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
