Yeah, I know an alt/az mount isn't great for imaging. I might be able to get a 1/2 second exposure at best with the Moon or Jupiter. Or maybe a dim shot of the Orion nebula. The scope has an f/5 mirror. I'm not expecting much. But it's worth a try if the adapter is only $10. It's gotta work better than holding a point and shoot camera up to the eyepiece.
A major problem with astrophotography is that it's complicated and unintuitive. The camera is nothing at all like your eyes, as far as astrophotography is concerned. There's a gigantic chasm between taking images of sunlit objects in the solar system, and even "bright" DSOs.
With the Moon and planets, 1/2 second exposures are far too much. You'll get solid white balls of light. You actually use exposures more like daylight photography, say 1/100. That will work fine with your mount.
The images will be somewhat blurred by atmospheric turbulence, seeing. There's a technique called "lucky imaging" that makes this better. All this is covered in his excellent book for beginners.
In contrast, 1/2 second is woefully inadequate for even "bright" DSOs. Taking those images is like taking pictures with a long telephoto lens. At night. In a moving car. <grin>
It's not that your mount is "not great" for that. It's that it's hopeless. An exercise in frustration. Taking DSO images is not at all like visual astronomy, not just putting a camera where your eyes were. It's _completely_ different. The tiny pixels can work magic, but only if used correctly. They have needs. <smile>
The cure for that is to lose the telescope, which just messes things up. Take DSO pictures with a camera and a lens. You can start with just a tripod, move up to a camera tracker. Store bought ones cost $300-500, you can DIY a "barndoor tracker" for much less. All covered in this excellent book.
Short posts here can only do so much, really only answer specific questions. I've tried to be responsive to your thread title. <smile>
But the books are the real answer to getting into this, even in a small way. They're "astrophotography for ordinary people". <grin> I pretty well guarantee they're worth the money, whether or not you take this far.
