Hi Allan,

Thanks for that. I am not quite sure what you mean? I need to maintain a specific spacing between the flattener and CCD. The only other option I tried was to bring the OAG directly attached to the flattener, and placing the spacer to maintain the correct distance between flattener and CCD after the OAG, therefore reducing the focus distance to the guide camera. This proved unsuccessful. It would almost seem that I need to put the OAG in front of the flattener, but I am not sure how I could accomplish that as the flattener has a 2" nose piece.


Cheers,

Daniel
