Description

I deceided to add new data to some summer 2014 exposures ...

2014 : 25 x 600 s

2015 : 35x 900 s

FWHM : measured in Pixinsight : 2.3 arcsec (before deconvolution)

Limiting magnitude : 22.7 (with SNR=5)

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 galaxy

- residual sky background substraction

- color saturation boost

- green neutral

- TGV denoise

- slight deconvolution

- non linear image creation

Final image :

- jpeg calibration done in Mac Photo
