Hi everyone,
last night despite the heat got SII of the NGC3372 to try the HST palette with my previous bi-color image.
I used Ha as a Luminescence channel.... not sure if it 's beneficial.
Total 5h50m, ED80 with CCDT67 @ 0.75x 314L+ Ha and OIII @ min10C
SII is at min5C with the help of Jaycar's freezer spray. Was a warm night
