Revision title: M51 (Whirlpool Galaxy)

This image was the result of post processing 26 exposures taken at ISO 1600 for 5 minutes each with a 130mm refractor and 1.6 extender. The exposures were captured on the night of April 30, 2021 and the seeing wasn't good. My tracking was a bit off as scintillation was an issue. This image was cropped a lot. Dithering was used and flat frames, dark frames and bias frames were all used in Deep Sky Stacker to assemble the images. First post processing resulted in the galaxy being too saturated and this last attempt is a bit more toned down. I consider myself still a novice in the post processing phase since I'm only just now learning star maps, layer masking, etc.

Title: M51 (Whirlpool Galaxy)

Description: I decided to redo the post processing with a bit less aggressive techniques and came up with this image. I use fast telescopes and M51 is tiny on my Canon Ra camera sensor. So, I was happy to bring out some more structure in the galaxy in this final post processing phase.

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.
