Zenithstar 61 without flattener - cannot get focus
I connected a Nikon D5300 to Zenithstar 61 using a T-mount and 2” adapter (no flattener). I couldn’t get focus even when the focuser tube completely moved out.
Has anyone else faced this? Do I need extender tubes to move the camera more behind?
I use fuji XT-10 with Z61 without reducer/flattener before, I can only get focus with the tube almost completely out, I guess you just need a extender.
P.S. with reducer/flattener, the tube is so much shorter.
