Description

Original = SHO color mapping with Ha mixed in luminance

Rev. B = Tonemapped version

Data was 2x downsampled because I wasn't too happy with the star shape and sharpness at 1x1 bin.

User @Arvid Emtegren imaged the same region 2 days after I shot these frames and he found minor planets 52 Europa and 150 Nuwa cruising past this DSO. I confirmed their position in Stellarium, they corresponded to 2 streaks in my data that were not fully removed by sigma clipping.

Rev. C shows the minor planets moving down in the H-alpha frames, hot pixels are moving up (due to dithering).
