Description

Since two years I am struggling to process the Ring Nebulae image. I dont know how to display correctly the nice saturated color of the nebula (image B) and at the same time the extensions (image A).

The frames at FD = 10 are just background limited at 1200 s with the LPV4 filter.

Pre-processing done in Pixinsight :

- overscan area offset correction

- bias correction

- flat correction

- hot pixel correction

- debayer

- registration

- stack

Processing done in Pixinsight :

- color calibration using stars

- residual sky background substraction

- green neutral

- slight deconvolution

- cosmetic correction of satuated pixel in the ring nebuale

- converted to non linear image

- the nebulae was corrected using curves transformation

- color sat applied

- blue adjusted

Final image :

- jpeg calibration done in Mac Photo
