NGC 7822 in Hubble Palette

I had this nebula on my mind for a long time, and the last session I got the chance to shoot it.

Initially I wanted to do a HaOIII Bicolor, but instead I went for a full hubble palette. This is my longest exposure to the date for a single, non-mosiac frame. It has roughly 12.5 hours worth of exposure in 5 min subs.

Narrowband:

Lens: Canon EF 200mm f2.8@f4

Camera: ASI 1600MMC @ Gain 139

Filters: Baader Ha, OIII, SII

Exposure: 47×5min SII, 54×5 min Ha; 48×5min OIII

Mount: Skywatcher HEQ5 Pro

Guide: Skywatcher 80/400 with ASI 120

Capture Software: N.I.N.A / PHD2

Processing: Photoshop / PI 1.8

Total exposure: 12.5 hours
