NGC 5972 (2014)

I can’t explain this because it’s too weird. I saw the image processed at this article and decided I wanted to try processing away some of those cosmic rays. Anyway, read that blog entry if you want to know more about it.

I spread the filters across the channels slightly to give it a more balanced look but [O III] is still represented by blue and Halpha is red.

The data is pretty noisy because it’s all medium and narrowband imagery. Can’t really be helped. Well, not without a bunch more orbits.

Giant Ionized Clouds Around Local AGN - Obscuration and History (HST Proposal 12525)

Red: WFC3/UVIS F763M + WFC3/UVIS F673N + WFC3/UVIS F621M
Green: WFC3/UVIS F621M + ACS/WFC F505N
Blue: ACS/WFC F505N

North is NOT up. I’m not actually sure which way is up. Sorry about that.
