RGB data comes from the data acquired with the MN152 Mak-Newt 2020-03-27.

M90 is the dominant galaxy in this image - a Seyfert type two classed as SAB(rs)ab. The full size image has an image scale of 0.76 arcsec/pixel. M90 is one of the members of the Virgo cluster and is located in the constellation of Virgo. Immediately to its right is IC3583, a dwarf irregular galaxy. The two galaxies supposedly constitute a pair with M90 being dominant and IC3583 a satellite. Some have disputed an interaction between the two - mainly because the estimated distance of M90 has a wide variance from 37 to 60 million light years. Also, M90 has the unusual characteristic of a negative redshift (meaning it is actually blue shifted). IC3583 has a normal redshift relative to its independent distance estimate. These objects and some of the brighter stars are identified in the annotated image.

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.
