I am selling this ancient self modified lens.
A sudden thought came to me, why not attach it directly to a crayford focuser? It shouldn't be too difficult.
I have all the thread specifications, connecting adapters might not be too difficult to find.
I even removed the camera angle adjuster to test, but unfortunately, the focuser was a bit too long for infinity focus.
I believe that a short profile SCT focuser might work, and I actually have one. Might try again later, I just treat it as a short break for me.

Equipment shuffling
A further thought comes. I am trying to see if this CYCK could be attached to my Ranger tube so that the JMI NGF-CM could be released?
The answer is not simple.
The Tele Vue Ranger has a 3" 24 TPI thread, while the CYCK has metric thread.
I should have fabricated a SCT adapter for my Ranger tube instead of custom made for the NGF-CM. So it's very much irreplacable now.
I could go another route: attaching the ZWO focusing motor to the JMI NGF-CM? I might work but then it's not easy to adapt the NGF-CM to another telescope since it has nothing but a groove like attachment.
If I could find a NGF-CM SCT adapter, the whole thing would become possible. However, the JMI seem dead? It's not easy to come back such an adapter.
