I've been looking for a C-mount tilt adaptor for my new Basler camera to kill NRs but can't find anything anywhere. Plenty of T2s, but no Cs. I decided to make my own and it works like a dream. For anyone interested, here's how:
Firstly I purchased a metal C-mount to 1.25" nose piece. I then cut through the tube close to the base creating a gap, leaving a small (approx 1cm wide) bridge that could be deformed by bending. I ran some trials on my Lunt 60 to see how much tilt I needed to kill NRs with the sawn nose piece in place, shielding the gap to prevent stray light entering the camera. By adjusting the gap I found the point at which NRs disappeared, also checking with my Barlow lenses that this was true across the range of optics that I intend to use.
Once the gap was correct, I removed the nose piece and filled the gap with epoxy, smoothed it off and painted the adaptor black inside and out.
And the final result:
Hope this may be of some help to anyone with the same issue. BTW, it cost me about £10.
Stu.

Re: Low cost DIY Camera Tilt Adaptor
Nice one Stu, thanks for sharing. Any idea how much degrees of tilt you required?
