Best opensource/ free stacking software for mac for astrophotography


I am using snow leopard and mainly want it to automate the stacking as much as possible. I have seen that PixInSight looks pretty awesome, but that's not free, in-fact far from it, so I want something that is free that can do the same, or as much as possible.

Hugin might be your answer. At least it is available for the Mac and handles stacking of images (also into EXR-format), masking and distortion-correction of images. It is not per se meant for astrophotography, so you would have to know what to do.


As for automation (of the aligning) - I put each of my Stacks/Stitches into separate directories and just let a script run over all these directories, applying "autopano" or "align_image_stack" on all files in the directory. You have to check and correct the ready .pto-file afterwards.
