This star field covers around 3 degrees south of alpha Scuti. It corresponds to just east of a vast Hα nebula of Sh2-54 in Serpens, contains some minor nebulae. In upper part of the image, a bluish reflection nebula of IC1287 has been distributed around a 6th magnitude star with a span of 18×12 arc minutes.
At about 50 arc minutes south of IC1287, you can detect an indistinct planetary nebula of Abell45. Although the nebula has an apparent diameter of 5 arc minutes and is emitting reddish light, actually the light is NII line from the ionized nitrogen atoms, not Hα line from the hydrogen atoms.
