The Whirlpool Galaxy!

My first shot with my new iOptron 6 inch Ritchey-Chretien 1370mm f/9 telescope and new SkyWatcher EQ6R Pro mount!

77 X 300 second exposures for over 6 hours of total integration.

The Whirlpool Galaxy, or Messier 51 (M51), is a spectacular spiral galaxy located about 23 million light-years away in the constellation Canes Venatici. Comprised of two galaxies (M51A and M51B), it's known for its grand design, enhanced by a past close encounter between the two. The larger, M51A, is home to an active galactic nucleus, suggesting a supermassive black hole at its heart, and has a high rate of star formation due to the galaxies' interaction.

M51 was the first spiral galaxy ever identified, and due to its beauty, it is a favorite among amateur and professional astronomers alike.

In pop culture, M51 has been featured in various science fiction works. For instance, in Star Trek, the Whirlpool Galaxy is known as the "Pinwheel Galaxy" and is the location of Starbase 515.

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.
