My mistake KAF bin1 (12.4.2015), 1600 bin2 (30.4.2016). Now is to late for new image! At first clear night I will capture 180 sec!
RAW: NGC6888, 900sec
I am FAR from an expert, but I don't see much amp glow on this.
Am I just confusing amp glow for Nebulosity? I was looking at Astrobin and comparing this with other h-alpha examples and this single exposure is looking pretty good.
I hate to keep asking question and being picky about this, but this is a lot of money for me and I'd like to spend my money as wisely as possible. This despite the amp glow seems to be one of the better choices I have.
