Thanks Dave,
Very happy how this one processed
Conditions were not good at all
I dropped back to 2 minute subs on this bigger and brighter target compared to using 3 minute subs on M17 the week before. From the data I found this to be a better choice and didn’t lose to much fine detail , definitely less gradient too.
On the camera side of things I’ve gone back to the Ascom preset of Gain 100 instead of a manual setting of Gain 101. I’m not sure if Gain 101 picks up the HGC that ZWO designed into the camera for high DR and low read noise. I guess we just have to trust them on this one. I only changed to Gain 101 as I read a post on CN from a guy who didn’t trust ZWO and decided to bump the gain up a notch to 101 or 102.

Cheers
Martin
