Spiral Galaxy NGC 5033 in Virgo

This is a 30 minute exposure with an STL-1301E CCD camera thru Kopernik's 20-inch Ritchey Chretien Cassegrain telescope working at F/5.3. The field of view is about 19.5x25 arc minutes, with North at the top.

Dreyer's description from his New General Catalog (NGC):

"Very bright, pretty large, extended 167°, abruptly much brighter middle very bright nucleus, star northwest."

Spiral Galaxy NGC 5033 is a member of the Virgo galaxy cluster. It has a small, very bright, but diffuse nucleus in a bright bulge that is an X-ray source and shows a spectrum of a Seyfert Type I active nucleus. (Also see our M-77 page for more on Seyfert galaxies.) The inner bulge has a spiral pattern of dark lanes. There are several thin spiral arms with branches. The arms are lined by many small H-II regions of star formation.
