Description

I use the Hutech LPV4 filter on the nebula because the moon was present the first part of the night. The SQM was 19,8 at the begining of the nights and stabilize around 21,2 in the morning. On average : 20.5

The FWHM of the sars was not so good, 2.9 on average , so I use deconvolution to recover sharp stars

Pre-processing done in Pixinsight :
- overscan area offset correction
- bias correction
- dark correction using 7 x 1800 s darks
- flat correction
- hot pixel correction
- debayer
- registration
- stack
Processing done in Pixinsight :
- backgroung color neutralisation
- color calibration using nebula
- deconvolution
- non linear image creation
- color saturation boost masked
- SCNR noise reduction
- TGV denoise (no mask)
Final image :
- jpeg calibration done in Mac Photo (levels adjust and further saturation boost)
