Hi Bob,
I have tried imaging C/2017 T2 Panstarrs comet last week. I have uploaded comet data from the minorplanets website as advised in help files and used attached plan.
ACP was centering the comet in the center of FOV, but, unfortunately, every time I got both star and comet trails on 600s exposure.
Then, I did the same using direct pointing and tracking with the mount and imaging through MaximDL. No trails on the comet (I attached both images from the same night for comparison).
Not sure what I may be doing wrong, is there any setting in ACP that I need to enable to be able to track the comet.
Thanks
Regards,
Saulius
