M1, Crab Nebula

This iconic object has been on my wish list for some time, but for sure it deserves more FL than 800mm. I had to crop this image a lot to achieve an acceptable FOW.

This object is a supernova remnant observed by chinese, japanese, arabic and native american astronomers 1054, when it appeared and was visible for 653 days. It was in 1731, when John Bevis discovered what we know today as Messier 1.

27 years later, Charles Messier hunting for Haleys Comet, knew nothing about Bevis' discovery. He observed a faint blob, believing that this could be the comet. But soon he noticed, that there was no movement against the starry background. It never could be the comet he was looking for. In order to avoid this mistake again, he noted the objects position. It was the first entry in what was to become the famous Messier catalogue.

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.
