I have a Celestron C8, which has a focal length of 2032mm. I want to take pictures of the upcoming eclipse in August, but I'm using a Canon 80D and not a full-frame DSLR. This brings the focal length to an equivalent to 3251.2mm.
How should I go about taking the pictures? The crop factor will make an equivalent too zoomed in on the sun to take a good picture. But I don't know how the tube that screws into the ass-end of the CST will be enough for the crop factor. Should I buy spacers along with the tube and adapter? Or should I get an adapter that allows the usage of eyepieces, although I'd prefer it just having the 80D affixed to the CST
