Messier 109 is a Barred Spiral Galaxy that can be spotted next to Phecda, the sixth brightest star in Ursa Major. It's most notable feature is the long bar going through it's core that resembles Darth Vader's Tie Advance star fighter from Star Wars. Nearby in this image are many other more distant galaxies and a few that are satellite galaxies in the M109 Group.

Phecda (outside of frame) is glowing quite brightly from the upper left corner but there can be seen diffraction spikes that just happened to be lined up in such a way that make this image also resemble the Bat Signal or some form of galactic spotlight.

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.
