Description

This is a picture with the new Sharpstar 2032PNT. This is a slightly cropped FF picture. The Sensor in SLR cameras is deep inside the camera. Vignetting is therefore big. I still do have problems with Flats. They look strange - making the picture rather worse than better.

The overall optical quality of the scope is really good, the corrector gives sharp stars over the full field of view. Corrected field works with FF-cameras.
