It's a large but indistinct planetary nebula in northern Pegasus. The nebula has a catalogue number of PK104-29.1, but often called "Jones 1" in USA. A visual diameter is estimated larger than 1 arc minute, you can record a figure of the nebula only with small telephoto lenses in films. But the nebula is very pale, this image shows you only edges of north and south regions. The real shape of the nebula is almost round.
