Blue Mountain Vista Observatory New RInggold PA
NGC 925 (PGC 9332, MCG 5-6-45) is a magnitude 10.9 barred spiral galaxy in the constellation
Triangulum, about 45 million light-years away. Delicate spiral arms extend outward from the
central bar. Older yellowish suns dominate the central bar, while blue-white (young) star
clusters and red hydrogen emission nebulae make up the spiral arms. Faint galaxies in the
shot include the two at the left (East) side, which are in the 17th mag range.
