Description

Hα: 9x 480" Bin1x1

[O III]: 9x 120" Bin2x2

[S II]: 9x 120" Bin2x2

I had to cut down exposures of [O III] and [S II] (and compensate binning the subframes) as the battery feeding the CCD was running out faster than expected.

I would like to reprocess it as my workflow has improved since, maybe someday. Or re-capture it with deeper exposures and better framing.

Banding on the lower right due to passing clouds.
