Since the eclipse is coming up in 2 months and I'm lucky enough to live very close to the path of totality, I want to be prepared for it. I have a DSLR here (APS-C sensor size, 1.52x crop factor) that I am planning on using to take some pictures.
I'm not an avid astronomer but I have an older Meade 6" Starfinder (Newtonian reflector) with a focal length of 1220mm. I have two concerns about this telescope: Firstly when researching camera adapters, I ran across quite a few people who were unable to obtain a focused image using prime focus (I believe eyepiece-projection would zoom in too much) with a DSLR and a Newtonian reflector telescope. The manual for the telescope indicates that you can move the mirror to alleviate this problem, however. Secondly, this telescope is quite large, with an equally large and heavy tripod and I am not sure I will be able to safely transport it on eclipse day.
So I am looking for suggestions for a telescope that is much more portable than my current one, has a focal length appropriate for eclipse photography with my camera (I think ~1200mm is appropriate?), can focus properly with a DSLR without needing to adjust mirrors, and is inexpensive since I unfortunately don't have much of a budget. I would say $500 max but I'd like to keep it as low as possible without being subjected to any serious optical defects. I like the look of the Orion Apex/StarMax 90mm Maksutov-Cassegrain telescope but have no idea how good it is. More expensive telescopes generally seem to have too long of a focal length for eclipse photography with my camera.
Any advice would be appreciated!
