Description

Another one from the huge pile of targets from the spring. Wrestled with what data sets I had to make a processable image. Finally used 7 hours out of 10, of which DSS threw out another hour. Was shot at multiple angles which meant gradients all over the place, which I never got rid of completely as I lost the faint tidal detail if I cleared the noise. Also got rings on the big stars on the galaxy. However this was the third attempt at processing this data, the previous two being assassinated by cats and kids, so just wanted it done, warts, noise and all. Will go back sometime and process the individual sets and layer them......maybe.
