I have been meaning to ask about this for a while now. I use this scope (actually a variant with the helical focuser) and camera (non-mini) combination. But the scope attaches to a finder shoe and the bracket to the shoe is an integral part of the scope.
But all the recommendations all over CN are to NOT use a finder shoe but to attach the guide scope with rings at two separate points. Can I even use this scope for that (how?) or do I need to replace my guide scope.
Yes. The recommendation is sound. And unfortunately, it has been misinterpreted as "if you use the finder shoe, your images will be bad."
The trouble with the recommendation, is that a good solution is expensive. Most medium-priced scopes have no facility *as sold* for attaching a guidescope correctly, and many if not most guidescopes will require replacing the mounting hardware they come with.
If you have an extra $300 lying around for perfecting your guiding, by all means do so--but you will be MUCH better off switching to OAG in such a case, for better guiding, easy portability between scopes, and complete elimination of differential flexure.
Meanwhile, using the finderscope shoe is MILES better than not guiding at all.
Note also that some guidescopes are sold with two rings, which attach to a base... which attaches as a single point. That doesn't do much. THIS is the ideal mounting--and note that the top dovetail bar on your scope is extra, and may need replacing the rings or other mounting hardware your scope came with.
