ASTRONOMY

I have a Sony 7s full frames camera. If I use the classic connection with its t2, vignetting me. Do you have a connection that is right for me?

The vignetting on a full-format camera depends on two factors, one is the internal diameter of the fitting which is to be the largest possible. a t2 has a diameter of light passage of only 38/39 mm, this is the main problem. The second problem and the mechanical geometry of the optical tube that telescopes generally on cheap and very reduced.
