Messier 100 (also known as NGC 4321) is a grand design intermediate spiral galaxy located in the constellation Coma Berenices. It is one of the brightest and largest galaxies in the Virgo Cluster, located approximately 55 million light-years distant from Earth and has a diameter of 107,000 light-years (Wikipedia). NGC 4312, the second-largest galaxy in the frame, is an edge-on spiral galaxy also located about 55 million light-years away NGC 4312 is a member of the Virgo Cluster and is a LINER galaxy that has undergone ram-pressure stripping in the past. I like the prominent dust lane visible in its disc. Unusually good seeing throughout the shoot allowed the depiction of quite a bit of fine detail. I planned on adding Ha, but I ran out of time, as the galaxy hits the tree line at midnight and astro dark commences after 10:00. This combined with poor weather forecasted over the next week, then the growing Moon pushes the next broadband imaging three weeks out. I only need an hour or two more green, I know, but it seems like a long time to wait for very little.

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.
