SPX350 F4.5, ATK-16HR, Baader RGB, Astrodon - Ha5nm, O3 3nm.

Always wanted a go at this 12.6 mag planetary with a central star at 14.1 mag. A perfect torus shape and a small outer halo with a lovely Milkyway field.

Ha O3 mapped colour blended with RGB. The Ha O3 mapped gave very good star colour but the RGB blend addition made it prettier.

Ha-red, O3-blue, Ha30%O3 70%-synthetic green

Ha-12x10min
O3-18x10min.
RGB 10x3min each.

Thanks for looking, John.
