The night I captured this image of this lovely little galaxy, the seeing was only ok, but the transparency was great. In fact, the transparency was so good from my backyard, that I didn't have to remove any gradient from the image, which is pretty unusual.

This galaxy has the brightness and symmetry of planetary nebula in our own galaxy, giving the impression of a colorful flower. The inner arms are bursting with blue O-B associations and red HII regions, quickly transitioning into a diffuse outer halo containing faint dust bands that extend out from the inner bright central regions of the galaxy. The central core is amazingly bright and stellar, from a no doubt busy black hole.

The galaxy is listed as being 39 million light years away and is roughly 2.4 arc minutes across. Its bright, at 10.8 magnitude, so the inner core should make a good target for visual observers, since its about the size of the ring nebula.

The total exposure is 32 minutes: four 8 minute live-stacks each of 240 two second subs with just an IR Cut filter.

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.
