Description

Shot entirely in astronomical twilight at 195mm and f/7. Amazing what narrowband can do.

On the first two nights I put a Wratten #25 filter in front of my Duoband filter to allow only Ha to pass. Sort of a "poor man's" Ha filter. This caused some reflections around the major stars, so I stopped doing that.

Across both channels total of almost 15h integration time:

Ha - 11.0h (132x 300s)

O3 - 3.75h (45x 300s)

Processed in APP and PixInsight.

Original Revision: Modified HOO palette (R = Ha, G = 35% Ha + 65% O3, B = 20% Ha + 80% O3)..

Final Revision: Pure HOO palette.
