Description

NGC 6337 drawing inverted into positive.

The Scorpion's famous ring shaped planetary has a perfectly round shape. It's a shiny ring of smoke. The left side is a little brighter but the differences in brightness are minimal. The inside of the ring is not completely dark either. The inner stars are extremely faint and their position is so unreal - they are very hard.

Comparison with the photograph

The photo on the left, courtesy of Dr. Stefan Binnewies and Josef  Pöpsel was made using the 60 cm Ganymed Hypergraph of the Capella Observatory. The photo was made at the Amani Lodge in Namibia. The original photograph has been rotated and cropped to show a similar area as the positive drawing.

It is obvious that I didn't see the star chain in the center very precisely. I couldn't separate all of the three stars. Besides this and the beautiful green color, the eyepiece impression very closely resembles the photograph. It might be worth comparing the stars around the planetary nebula as well.
