Get an equatorial mount that can track the sky for at least 2 minutes with
little to no tracking error.
Start with a fast scope and a DSLR. The options here include expensive
F5-ish apochromatic refractors and inexpensive small F5 reflectors.
That said, it is helpful to know where to find the astronomical objects you
wish to image. If you don't have this knowledge, you either need to develop
it, or you need to get a mount that has the ability to get you on target.
Personally, I only got into imaging so that I could see more detail in those
objects that are hard to see in my scope. I could simply look them up in a
reference that has images, but it's fun to take the pictures, and process
them myself. This way I get at least a small sense of discovery. But my
point is more that I know where to find the objects I want to image, because
I've been trying to see them visually.
At some point however, deep sky imagers will make a move to larger aperture
scopes, longer focal lengths, and better mounts with DSCs or GoTo, in order
to target objects that cannot be seen with the eye at all.
Hope that helps,
Stephen
