Thanks. I've been busy with other projects. I'll try working through the Russel Brown procedure in AP. If I get stuck, I'll post a question.

I am a newbie, both to Affinity Photo and to advanced eclipse processing. I have been struggling to use the Russell Brown method to process some 18 images of the corona that I managed to capture, without success. owenr, I would appreciate any tips you can provide on how to do it in Affinity Photo. Thanks.

A_B_C, unfortunately this does not work for sky (star) images with a silhouetted foreground. I have tried all possible options offered on the Affinity "stack on load" feature, and none works. While I don't know what algorithm Affinity uses for alignment, I believe the presence of a large foreground element (relative to the stars in the sky) is what causes the alignment of the stars to fail. Even if the foreground is completely black-out, the edge between the ground and the sky comprises a large number of pixels. The video I referenced shows how to mask out the foreground and align only the sky portion. After stacking and adjusting the composite image the foreground is re-inserted. The video shows in detail how to do this in Photoshop. I'm looking for a way to do it in Affinity. The lack of an Auto-Align tool is what is hampering me.

The following short video tutorial shows exactly how to do in Photoshop what I want to do http://www.shutterevolve.com/landscape-astrophotography-noise-reduction-with-image-stacking/ Please tell me how to do this in Affinity Photo, or point me to a tutorial that tells how. Thanks
