can somebody tell me what adapters are needed to attach my 585MC pro to my ZWO FFP65 telescope. The scope is 54mm at end. This is to get the required 55mm backfocus.

hotrodder19 If you do not use the reducer adapter, no need to get 55mm backfocus. If you use reducer and needs 55mm backfocus, there are some connection way for your reference. https://www.zwoastro.com/the-best-solution-of-55mm-back-focal-length/
