2nd nights : AO + ONAG (on axis guiding)

Pre-processing done in Pixinsight :
- overscan area offset correction
- bias correction
- dark correction using 7 x 1800 s darks
- flat correction
- hot pixel correction
- debayer
- registration
- stack
- crop
Processing done in Pixinsight :
- backgroung color neutralisation
- color calibration using galaxy
- careful sky background removal (DBE in PI)
- slight deconvolution
- non linear image creation
- color saturation boost masked
- green neutral
- TGV denoise (no mask)
Final image :
- jpeg calibration done in Mac Photo (levels adjust and further saturation boost and color balance)
