DETAILS: Imaged at f9 with a 12.5" RC Optical Systems Truss Telescope mounted on a Paramount ME Robotic mount, using an ST-10XME SBIG camera and Tru-Balance filters. LRGB:110:30:30:40 minutes. Luminance is unbinned. RGB: 40:40:40 minutes binned 2. Aligned in RegiStar, and processed in MaxIm DL and Photoshop. Luminance acquired 92304, and RGB on 101704.

COMMENTARY: The Crab Nebula is a supernova remnant of glowing gases and plasma expanding from a cataclysmic explosion of a star fifteen times more massive than our own sun. This supernova explosion was observed and reported by Chinese astronomers in 1054 A.D. Being relatively close, 6,500 light-years, and so massive an explosion, it shone as bright as Venus in the daytime sky for 23 days. The Crab Nebula is located in the Constellation Taurus, and at its center is a rapidly-spinning, city-sized neutron star as massive as the sun. It is a spectacular object to image in color. High-speed winds and shock waves fill the turbulent inner region, as bright wisps expand at half the speed of light. The neutron star (pulsar) generates huge electrical voltages that accelerate matter and anti-matter particles outward along its equator, and create the shock waves.

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.
