Re: APPM Model when changing camera

Hi Sam,

You could do a short APPM run of 10-20 points with the verify option enabled in APPM. This will indicate how well the other camera works with the other camera's model. There shouldn't be much difference if the cameras weigh about the same and the telescope's position in the rings is not moved.

Mr Gralak,

I would appreciate any experience or thoughts about using the same pointing model when the camera is changed
on the same scope .
I realize that ideally one would want to redo the pointing model, but I wonder what the theory would say if the only
thing that changes is sensor size and pixel size (assume camera - scope connections are equally rigid).

thank you
