with my 127 Mak but with slightly different components which might be what you are looking for. I've used an Antares 0.63 reducer screwed right into the scope followed by a celestron 50mm extender. Then used the usual 55mm backfocus setup with 585mc pro. This reducer needs 105mm back focus so there you go. I think it's the same for Celestron reducer but I read that the it produces heavy vignette with Maks and Antares performs a lot better for reduction and correction. For focus I made a DIY solution to attach ZWO EAF to the original focus knob instead of a crayford focusser. This works well. I hope this helps.Â
