17.5 inch scope with ST-9E CCD camera

 

Spiral Galaxy M74 (NGC 628), type Sc, in Pisces 

This conspicuous spiral is a prototype of a grand-design Sc galaxy. Its distance is about 30 to 40 million light years (R. Brent Tully's Nearby Galaxies Catalog has 32), and it recedes at 793 km/sec. Its spiral arms are about 1000 light years broad. M74's angular size is more than 10 minutes of arc in diameter which corresponds to roughly 95,000 light years actual size, or about the same size as our Milky Way galaxy. 

M74 is probably the chief member of a very small physical group of galaxies, which includes the peculiar SBa barred spiral NGC 660, the peculiar Sm galaxy UGC 891 (of a mixed type between spirals and irregulars), and the irregulars UGC 1176, UGC 1195, and UGCA 20.
