Description

Only 9 x 1 min run. I was not able to stack another set of 5sec exposures in PI without introducing al lot of noise. Anyway there is no saturated stars, which was the reason for short exposures.

Pre-processing done in Pixinsight :

- overscan area offset correction

- bias correction

- flat correction

- hot pixel correction

- debayer

- registration

- stack

Processing done in Pixinsight :

- backgroung color neutralisation

- color calibration using cluster

- residual sky background substraction

- color saturation boost

- green neutral

- non linear image creation

Final image :

- jpeg calibration done in Mac Photo (dark pt adjust, denoise)
