M51 - The Whirlpool Galaxy in RGB (OSC)

M51, also known as the Wihrlpool Galaxy, is a classic spiral galaxy located 31 million light years away from Earth, located within the Canes Venatici constellation. It is interacting with its companion galaxy, NGC5195, which is passing behind M51 from our perspective. It is the first galaxy to be classified as a spiral galaxy and is thought to contain 160 billion stars.

This image is one of number of successes using my Edge HD OTA in the last month. I initially got stuck trying to image with the scope back in 2020 and gave up, running back to my small refractor! I decided to give it another go this year and had better luck. My mount (and guidescope!) is not quite good enough to guide the Edge at F/10 and, along with iffy collimation, explains the star shapes, but I am happy to get something half decent!

Thanks for looking!

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.
