The Whirlpool Galaxy

The Whirlpool Galaxy is one of the most spectacular sights when observing the night sky. Located at about 31 million years from us, it is a grand design spiral galaxy interacting with another one, in a slow dance by which both will merge within several million years. This image was built on top of my previous one (M51 - The Whirlpool Galaxy ( Andre Vilhena ) - AstroBin) by adding Ha taken this year and reprocessing using newer techniques. As a result, this rendition looks better to me, with better color contrast, more details and more depth and I am quite pleased with it.

On a side note, revision C is a crop of several yellowish smudges can be found near the brightest star in the image - HD117818. What are these? It is no less than a galaxy cluster located at about 2.4 billion years, meaning the light we see today left the cluster that long ago. By that time, life on Earth consisted of microscopic organisms in the sea and oxygen was just beginning the build up in the atmosphere.

Hope you enjoy!

Shot at Santa Susana, Portugal on the 29th and 30th of April, 2022 and at Barcarena, Portugal on the 24th, 25th, 26th and 27th of January 2023.

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.
