Sunflower Galaxy M63

This is the galactic flower M63 a.k.a. the Sunflower Galaxy. It’s approximately 27 million light-years from Earth located in Canes Venatici. It’s 100,000 light-years in diameter, which is about the same size as the Milky Way. What’s interesting about M63 is that it’s a flocculent spiral galaxy where the spiral arms are patchy or fragmented unlike a grand spiral galaxy. About 30% of spiral galaxies are flocculent, 10% are grand design, and the rest considered “multi-arm”.

FYI flocculent means “having or resembling tufts of wool” and a synonym is fluffy. The Milky Way is considered a flocculent galaxy, so I guess we’re fluffy!

This is an HaRGB image where we combined both broadband and narrowband data taken with our OSC camera. Our telescope is not ideal for capturing galaxies, but we managed to drizzle data to get a clear enough picture that we’re happy with.

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.
