Hi,

This is Iris nebula (NGC 7023 from Cepheus) trough my set-u for astrophotography: MN190 (mak-newt) on EQ6 belt-drive, ASI ZWO 533MC as main camera and QHY5II-L mono as guiding camera (OAG). The result is a stack of 41 exposures, 5 min each, from a Bortle 5 zone. Is amazing how CMOS camera and especially this one can work on a light polluted sky in full broadband.

Acquisition, calibration with dark, flat and bias, debayering and stack - MaximDL, background neutralization, Photometric Color Calibration, ABE, SCNR, MMT, Histogram Transformation - in Pixinsight, Contrast, star reduction with 2 pixels and a bit of extra-denoise - in StarTools.
