The ever-popular Rosette Nebula (NGC 2237–9/46) lies 10° east of Betelgeuse and is an impressive telescopic sight. Deep imaging reveals the line of dark Bok globules — small dense clouds where baby stars are forming — that appear to lie suspended within the nebula. The imager took 12⅓ hours of exposure with a 3.6-inch scope in SHO filters.
