The Sunflower Galaxy

Spiral Galaxy in Canes Venatici

Uploaded 4/1/2001

This beautiful inclined spiral in Canes Venatici is a complex multi armed system, with a very bright core that is always burned out pure white on film shots, to bring out the faint spiral arms. With CCD, and applying DDP to the image, this can be corrected. M63 is 9.3rd magnitude and a size of 14x7 which is much larger than my 10 min wide field seen here. This galaxy has a very yellow core as clearly illustrated in the Wray Color Atlas of Galaxies and very subtle blue arms with a number of small pink HII regions dotting the arms. Just halfway into the field on the right edge is an edge on spiral, A 15th mag galaxy.
