Three set hex screws are used to hold it in place. It came with both nylon and metal screws, but said the metal screws will hold equipment tighter. The power cord for the mount is not working, so had to work around that. Used the solar filter with the 55 mm to try things out. Focus was quite easy.
Rough adjustment is made the normal way, then the motofocuser is used for fine tuning.
I suspected the greater the magnification, the more effective the motofocus would be. Put the 14 mm in and refocused manually to the best I could get it. I was slightly out of focus. The motofocus now really started to strut its stuff. But the really big step was with the 9mm.
