I'm looking at getting an Edge HD 9.25 in the near future, if they ever get back in stock, and was looking for some advice. I currently have a CEM60 mount and would be imaging with either an ASI1600MM, ASI178MM, or ASI224MC. When I get the scope, I was also looking at the Celestron 0.7x reducer and Celestron OAG. For guiding, I've read that the ASI174MM mini is a good match for off axis guiding with this scope. Aside from your normal range of spacers to achieve proper back focus, can anyone think of anything I'm missing or have any advice? I've been imaging with an assortment of refractors and DSLR lenses so I have the basics down good, just new to owning an SCT.
