IC 4592 - Blue Horsehead Nebula

My first LRGB and pretty happy with the result.

Despite the cold, humidity, slow polar alignment, issues with battery voltage, I got 1.5 hours of L and 50 minutes of RGB each.
Taken from a bortle 1 site 2 hours north of Perth.

SW HEQ5 pro
SW ED80
QHY OAG with ASI120MM mini
QHC CFW with 2" Optolong LRGB filters
QHY268M
Pegasus Powerbox Advance
NINA, PHD2, DSS and PS

Each sub was 5 minutes at gain 56 and offset 20 at -5 degrees.
I had to search online how to add the luminance.
