Modified SBIG STL-11000 M

The Ceravolo Astrograph is designed to fully illuminate the STL-11000M's 36 x 24.7 mm detector, but the supplied 2" diameter camera nosepiece is too small to preserve the astrograph's full field illumination at f/4.9. For astrograph testing purposes the camera's filter wheel was removed and the opening on the faceplate was enlarged. A custom 3" diameter nosepiece was adapted to the camera, as seen in the image below.
