However... some of todays webcams allow up to 1 hour exposures, and more realistically noise at the 3 to 6 minute subexposure level looks reasonable to me. Has anyone used such a camera (such as the larger chip Imaging Source... DMK... or DBK webcams)for deep sky images? I'm going to give it a try tonight with my DMK41 camera... there is a little bit more noise than I expected but I think it should work on brighter deep sky objects... -------------------- Rick Evans http://www.freewebs.com/revans_01420/ "The universe is there for us to see, but it cannot be understood without learning its language -- mathematics."
