Hi Paul
Looks good to me; mosaics are quite challenging and you have done a good job. My experience with autostitch is that it sometimes creates an image with "barrel" or "pincushion" distortion where the middle is expanded or pinched respectively, rather than linear. Not been able to pin this one down yet.
Here is Gassendi from last night - only 15 frames so it’s a little rough.
Cheers
Dennis
