What Equipments are needed for amateur astrophotography?
I'll like to know if any Dslr specifically could do good astrophotography, how it is attached to a telescope & what brand & type of scope.
you use a t-ring and t-adapter to attach the camera to your scope. imho, camera is the least important item if you want to do astroimaging, the order is something like this:
1. plenty of time, patience, and good imaging location
2. good mount (like a vixen gpd)
3. good small apo scope (like a megrez ed triplet)
4. good dslr (like a 350d)
i happen to have 2, 3, and 4. but not #1

Hello,
It really depends on what aspect of astrophotography are you looking at. Good DSLRs include (in my opinion
) the Nikon D70 or D70s variant, Canon D20 (I think) and many others. The types of DSLR that you may like to consider for astrophotography should have a "B" setting of up to 30 mins and good noise-reduction features.
If you're looking at taking star trails and taking wide-angle images of the sky, then a DSLR mounted with a tripod will be sufficient for time exposures of up to 25-30 seconds (dependent on which part of the sky are you shooting).
Piggybacking is another method- longer exposures of up to 30 minutes with the camera mounted on the back of a telescope on a mount and tripod. For short exposures of up to 3-5 minutes, the stars shouldn't trail much, but might trail considerably when the exposure time is increased to >5 mins due to errors in the mount drive and alignment.
Prime focus is the method described by ariefm71, which I totally agree with. This one is more tedious, but the rewards are in the beautiful images that can be achieved, as demonstrated by starfinder in his Mars images (Mars- Red Storm Rising), subject to exposure time.
All the best in astrophotography. Have a nice day!
