caught NGC 4274 (Halifax)

BGO collected photons from NGC 4274. A galaxy in Coma Berenices. One of the RASC Finest NGCs as well as a Herschel 400 target. I had first viewed this interesting galaxy on 4 Jul '16.

RASC Finest NGC 4274 in luminance

Luminance only, 60 seconds subexposures, 10 stacked shots. FITS Liberator, GIMP. North is up; east is left.

It features a bright condensed core with some nearby dark elements. It is surrounded by bright ring. And then there's a very large diffuse disc beyond. Very interesting.

I think there's something north-north-west of the galaxy but nothing is noted in SkyTools 3 Professional. There's a very soft diffuse brightening. SIMBAD and AladinLite show it is LEDA 213976.

South-south-west of the big spiral is a small, faint oval, LEDA 213975.

Also, nearly due east of the 4274, near the edge of the image, is a bright but small round fuzzy. Not marked in the software. SIMBAD and AladinLite note this is a "GiC" or a "Galaxy in Cluster of Galaxies," specifically 2MASX J12203217+2938184.


Imaged again on 12 May '18.
