UGC 6309 (Gary Imm)

UGC 6309

Everyone has a corporate sponsor these days. Meet the latest DSO sponsored by Lexus!

This Astrobin Debut Object shaped like a Lexus logo is a beautiful barred spiral galaxy located 130 million light years away in the constellation of Ursa Major at a declination of +51 degrees. It is a magnitude 13 galaxy whose bright ring spans 1.3 arc-minutes in our apparent view. This corresponds to a diameter of 50,000 light years.

I love the contrast between the yellow core and the blue arms. A touch of HII is seen in the upper half of the disk. The arm structure looks like an inner ring although it is asymmetric, likely due to some disturbance in its past. I am surprised by the lack of a visible outer disk, as well as the star stream arc which extends above the object.

I also like the 5 blue and orange galaxies and stars lined up beneath UGC 6309.

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.
