Description

This is a new version of the late 2019 image, with new data acquired in January 2020.

With roughly twice total exposure time, and some Ha subs.

The processing has evolved a little during the mean time also.

I have included (original version) an animation with the initial image for comparison purpose.

Note that 30 L subs & 8 R subs were taken at gain 139.

Processing in PI

- Dark & Flat calibration of L, R, G, B & Ha channels

- Cosmetic Correction

- Registration

- Integration

- Crop all channels

- DBE each channel to prepare sup lum integration.

- Create Super Lum channel by integrating L, R, G, B channels with noise weighting

- Mure Denoise SL

- MultiScaleLinTrans kFiltering

- RGB creation

- Ha RGB creation using NBRGB

- Delinearisation using HT for SupLum and MS for RGBHa

- Combine SupLum with a & b color channels of RGBHa

- Color saturation (and desaturate bkg)

- TGV denoise

- Unsharp mask

- Color Sat under star mask

In Mac Photo : sat, levels, deflip
