How do I determine the gamma neutral point for a ZWO ASI178MC?
Posted: Sat Dec 02, 2017 1:05 am
I noticed SharpCap sets my gamma to "50" by default in "Image Controls". When I read the SharpCap documentation, it was pretty clear that neutral gamma is "1", but it seems like other astrophotographers swear that is not the case and neutral gamma is closer to 40 or 50.
Can I go with "1" being neutral gamma and if not, how do I determine neutral for my setup? I am assuming I want my gamma to be neutral during acquisition so I can pull the most detail out. In this case, a bright galaxy like NGC6946, the Fireworks Galaxy. I have a terrible mount, so I am doing 15s exposures with the gain set at 250. This is on an 8" SCT with an f/6.3 reducer.
If neutral gamma is not where I actually want to be, how do I determine the best gamma setting?
Thank you!
