Description

I have added another 10 hours of OIII (total now 47 hours) data over the past couple weeks and reprocessed from the beginning with my data from last year. My goal is possibly pointless but over the next while, maybe year or two, I want to collect 100 hours of OIII on this target to attempt to bring out the most detail I can while keeping the image noise free, crisp, and contrasty. This maybe an exercise in futility but I am almost half way there, so just keep imaging on and see what the final result is. Am I way past the point of diminishing returns? We will see!
