Description

I could not remember if I used a LPV4 filter for this object ... I will have to investigate :
The LPS-V4 filter was definitely in place ...

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 stars
- residual sky background substraction
- color saturation boost (in the red part only)
- green neutral
- erosion
- non linear image creation
Final image :
- jpeg calibration done in Mac Photo including slight "Definition" enhancement
