Hi there,

I know this is an older thread, but I am also interested to know how the
astrometrica software behaves and how easy it is for satellite detection?
My approach is to determine the ra/dec with astrometry.net software. That
works reasonably well with the video I have from the Transporter 2 Mission
of this June. The satellites I detect myself. But it takes a while for both
(my code and the astrometry part).

Maybe astrometrica is better there. But before I start the 100 days trial,
I would like to know here if this can be applied also to leo satellites.

Best regards,


Andreas
