gonzostar Posted August 11, 2017 Share Posted August 11, 2017 Hi I have being attempting to image M31 over a few nights, days apart! (August Weather) When i came to stack the light frames, some of the images ovrerlapped from different nights. So you can see the edges of frames on main im Is this possible to change in DSS? ie which settings? Or is it possible to get rid of these frame edges in photoshop? Thanks for any advice Cheers Dean Link to comment Share on other sites More sharing options...
Uranium235 Posted August 11, 2017 Share Posted August 11, 2017 Use stacking mode "intersect" in DSS, it will auto-crop it for you. But even after that I would manally crop it again by a small amount to take out anything the autocrop may have missed. Link to comment Share on other sites More sharing options...

gonzostar Posted August 11, 2017 Author Share Posted August 11, 2017 ok for some reason i got this section only with "intersect" on dss. Do i need to make another adjustments? Cheers Dean Link to comment Share on other sites More sharing options...
Uranium235 Posted August 11, 2017 Share Posted August 11, 2017 Perhaps you have some wildly mis-aligned frames. It might be worth doing a manual inspection of your images and taking out the worst offenders before stacking. But if you cant get intersection to work, just crop the stacked image in photoshop or some other image editing program (its a basic tool... even paint has it!).

gonzostar Posted August 11, 2017 Author Share Posted August 11, 2017 Ah Just had a look and some of the frames had angles of 25degrees from the alignment frames! Link to comment Share on other sites More sharing options...
