Orion Deluxe OAG

Thanks Paul, Lester,

As I mentioned just waiting for some good weather to give it another try.

One more question I have a flatterner (P-FLAT 68) in between the scope and the OAG which has pushed my imaging chip well away from the recommended distance, I managed to get a couple of images last Monday night and have noticed quite a bit of star distorsions and vignetting on the outer edges, I guess flats should take care of vignetting would not improve stars, I imagine this is caused by imaging CCD distance to the FF.
Any suggestions??
I could remove the FF and see what it does to the images.

Ahhh if only the weather cooperated to carry out further testing

Regards
Jim
