Hello, 

Im currently in the process of making my own test jigs for ccd tilt and collimation of telescopes. 

Im new to this so I have a few questions. 

The CCD tilt is fairly simple as I dont need allot of distance to do this test. But lets say I want to do a star test (using artificial stars) I would need allot of distance here. My question is this; can I just increase the distance of the filed flattener from the telescope to achieve a closer focal distance ?

Kind regards

Roger
