Hi,
I'm trying to create my first mosaic of M31 and it's surrounding space. However, I can't get a nice looking image. It's not seamless and it has dark or multicolored spots in the area around some of the stars in the overlap between two images.
I've tried running combining the two bottom images, then the two top images and then combining top and bottom. I've also tried combining top and bottom on the left side, combining top and bottom on the right side and then combining left and right.
In GMM I've tried multiple shrink and feather settings. I can get decent results when combining eg. the entire left panel and the entire right panel. It gets bad when trying to combine the left and right panel.
My workflow is:
Calibration, CC, debayer and register each panel.
Crop and DBE each panel
SA (Register/Union Mosaic with Frame Adaptation) on 2x2 and ending with creating a rough 4 panel mosaic (multiple gaps)
SA (Register/Union Separate with Frame Adaptation) on 2x2
GMM (various tries with shrink and feather settings) on the recent registered panels to create the image.
What am I doing wrong? I've spend wayyyy too many hours on this today and I'm just about to give up on the project.
I've uploaded my individual cropped and DBE'ed files. Could some of you take a look and try and create a mosaic and show me how??
