This is M27, the Dumbbell Nebula, in Sagitta. Image consists of
12 5-minute sub exposures acquired with an ST-10XE using a
4.5nm Custom Scientific Hydrogen Alpha filter. The object was
low in the sky on a moonlit night of mediocre seeing. Scope was
an AP 130mm F/6 APO guided by an SBIG STV. The shooting location
was my light polluted yard 8 miles north of Oakland CA in SF Bay Area.
