I'm learning to do mosaics in Pixinsight right now, and have a 4 panel image of M31. I made a rough mosaic in Star Alignment which I then separated so I have four images with blank space. When I try to run GMM with those files I get an error saying that current image height differs from first image height. When I go to check the sizes of all four images they are exactly the same. Does anyone have a solution to this?

well its hard to debug this without seeing the input images, but one way around all of this is to solve your 4 masters using ImageSolver and then save them to disk and put them into MosaicByCoordinates... then take the frames output by MBC and put them into GradientsMergeMosaic.

Do all four images have exactly the same dimensions? Let's say you have 4 3000x3000 images with 15% overlap. All four images would be something like 5600x5600 and 75% of them would be black.
