NGC 6306 & NGC 6307

This object is a pair of spiral galaxies located 150 million light years away in the constellation of Draco at a declination of +61 degrees. I could not find anything written on this fascinating pair of objects.

NGC 6306 is a 13.7 magnitude edge-on galaxy is that spans 1 arc-minutes in our apparent view, which corresponds to an actual diameter of 50,000 light years. The designations I have seen assume that this is one galaxy. The core of this galaxy is really a mystery. Half of the core is reddish suggesting strong HII, while the other half is blue suggesting strong star formation. A dark dust band splits the core in two.

But, could this actually be 2 galaxies in the process of merging, ala the Antennae Galaxies? The edge-on perspective makes confirming this difficult. For now, I am assuming that this is a single galaxy with a really strange core.

NGC 6307 is a barred galaxy that is slightly larger than NGC 6306. I like the short arms that are forming at each end of the long bar.

The distance measurements indicate that these two galaxies are about the same distance from us. However, I see no sign of interaction between them.

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.
