Revision title: Galaxy, M51a and b, London Suburbs, Midsummer's Night Revision

M51a and b, Whirlpool Galaxy, approximately 27m ly away.

Even though it was somewhat overcast with a layer of thin high-level cloud last night, and we don't get to full astronomical darkness at this time of year, I am pretty happy with my capture of M51a/b on midsummer's night, from my light polluted back garden in the London suburbs.

A combination of 150 subs x 45 seconds each plus darks and flats. Guided Celestron Edge HD 8 on AVX Mount, ASI2600MCPro with Sharpcap, Astro Pixel Processor, PaintShop Pro and Topaz.

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.
