M27 Dumbbell Nebula - HOO + S
Photo description / processing
M27 Dumbbell Nebula - HOO + S
Captured in Moscow in September-October 2026
I started imaging with an ASI585MC Pro with a Player One Ha+Oiii filter, then switched to a mono camera with the same sensor, QHY MiniCam 8M.
From the color stacks I extracted Ha and Oiii using NBExtractPI, which I then combined with separate Ha and Oiii stacks from the mono camera.
I combined all of this into the HOO palette and added separately colored sulfur via NBColourMapper and ImageBlend
The stars were taken from the color stack and processed with SPCC and PSCM
