Orion nebula

One of several sketches I have made of the Orion nebula. At the time of the observation the transparency was sub-standard (at my site about 5.8) and dropping from ZLM 5.5 when I set out, too 5.3 two hours later when I finished. I still managed to catch a lot of details in the nebula.

Inspired by a remarkable drawing made by Leopold Trouvelot in 1874 and discussed in Joseph Ashbrook’s The Astronomical Scrapbook (p. 386), I later decided to focus on the bright central region of the nebula. At this time transparency reached ZLM 5.7.
