So I am finally getting out in the wilderness on vacation and I thought it would be a great idea to do some astrophotography. I thought of getting a simple enough Nextstar 4SE, but I have a bigger budget and maybe I can get a bigger diameter and aperture. So my question is, which telescope should I get in order to photograph the deep space objects. I might also need a DSLR in addition to the telescope, and I'm not sure if the GPS is built into most of those scopes - so separate module? something I can just hookup via bluetooth or some other ways. So essentially: high quality optics, at least 6", PC/MAC control, DSLR compatible or proprietary builtin camera, GPS support, Equatorial mount. Budget: $1000-2000 Fine if it is used Any advice?
