This unit utilizes a standard 90mm camera clamp that works with 90mm body cameras such as the QHY SBFL, The QHY 268M, The ASI/ZWO 6200 , 2600 and many more.
This drawing shows the QHY 77mm dovetail camera clamp installed in the standard model.
Some folks asked how to measure the sensor distance with the nose of the camera enclosed in its protected environment so Mark drew this diagram to help them out.
