M63: The Sunflower in Canes Venatici

This is a small spiral galaxy 27 million light years away in the constellation Canes Venatici, where it resides in the sky as a member of the M51 group. This object is noted for having no bar structure and broken detail in 2 loose and flocculent spiral arms.

This is an active galaxy with a bright central nucleus. It is currently unknown whether this galaxy has a super massive black hole at the core, but if it does, the black hole is estimated to have a mass of (8.5±1.9)×10^8 M☉.

Though the flocculent arms only span 49,000 light years, this galaxy holds a prominent stellar halo extending out to 130,000 light years.

This object was very fun to capture. It had its troubles: imaging over four nights and through a nearly full moon, capturing bright and faint detail all in one, and getting 21.34 hours of LRGB data to cooperate. However, it was definitely worth it for a product that, despite many, many hours of frustration, I'm happy to share in the end.

The “AstroBin Image of the Day and Top Picks”, or IOTD/TP, is a long-running system to promote beautiful, interesting, peculiar, or otherwise amazing astrophotographs, with a focus on technical excellence. Learn more.

Submitted The date and time when you submitted this image for IOTD/TP consideration.	...
Views by Submitters (available since September 19th, 2023) Every image is assigned to 50% of available Submitters. In the event that at least 80% of them don't view the image before its time in the IOTD/TP process expires, it's assigned to the other 50% of Submitters and the process begins anew.
Promotions by Submitters When 3 distinct Submitters promote the image, it moves on to the next stage of the process: evaluation for Top Pick status. This requirement, in addition to anonymization of images and distribution to only a subset of them, prevents biases and ensures that the best images are selected.
Promotions by Reviewers When 3 distinct Reviewers promote the image, it moves on to the next stage of the process: evaluation for IOTD status.
Early dismissal Staff members have a lot of images to inspect on a daily basis, and they can dismiss images if they believe they don't meet the requirements for IOTD/TP selection. If an image is dismissed 5 times, it's removed from the process. This streamlines the process and ensures that any bias present in promotions could be overruled by other staff members.
