Here is my Whirlpool Galaxy.
This image is particularly special for me because it represents the culmination of a particular effort in my life.
I founded the Mount Lemmon SkyCenter for the University of Arizona and created a new destination for astronomy programs in the US.
One facet of the programs included astrophotography (obviously). An image like this is the cumulation of years of dialing in a telescope in order to produce optimal imagery.

I processed this data using all of the latest and greatest tools available (DBE. Local Normalization, SPCC, xXT, etc).

I would recommend scrolling around to see the background Universe as well as diving into the Whirlpool.... just make certain you don't go into to far...

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.
