This is the Crab Nebula (Messier 1) I tried this 15 years or more ago on the same telescope and well...it was crap. In researching this Nebula, processing and artistic preferences vary, VERY widely.
I only have 100 minutes of subs on this using a dual band filter with basic processing. I shot this in crappy skies as a test for tuning my Edge 11HD and off axis guider setup. I rather liked it, so I am keeping it and not reshooting.... well maybe this year.

The Crab Nebula is an expanding remnant of a star's supernova explosion. It is one of the brightest supernova remnants in the sky and is located in the Perseus Arm of the Milky Way Galaxy.

In 1054, Chinese astronomers took notice of a “guest star” that was, for nearly a month, visible in the daytime sky. The “guest star” they observed was actually a supernova explosion, which gave rise to the Crab Nebula, a six-light-year-wide remnant of the violent event. _NASA
