Crab Nebula (M1)

Crab Nebula (M1). I love this target, and I am really pleased with how well the image came out. Processing it was a thrill because it gave me the opportunity to scrutinize and appreciate this magnificent object. I was particularly surprised and delighted to see that these extreme colors--the threads and knots of bright reds and greens--are really in there, and didn't require extensive work to draw out. Imagine our ancestors seeing the origin of this supernova shining bright in the daytime sky in 1054! I couldn't resist making a few side-by-side comparisons--this 2024 version against my first attempt in 2021; my version against the Hubble Space Telescope's; and, most interesting to me--a comparison of a single frame on a clear night to a single frame on a smokey night (which I eventually discarded). Clear skies!

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.
