Another go a this for the ASE Caldwell Project. A really tricky one this. Hidden in the dust from our own galaxy, this would actually be naked eye brightness if not obscured. From two sets of data but still challenging.
Well the Soul Nebula Mosaic anyway. 5 panes in the end. First 4 panes (see below) should have done it but I suspect platesolving failed and I had to do another pane the next night. APP is brilliant at stitching together and blending in panes – even from different sessions.
