Rosette Nebula (NGC 2237-2239, 2246)
For the amateur observer, good sky transparency and a wide field of view will show a circular faint glow around 1° in diameter. Apertures in the 20-30cm range may reveal the central hole. Once identified, employ high power to scan along the nebulas edge where brightness variations and perhaps dark material may be seen.
