Very clear skies allowed me this look at the famous supernova remnant M1, also known as the Crab Nebula, in the constellation Taurus.
I studied the object for about 3 and a half hours over two nights before I made the sketch--apparently being a planetary observer has turned me into a real grind.
I used Strathmore 400 series medium 80 lb. paper and a 2B pencil. I adjusted the gamma a little during the scanning process and flipped the sketch digitally to achieve the correct image view.
M1 has a fabulous history and some astonishing facts about its structure. If you're interested you can read more about it in my observing report in the DSO forum.
