

Any imput is greatly appreciated!! I've been reading the forums on here for a long time, and it is my opinion that y'all are the cream of the amateur crop. Talk to you later, I'm sure.

here is a good link in finding a camera with the options you want.

http://www.dpreview.com/reviews/compare.asp

the most critical items to look for are

Remote shutter capability (or self timer function on camera)

Manual focus capable

30 second exposure

can the camera accept adapters (see link below)

ISO up to 800 or higher
noise reduction


anybody eles have any other must have options for non-dslr digi cams?
