LRGB stack noisy, undersaturated
Most recent project involved about 2.5 hours of L on M51 and a little over an hour each of RGB. The resulting combined stack turned out very noisy and under-saturated. Increasing saturation in APP only highlighted the noise.
As far as I know I've used all of the default settings from calibration through integration. Attached file is linear, cropped and light pollution removal applied.
Suggestions appreciated as always!
Can you show a screenshot? I can only see an unstretched tiff I think
@vincent-mod Apologies for not seeing this response. I've attached a screenshot showing the cropped LRGB combine. Yes I can increase saturation from the tool to the right but that just comes out extremely grainy.
To be honest, that looks totally normal. 🙂 If you stretch more to reveal all the signal around the galaxy, there will always be noise going up as well. It will get better with more data for sure, but not completely gone.
