How much telescope do I actually need for astrophotography? I've done the 'sparkly curtains behind landscapes' form of astrophotography for years with DSLRs, lately full frame Nikon. I know what I'm doing with the camera, and want to take the next step into incompetence with telescopes to point at stars with a camera attached, but I'm getting conflicting advice on what kit I need.

One group are saying 'basic motorised Newtonian will be fine' - e.g.

Another are saying 'that's not powerful enough, you need a cadiotropic goto like

They're obviously very different bits of kit...! And I can see both arguments TBH. Either one is trying to waste my time with inadequate kit, or another to waste my money into his pocket with overspecified kit.

Help....?
Electronic viewing is filling the area between traditional eyepiece viewing and Astro Photography. Electronic images may be viewed live, near live and with digital processing on the fly as the image is viewed or processed after the images have been collected.

The cameras have lower resolution but higher sensitivity than DSLR's and astro photo cameras. Short exposure time are the norm. Imaging/processing time is generally measured in seconds and minutes instead of hours. Stacking algorithms have been integrated into the viewing software. While tracking is still necessary the software is much more forgiving. People are viewing/imaging DSO's with Dobsonians.

I use Mallincams in my observatory. They are used with a 10" SCT, a 5" SCT and several Canon DSLR lenses.

One has the choice of going big and beautiful or small and good enough is good enough.   

Take a look at the Mallincam io forum* and judge for yourself. They have a photo section with thousands of images and answers to the questions those interested might have.
