This incredibly rich
stellar scene was imaged in western Aquilla, and is roughly centered
on Sharpless 2-72. Just above is a rich Milkyway star cloud,
and to its right is a very obscure but bright PK 36-01.1 planetary
nebula also known as Sharpless 2-71. A dense obscured globular
cluster NGC6749 appears to its lower left, and a surprise extremely
faint planetary nebula - StDr101 discovered only recently is
a teal colored sphere in the upper left corner.
