Description

After long time of waiting for clear skies, this is my first attempt of deep sky photografie this year.

Final : Improved image processing

M42 is a delicate target !

In my normal workflow I do basic image processing in Fitswork, following image enhancements in PS.
This involves image conversion from fits to tiff and then jpg
Because of the high dynamic range of M42 , the central 4 young stars are overblown and cannot be seperated anymore when going the route through tiff.

B) So I did a different processing approach and used only Fitswork :
- basic processing
- deconvolution
- nebulosity background enhancement
- Gauss sharpening (mild)
- final image direct fits to jpg

C ) Further, more sophisticated, processing :

- "Super L" processing" (more subtle details in Luminosity)
- Wavelet processing 0.01 ( denoise)
- Histogramm optimization

D, Final ) added Luminanz 30 Subs. bin 2 x 2
thanks for watching
