The SH2-115 region near Deneb

A three-panel mosaic of the sky region near Deneb. At the center is SH2-115, the small round nebula to the upper left is SH2-116 (or PK 085+04.1), and to the right is SH2-112. All images were captured through a hydrogen filter during twilight from mid-June to mid-July. The streak in the upper right corner is an artifact, likely a glare from Deneb.
