I consider this my best attempt thus far at M51. It is not perfect and never will be, however, I deemed it sufficiently good to post here. Keep in mind I've only been doing astrophotography for 2 months and scarce clear nights and in light pollution. However, this image was taken in the rural peripheries of the Northern Virginia metropolis.

Description: Same equipment and same exposure time. But this time it was at a dark sky site (low green or high purple I think). And I fixed some optical pinching that I had in my first image. Pardon the slight vignetting near the center. Other than that, it's a dark sky with round stars (well there's some slight coma, but I've seen much worse) and good galaxy detail. But I'll need more than 10-20 minutes of integrated exposure to pull out much more detail. Stay tuned. I do consider this a work-in-progress still.

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.
