I noticed that MaxIm has several Pinpoint options only available with the full version. I've had a few problems plate solving with ACP Scheduler recently, for example one of my photometric star fields with multiple repeat exposures will successfully solve only a few of the exposures (say 1-2 out of 8). The ones that fail indicate possible wrong image scale, although that can't be the problem since the vast majority of images elsewhere in the sky plate solve just fine.

I'm happy to license the full version of Pinpoint if it would give me a better chance to fine tune the Maxim settings for better reliability. Also, should I consider changing from the GSC to one of the other catalogs? My FOV is 26x26 arcmins.

Thanks as always,
