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
