Description |
||||
NGC 2090 is one of the smaller galaxies we have had the pleasure to image -- Wiki lists it at 2.4 x 4.9', though it appears somewhat larger when fully "stretched" to show those dim arms. This galaxy was studied as part of the HST Extragalactic Distance Scale Key Project, to help better define the value of the Hubble constant. 34 Cepheids were found within 2090. (The project looked at 18 galaxies total with redshifts to 1500 km/sec -- 2090 was one of the chosen few due to its spiral arms -- sparse enough to be resolved into stars with the HST.)
