Description

This image was acquired over 2 night (26 & 31 july 2014)

The FWHM is 2.2 arcsec measurd in Pixinsight (on the raw stack)

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

- multiscale dynamic compression

- non linear image creation

- erosion

Final image :

- jpeg calibration done in Mac Photo

For version C and D :

- added slight deconvolution on linear image in PI

- performed masked High Dynamic Compression to protect low levels in PI

- fine tune non linear transform with Curves Transform in PI

C : erosion filter in PI

D : no erosion filter
