It's been a long time since I've shot this one At least 15 years. So I decided to have another go at it the other night. I had guiding issues that caused me to dump half my images. I'm sure there's better processing to be done on this and can provide the raw Fits From APP or the XISF from Pixinsight if anyone is willing to give it try.
