Description

My first mosaic and longest total integration time on a singe final image so far.

Frames 300" each:

Panel 1 (Heart Nebula):

Ha: 107

Oiii: 101

Sii: 101

subtotal: 309 x 300" = 25,75 h

Panel 2 (Soul Nebula):

Ha: 63

Oiii: 26

Sii: 31

subtotal: 120 x 300" = 10 h

Total integration time: 35,75 h

Processing:

Preprocessing using Blink, WBPP to calibrate, SFS to weight & select, ImageIntegration and DrizzleIntegration (Panel 1, Ha of Panel 2 only) for integrating.

Mosaic preparation:

For each panel Sii and Oiii:

Crop, DBE. TGV+MMT as needed to match the other panel in terms of noise.

For Ha panels:

Crop, DBE, Decon. TGV-MMT as needed.

Registering channels using StarAlignment (Register/Union Separate), combining with GradientMergeMosaic. Register all mosaics to Ha and crop.

Used Ha as luminance:

HT, Curves, LHE

HSO combination for RGB using Pixmath:

Stretch separate channels to non-linear using HT and Curves. Combine to pure HSO using PixMath. Background neutralization, HT, Curves, Convolute.

Combine RGB and L with LRGBCombination:

Multiple curves, Resample, StarReduction (A. Block Method using Ez Processing Suite), ACDNR, MMT
