Re: (ATMoB:Discuss) Question for the CCD'ers (off on a tangent, maybe)
Expanding on this topic a bit -- I just ordered a Minolta Dimage5 3.34
megapixel camera. I liked several things about the camera; it accepts
filters, has a relatively long (500mm equivalent) telephoto, auto
bracketing, and multi-priority exposures, much like a standard 35mm SLR. It
has very low light sensitivity, a remote cable and a Bulb exposure setting
up to 30 seconds.
The question, and I hope the answer is positive, is of course, can I use it
for any kind of astrophotography?
