These drawings of the shell structure are based on observations from a 222mm reflector f/6 (104x). The location was: Deurne, The Netherlands. Although the sky brightness during the observation period was varying, thanks to almost continuing northern winds, the conditions were in general quite well, for our country even extremely good.
