NGC281 in SHO narrowband palette, with Ha integrated as Luminance layer, as according to to Nik Szymanek approach to Sulphur-II Luminance Compositing.
Ha layer (luminosity blending) added in starless and stars separate layers.
SHO stunning integration

NGC281 in SHO palette, crop to focus about Pacman Nebula.
Deep reworking focused about colors and histogram stretching over integration obtained by several records in SHO narrowband by William Optics Redcat 51, ASI1600mm on EQM35 collected between 2021 and this year.

NGC281 integration by summing several records in SHO narrowband by William Optics Redcat 51, ASI1600mm on EQM35 collected between 2021 and this year.
According to to Nik Szymanek approach to Sulphur-II Luminance Compositing I added Ha band in starless cleaned version as luminance within Photoshop postprocessing flow.
