M1 - The Crab Nebula

Link: http://kurt-zeppetello.blogspot.com/

Messier 1 (NGC 1952) or the Crab Nebula is a supernova remnant in the constellation Taurus and is approximately 6300 light years from us and 10 light years in diameter.

Chinese and Arab astronomers recorded the supernova event in the summer of 1054 in the constellation Taurus. They described it as a "guest star" that was brighter than Venus and visible in the daytime for several weeks. It is believed the Anasazi (native Americans in the southwest) recorded it in a wall painting in Chaco Canyon, New Mexico. The Crab Nebula has been identified as the remnant of this supernova - a massive star that collapsed after exhausting its supply of fuel nuclear resulting as a spectacular explosion. M1 is the outwardly expanding shell of ionized gas thrown off in this cataclysmic event (source: Fred Espanek, Astropixels.com).

I captured M1 over two nights and represents the 48th Messier Object I have taken, only 62 left. The final image has diffraction spikes (star crosses) on the larger stars while the original images have none. So did I get a new scope and shoot two separate images? NO! I added the spikes using the Photoshop Plugin - Astrophotography Tools. I did a lot of processing on these images as I develop my own technique. I was trying to follow Ian Norman from Lonely Speck and have used his method for removing the gradients in Lightroom but processing using his LRGB method was a bit overweening for now. I was able to follow Trevor Jones from AstroBackyard and combined his method with my own to obtain decent results.

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.
