First attempt at a mosaic. I had issues with flats over correcting and ended up not using it which led to some odd gradients in 2 of the panels. Repeated attempts at gradient merge mosaic in Pixinsight did not eradicate the lines between panels so i'm not too sure what I did wrong. Nevertheless i'm glad it at least came together.
