Description

VERSION A : A snapshot of the decreasing SN in Messier 82 taken in darker sky in the SW of France.

VERSION B : I just added an animation between the 2 february and 4 april photo ...

The brightness of the SN is much less than on the previous photo dated 2nd of February 2014.

I plan to take some measurements of the magnitude

FWHM : measured in Pixinsight : 3.2 arcsec (before deconvolution)

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

- slight deconvolution

- green neutral

- color saturation boost

- non linear image creation

Final image :

- jpeg calibration done in Mac Photo
