Description

This was a very difficult small target and after processing the initial set of 60s lights, I wasn't picking up much if any of the outer shell and really not appreciating any detail at all.  After going back and shooting at 180 seconds and 300 seconds, I tried to integrate all using WBPP in PI, only to learn that integrating images from different cameras and different sensor sizes is problematic in WBPP.  The 60s and 180s were taken with a modified Canon 80D, but the 300s images were obtained with a Canon 90D while the 80D out for repairs.  

This particular first draft, then, is just with the 60s and 180s images; I am going to have to go back and process step by step using Star Alignment followed by ImageIntegration to see if I can process all 3 data points together.
