SHO Rosette CI

first Collaborative Image (CI)
data from :
Ha: jonnybravo0311, DennisOrion, ibuprofen200mg, kungfood (R channel) total 46.6 hr
Sii: jonnybravo0311, DennisOrion, ibuprofen200mg 19 hr
Oiii: jonnybravo0311, DennisOrion, ibuprofen200mg, kungfood (average G, B) 47.8 hr

processed in PixInsight by Norman Hey
each stack registered to masters by jonnybravo0311 then integrated with average combination, normalizaton additive with scaling, weights PSF signal weight, pedestal subtracted, no pixel rejection
each stack: dynamic crop, ABE, deconvolution Sii, Oiii MLT noise reduction prior to deconvolution; luminance mask applied in deconvolution (not for Ha stack)
linear fit Ha and Oiii to Sii then assigned each to simple SHO palette in PixelMath (R=Sii, G= Ha, B= Oiii)
