Thanks for your opinion and advise, iceman. I think I may be using the wrong terminology. Last time I did any sort of astrophotography was 15 years ago with an Olympus OM-1 (if anyone remembers that famous camera!)
Can I clarify some of what you've mentioned: A DSLR is a common digital SLR "still" camera - understood that one. A DSI? are you referring to a CCD imager? i.e. a live capture image with a video output that can connect to a PC and appropriate software?
Actually this is what I want to achieve. A C11 SCT, and a "live capture" CCD imager such as
here connected to a notebook. Will this allow me to capture DSO's?
I sort of understand the concept of still, long exposure photo's will produce better images, due to the long exposures. But can the same results be achieved from live CCD devices and PC software?
Oh boy, if I haven't confused you now, I'm going good. Thanks in advance.
hoo roo.
