M88 and M91

Along with M85, imaged on the same night, these were the last two Messier objects in the Virgo Cluster of galaxies I was able to image. I am looking forward to shooting other objects such as nebula and clusters again.

M88 (a.k.a. NGC 4501) is a spiral galaxy about 50 to 60 million light-away in the constellation Coma Berenices. It is one of the fifteen Messier objects that belong to the Virgo Cluster of galaxies. Interestingly, M88 seems to be on an elliptical orbit that is carrying it toward the cluster center, which is occupied by the giant elliptical galaxy M87. M91 (a.k.a. NGC 4548 ) is a barred spiral galaxy located also in the Coma Berenices constellation and is about 63 million light-years away from the earth.

Processing this image proved more difficult as the subtraction method that I have been using on most of the other Virgo galaxies was giving me good results so I went back to Gradient Exterminator to remove the gradients and some of the noise. M88 and M91 represent the 83rd the 84th Messier Object I have captured.

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.
