Description

This is surprisingly faint. Previously I've only imaged bright narrowband objects where the signal comes through very quickly. Here, perhaps in part due to my 7nm filters and light pollution the data came in very slowly, especially in Oiii. I had 6 nights of nearly clear weather with lots of moon. I just left everything running, and  culled about 25% of my subs due to cloud. The last night was spent evening up the 2 panels and the filters to try and have equal amounts of data everywhere.
