Description

I use the Hutech LPV4 filter to boost teh Ha and O3 lines. However, I got most of the signal in the red and I was not able to display information in the green and blue channel. I guess for that you need NB imaging ?

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
- non linear image creation
- color saturation boost masked
- TGV denoise (no mask)
Final image :
- jpeg calibration done in Mac Photo (levels adjust and further saturation boost)
