Hi -- I have 30 pics that form a stack of star pictures with which I intend to do a median image average with gmic. They are a bit unerexposed. I'm trying to use hugin to align them.
I mask out the ground and horizon, etc, and have hugin align just the star field. The default cpfind doesn't do a great job, so I've created my own CP detection params: --fullscale --sieve1width 15 --sieve1height 15 --sieve1size 100 --kdtreesteps 500 --ransaciter 2000 --ransacmode rpy -o %o %s ...this has improved things a lot, and the remapped images are very close, but it's still not close enough to do the median image calculation. The first and last image (representing the largest spatial shift from the stars rotating in the sky) are still off by 5 or 10 pixels. I don't really understand the parameters I'm playing with (except maybe the sieve* params) so I'm just ignorantly shooting in the dark. Any tips on how to make this better?
