Quote:Hi all,I think this theme has been discussed extensively, witha lot of exampes and tests by Darryl and others.Now I'd like to do the following:I have 3 images, processed and nicely the same size etc.Each image was taken 180 seconds long and evenly spaced60 seconds in between.Q: Can these images be derotated such that I can stackthese 3 images together?I have seen AVI derotation etc but can't make thishappen If someone would be so kind as to show me the rightdirection to take I would be more then grateful!!!!!Thanks a lot for any insight!

Quote:I think derotation is more important for mono camera to align R G B file.for color camera I don't see such benifitand derotate 3 images and stack seems won't improve much
