IC 302 is a low surface brightness spiral in eastern Cetus. It's distance is a bit vague. Redshift puts it at 261 million light-years but the median of one set of Tully-Fisher measurements say 181 million light-years while the average says 194 million light-years. The redshift distance is likely severely compromised by its motion through space as it implies a size of 176,500 light-years. Quite a large value for a low surface brightness galaxy. The Tully-Fisher measurements imply a size of 122,000 to 131,000 light-years. Still large but at least in the reasonable range.
NED and Seligman classify it as SB(rs)bc. The bar is obvious. The northern arm coming from the ring is well defined with lots of star clouds. The southern arm is quite fuzzy and rather straight. One paper (
http://iopscience.iop.org/article/10.1086/521358/pdf ) describes this galaxy as: "From the global distribution of optical_light, this galaxy appears asymmetric. Our images show an apparently multiple set of faint southern arms and a strong southern dust lane. The red central region, including the bar, and the bluer ring and arms are emphasized in the B-I color index map."
This galaxy somehow managed to escape detection until Stephane Javelle found it on December 15, 1892. Yet another image compromised by poor seeing and transparency. Pretty much the norm unfortunately. NED had nothing much on the field so no annotated image this time.
