Description

One of the easiest targets I have processed, the image just seemed to come together without any major issues. I spend more time to try different contrast options than actually processing the image. And at the end trying to find a pleasing level for a subtle noise reduction. Here is what I did after the masters were created;

- DynamicCrop
- DBE (not sure if this was even needed but I did just in case)
- Deconvolution
- LinearFit
- ChannelCombination
- SNRC
- A couple of curves adjustments to adjust brightness and contrast
- A few different color masks to balance & saturate them separately
- MorfologicalTransformation to tone down a bit the star sizes
- And finally a very modest (level -7 edge protection) TGVDenoise tor chrominance

Thanks,

- Mikko
