Description

The Sunflower Galaxy floats in the constellation Canes Venatici at a distance of about 30 million light-years from Earth.  It is commonly referred to as a flocculent galaxy due to the lack of well-defined spiral arms in visible light; however, near infrared images reveal a symmetric two arm structure.  The star streams are believed to be remnants of tidally disrupted satellite galaxies.

This was taken under my fuzzy skies of upstate NY.  Fortunately, M63 is bright enough to punch through the haze.  Processing was done in CCDStack and Photoshop.

Exposures were:
Luminance - 50 x 600s  (Bin 1)
Red - 13 x 480s (Bin 2)
Green - 15 x 480s (Bin 2)
Blue - 17x 480s (Bin 2)

Separate RGB were collected for the stars:
Red - 10 x 60s
Green - 10 x 75s
Blue - 10 x 85s

I hope you enjoy!
