Crab nebula M1 in SHO (Mohammed Dawoud)

Crab nebula M1 in SHO

This is a reprocessing of my data taken back in 2022.
This nebula is called crab nebula M1. It’s located about 6,500 light years from us and 11 light years in diameter. The nebula is in Taurus constellation. It’s a supernova remanent that witnessed first by Chinese astronomers in 1054 AD and it was seen during day for 23 days and could be seen by the naked eye for 2 years at night. The supernova is happening when a giant star (at least 9 times our Sun in size) uses all its nuclear fuel, and collapse in huge explosion. The supernova remnants are the expelled gases of the died star. These gases are expanding in a rate of 1,500 km/s. In the middle of this nebula, there is a high energetic small star produced from the explosion called Neutron star (Pulsar). It’s only 30 km in diameter and spins at about 30 times per second to form a high energy Gamma radiation that ionize the remaining gases to emit colorful lights. The is color mapped to SHO Hubble palette. Gear setup: Celestron HD8 @f/7, iOptron GEM 45 guided by Celestron OAG + ZWO 174 MM, ZWO 1600MM @ 0, Baader narrowband 6nm SHO filters, Bin2x2, Lights Ha 24 x 300, Oiii 24 x 300, Sii 18 x 300, Darks 10, Flats 20 per filter, Bias 50. Total exposure 5.5 hours. Captured by APT. Processed in PI & PS.

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.
