IC 2574 in HaR OiiiG OiiiB, William Optics Redcat 51, ASI1600mm Pro at Bin1, -20C: RGB subframes of 60″, Ha and Oiii subframes of 180″

Ha is used as integration of R channel, Oiii as integration of G and B channel by PixelMath, PixInSight.

IC 2574 (Coddington’s Nebula) – Intermediate Spiral(SABm) Galaxy in Ursa Major, an intermediate Spiral(SABm) Galaxy in the Ursa Major constellation, situated at about 17.000 Ly from us, appears close to the northern celestial pole and, as such, it is visible for most part of the year from the northern hemisphere.

It is an outlying member of the M81 Group and is currently forming stars; a UV analysis showed clumps of star formation 85 to 500 light-years (26 to 150 pc) in size.

IC348 SHO Dynamic Narrowband Combination

According to Andre B. [ https://telescope.live/blog/dynamic-narrowband-combinations-pixelmath ] who in turns referred to The Coldest Night [ https://thecoldestnights.com/2020/06/pixinsight-dynamic-narrowband-combinations-with-pixelmath/ ] narrowband channels integration and combination is subjective and could not coincide with a simple channel combination of Sii Ha and Oiii masters within an RGB implementation, as also suggested by Edoardo Luca Radice during CEDIC 2019; cfr. “Creating near true color images for nebulae from narrow band data using PixInsight” [ http://www.arciereceleste.it/tutorial-pixinsight/cat-tutorial-eng/110-cedic19-art?fbclid=IwAR0ybmyfZCC8G2ykfgDavTpBY7tEjE_DhJOAeT_QM5gZpKSvAfSmiNOoznw ]

In my approach and attempt I used PixInSight > Pixelmath formula

R = (Oiii^~Oiii)Sii + ~(Oiii^~Oiii)Ha
G = ((OiiiHa)^~(OiiiHa))Ha + ~((OiiiHa)^~(OiiiHa))Oiii
B = Oiii

to generate IC348 integration and postproduction.
