Description

I learned quite a lot through this experience. Integration time is king; however, I also learned that longer exposure times, specifically on a target such as this, will provide greater faint detail than a higher number of shorter exposure times. I shot multiple nights with durations ranging from 30" to 180" and stacked in different configurations but similar integration times of around 4 hours. The stacks with the 180" exposures gave the most faint details.

70x180"

133x120"

220x60"

Total Integration = 11.6 hours
