M63 is a magnificent spiral galaxy located in the Northern constellation of Canes Venatici, about 30 million light years away. The galaxy is a member of the M51 group. There are lots of faint galaxies in the background.
M63, often called the Sunflower Galaxy because of its resemblance to that flower, is a spiral galaxy about 27 million lightyears away in the constellation of Canes Venatici. It is a member of the M51 group of galaxies.
I imaged my version of the galaxy from my back yard observatory in Nottingham, UK over the nights of 4th and 5th of May 2021. I used my TEC140 refractor and Atik 460 CCD camera with Astrodon LRGB filters. I used off-axis guiding on my MESU200 mount.
Integration is a total of nine hours comprised of:
Luminance > 30 x 300s binned 1×1 ; Red > 22 x 300s 1×1 ; Green > 24 x 300s 1×1 ; Blue > 24 x 300s 1×1 to give a total of about 8.5 hours of integration time. Captured with SGP pro and processed in PixInsight.
Annotated and inverted versions of the galaxy shown above. The annotated version shows the many, extremely distant background galaxies present in the image, some of which are billions of lightyears away.
The finder chart to the left shows the location of the galaxy.
