Funny you should mention it Suavi and Col....I would love a camera lens system too
I do have a spare SXVH9 CCD camera lying around gathering dust, which although it has a small chip, attached to a 50mm lens would provide an approx 10deg X 8deg FOV... could be interesting..?
As for the theoretical load limit for the NJP mount..?...clearly it could be infinite
