This image has captured a star field of northeast region in Scutum.
The Milky Way around here looks bright, our naked eyes can detect easily like a lump of nebulosity, called "Star Cloud in Scutum",
or "Small Star Cloud" from a comparison with Milky Way around Sagittarius.
This image includes a bright open cluster of M11 in lower right hand side,
and small but many dark nebulae have been distributed around north part of M11.
You can easily recognize B110 or B113 etc. Both nebulae has small sizes about 10 arc minutes but you can appreciate complicated shapes.
