Although these galaxies appear close, they are actually quite far apart. NGC 4725 is the closest galaxy at 40 million light-years away and happens to be the smaller one even though it appears larger. It is a barred spiral galaxy over 100 thousand light-years across. Interestingly, the galaxy only has one large arm that makes 2-1/2 revolutions around the core. The arm has many prominent blue regions indicating newborn star clusters. The smaller galaxy, NGC 4712, is larger than NGC 4725 in actual size at 150,000 light-years across but is over 200 million light-years away. I decided to image this by doing a random search on Stellarium and thought it would make a good project with my C8. Ironically, I found many other people that I follow also doing this object - great minds think alike.

There appears to be many smaller galaxies in this Field of View which is not surprising given the location in the constellation of Coma Berenices, a region of space rich in galaxies. NGC 4725 had a surprising amount of detail as did NGC 4712. The central dust lanes are really quite visible and even the faint ones near the core. The colors were fairly easy to pull out without much adjustment, however, that made not going overboard with color saturation difficult especially for me since I tend to saturate to the fullest extent. With this in mind I held back and attempted not to oversaturate.

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.
