I always get asked why I keep my exposures in narrowband down to 3 minutes. So I decided to compare 3 minute exposures to 10 minute exposures. This test was performed with my ZWO ASI1600MM-cool camera (CMOS) chip. The outcome may have been completely different had I tested with a CCD camera. And thanks to Trevor Jones for his shout-out on his AstroBackyard website.
