Thanks Kevin, Andy & Cam for your input. I will take everything on board and have another crack with the processing on this one.
Note to self- spend some time getting better polar alignment next night out as even these short 2 minute subs gave field rotation during the 70 minutes of lights. I had to de rotate during stacking to get rid of star trails in the corners.
Thanks again all for the advice. I appreciate it.
Bruce.
