NGC925 was discovered (Sep 13, 1784) by William Herschel. NGC925 is a nearly face-on spiral galaxy in Triangulum. This galaxy is part of the Hubble Space Telescope Key Project on the Extragalactic Distance Scale, a long-term project dedicated to determining the Hubble constant to within +/- 10% using Cepheid variable stars as distance indicators. The Hubble constant defines the relationship between the distance of a galaxy and its recession velocity due to the expansion of the Universe.  Knowing this relationship more precisely will give us a more accurate measure of the age of the Universe. NGC 925 lies relatively nearby, with a redshift of z=0.0019, corresponding to a recession velocity of 550 km/sec.  Visually, NGC925 appears as a large, fuzzy oval with a gradual brightening toward the center.
Observation notes :   In my 18-inch at 250x I had difficulty getting a handle on the orientation of the brighter elongated central region and I observed a curious effect of the eye.  As I moved my eye about the field testing different averted vision positions the central area actually appeared to "flip."
