I'm looking into buying a camera for my telescope to begin astrophotography. My telescope is an orion 8" dob. I know I probably won't be able to do very long exposure images because it's on an altaz mount, but I've seen promising results from stacking. I've dipped my feet in the water just by taking images and videos with my phone's camera but I have no mount for it so it isn't ideal. I was wondering what y'all would recommend as a beginner astrophotography camera. I'm leaning towards a DSLR because my mom wants to get one already for daytime use. Our budget is about $500 but buying used we might be able to get something a little better. I've also seen eyepiece cameras which seem a little cheaper but I haven't found much information about them.
Also what other lenses and extra equipment will I want/need? (Aside from a T adapter)
If Mom wants to get a DSLR, get a DSLR.
As for astrophotography, it can and is done with what you have. It is limited in what it can do. All levels of equipment has its limitations. A dob and a DSLR. That is OK. Learn with it, invent ways to get images.
What I am stressing here is patience. Don't rush into anything just because. Astronomy is fun, and frustrating. Astrophotography is also fun and frustrating...on a different level. Take time to learn the levels. Astronomy is NOT an inexpensive hobby, mistakes are plentiful, not very many are cheap.
Take Bob's advice, post # 3. I said before astronomy is fun and frustrating, it is also a learning experience. You always should learn from what you do or did not do. In your time that you are learning, save for what you might want or need. Remember, what you want now, you may learn, you don't need it later - you may need something else instead.
That is why I stress patience.
Equipment is expensive enough, don't make more expensive by having to sell it later because you really needed something else.
Most of all, whatever you do, enjoy what you do. Share it with others as well. Joe
