NGC 6927, NGC 6928 and NGC 6930

This image captures an obscure trio of three NGC spiral galaxies in the constellation of Delphinus at a declination of +10 degrees. All three galaxies are about 200 million light years away.

The largest galaxy is the central one, NGC 6928. This near edge-on galaxy spans 1.5 arc-minutes in our apparent view, which corresponds to an actual diameter of 90,000 light years. I love galaxies at this orientation, where I feel that I can peer in just over the edge of the disk. This galaxy has a fascinating structure, with an offset core, two bright arm extensions, and a wide outer disk dust region.

The galaxy at lower left, NGC 6930, is also nearly edge-on and is also fascinating. The disk has short stubby arms which terminate quickly. At the upper end of the disk, a small orange galaxy (PGC 200365) is seen. Is this a companion? If so, NGC 6930 does not seem too disturbed by it.

The smaller galaxy NGC 6927 is on the right side. Many other galaxies are visible in the background.

Several interesting star asterisms are visible throughout the background, including lines, arcs, Vs, and circles. Or perhaps my imagination is just especially active as I write this.

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.
