Description

First light with my new ZWO ASI 2600 MM Pro. Paired with Optolong SHO 3nm filters and a William Optics Zenithstar 73.Overall exposure is a bit wonky as my CEM25 seems to have died in the process if taking this picture:-24 x 180s Ha-24 x 180s Sii-5 x 180s Oiii (that's obviously when my mount died ...).
This was then processed in Pixinsight with a custom ratio for RGB channel assignment.
// R:
Ha * 0.8
// G:
Sii *.8 + Ha *.2
// B:
Oiii+ max(0,Oiii * 2 * (LumaMask-0.35)) + Sii *.2
Some curves, deconvolve for noise and star reduction, Dynamic Background Extraction and voila!
