M90

I enjoy imaging galaxies and here we go again on the eve of galaxy season I just finished my attempt at M90 a prominent member of the Virgo Cluster. M90 lies about 59 million light years away in, you guessed it, Virgo. This is a large spiral measuring about 165,000 light years in diameter and containing an estimated 1 trillion stars. Those figues are similar to those corresponding to M31 the Andromeda Galaxy but the similarities seem to end there.

M90 has lost most of its interstellar medium and has very little in the way of active star formation other than near the core region. These facts make it the quintessential "anemic galaxy". It is thought this galaxy may be evolving into a lenticular galaxy. (credit messier-objects.com)

This was a fairly straight forward project that would benefit from more integration. I tried to keep it natural and bring out the outer halo which I think likely extends much further than it appears.

In any case, this one was a lot of fun to do and very nice to process.

I hope you like it and clear skies and good health to you all!

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.
