Abell 194 Galaxy Cluster: Oct 21-28 Atoka, OK Same image as left but inverted in PhotoShop to reveal galaxies more clearly This stunning cluster contains approx. 4,700 galaxies within a 2-deg radius from center and over 10,000 at 4-deg. Chapman's cannonical study of A194 provides compelling data that the mean radial velocity is 5,396Km/s, given the Hubble constant of 65 Km/s/Mc, this indicates a distance of 265 MLY which is similar to the Perseus Cluster. I hate it when "sciencey" things are similar...makes me question the data. Most are available from the 2MASS and can be analyzed with the APMUKS, although they lack radial velocity data. There is considerable debate over what constitutes the "center" of this cluster but an average (Gaussian smoothing) appears to land near NGC 541 which is just fine by me for this is the iconic home of Minkowski's Object!.
