One of my October project is capturing the Crab Nebula (M1).  It is one of the most interesting object that I want to photograph.  It is because that this supernova remnant was observed by Chinese Astronomers in 1054 when a very bright star (brighter than the sun) was observed that disappeared in a couple of days.  That supernova left a remnant which is now known as the Crab Nebula.

The image below is just my initial version as I’m still gathering data.  This is the result of almost no post processing aside from combining the narrow band channels to RGB.

2 years ago, I took a photo which looks like below.
