Lens focal Length for 290

Post by Chopperkirks » Sat May 09, 2020 3:21 pm

I have a 290MM and a 290MC and i am looking to get CS mount lenses for them to use in a project. What is the focal length on the 290 so I can look for lenses which would give me the best results? Thanks

If you want a best result, you could look at the back focus of the CS lenses rather than the camera. And we have T2 To CS or C lens adapter which you could refer to(https://astronomy-imaging-camera.com/pr ... cs-adapter).
