I got one of these Navitar clones (at least I think it is the same lens as the Navitar 75/1.3), an Astroscope 75/1.4. The rear end of the lens looks like this:
And here it is with a c-mount adapter:
As we can see there is too much of the lens sticking out from the back side of the adapter. That prevents not only proper mounting (the lens can't be screwed into the adapter and mounted without hitting the light baffles in the G1) but also focusing to infinity.
Now infinity is not of the greatest concern but I would like to try the lens in real use.
Are there any Navitar, or Astroscope, experts here? How do I proceed?
I could just cover the rear lens element and remel it down but I figure there is a better way to do it...
regards,
Jonas
