Acquisition type: Lucky imaging

I keep reprocessing this set of data periodically since I finished capturing it back in June 2021 and just haven't happy with the result. I took another stab at it over the last couple of weeks and finally feel like its a decent representation of the source image data.

This lovely barred spiral (morphological type SBcd according to the SIMBAD database) has an exceptionally bright bar and its two primary arms are broken into multiple branches. There is lots of star forming activity in this galaxy given the blue and pink knotty appearance of all arms and their branches. Somehow, the galaxy gives the impression of being "small". Based on its estimated distance of somewhere between 83 and 97 million light years and its dimensions of 1.5 x 2.5 arc minutes, the galaxy is "only" 62,000 to 72,000 light years across - considerably smaller than our own galaxy.

The little edge on spiral galaxy PGC 60007 is considerably further in the background at around 400,000 light years, so the two galaxies are not related, just happening to fall along roughly the same line of sight. With its dark dust lane, it looks like a miniature version of NGC 4565! It appears to be on the larger size, at around 140,000 light years across.

Each of the 23 images stacked to produce this image was a live-stacked image (using SharpCap) of 320 x 1.5 second exposures.

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.
