Thought I’d share my first image in a while! NGC 6823 has sooo much going on and looks great in both RGB and Narrowband. I went for Foraxx here, with RGB stars. Desperately needed more O3 - I lost 80% of my subs due to high haze. I had to stretch it within an inch of its life!
Taken at the awesome Roboscopes facility in spain on Pier 3 (ASA 12N). I am currently in the process of sending my Tak 160 there for hosting, the skies are FANTASTIC and the managed hosting service the guys there provide is world class. So much better than alternatives.
Processed in Pixinsight and Photoshop
Stars RGB.
Manual calibration - WBPP gets Bias wrong :)
DBE on each channel, SPCC, BXT / NXT / SXT. I created a synthetic lum channel from the Ha O3 and S2 and processed that using GHS and curves.
I then GHS’d each NB channel to get them popping as much as possible, and combined them in Foraxx. Added the Lum using LRGB combine.
Then off to Photoshop for a few levels tweaks and the brilliant filter Camera Raw Filter (CTRL + SHIFT + A on a new layer). So many amazing tweaks to be had here. Use opacity to decide how much of the filtered layer to keep.
120 second subs for NB, 60 second for RGB. 3nm Antlia filters.
