So this is a real mongrel. I don't own the scope, camera or mount that most of the data was acquired with. I couldn't finish it as I didn't have the Red data in short subs for the core. Its only 90 mins LRGB for the nebula and 30 mins (10 mins each) RGB for the core so its not going to set the world on fire but it was 'interesting' combining data from different scopes and cameras and making it all fit together. Managed to grab 15 mins in between showers tonight. Most of the data is from a ED80 and Atik 460 mono and a wee bit from a Takahashi 106 and Atik 16200 (just for the core). Processed entirely in Pixinsight.
