The birth of this image was a long and painful labour! The acquisition of this 6 panel mosaic started in mid January and didn't finish until the end of March (a total of more than 37 hours of integration). The subs are all over the place with varying seeing conditions, suburban light pollution and varying phases of the moon. I've made many stumbling attempts at processing the images but ending up with a good mosaic wasn't possible until a couple of days ago when I found a PixInsight script that has only recently been released that saved me from dumping the data.
The panels were registered using the PixInsight "MosaicByCoordinates" script and then integrated using a new "PhotometricMosaic" script by John Murphy (see his post on the PixInsight forums at https://pixinsight.com/forum/index.php?threads/photometricmosiac-2-0.14838/).
For anyone putting a mosaic together with PixInsight, the script is worth checking out. Hopefully it will included in future PI releases as a standard script.
More details of the image and a link to a larger version are on Astrobin (https://www.astrobin.com/full/izxe35/0/). The mosaic has lots of problems but this post is more about the script than it is about the image.
