The Crab Nebula (M1) in SHO

This interesting and well documented supernova remnant, located about 6500 light years from Earth, is always interesting to image. I like the story that the supernova was observed already in 1054 by the Chinese. It looks very different in different wavelengths. Visually, by looking through a telescope, it looks mostly grey and fuzzy, and also so in many RGB images. In narrowband much more details are seen. My favorite is the Chandra X-ray image, showing some really interesting structure around the pulsar inside the nebula.

The nebula is a bit small for my telescope, but still I tried to image it in late January 2022. Most images are from January 17, but some are from January 20, 28 and 30. I struggled with poor weather so I only got a small collection of 5 minute exposures in SII (10), H-alpha (16) and OIII (16). I think I got some nice details.

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.
