Image Field of view is 101 x 152 arcmin.
This image contains many objects in the field.
Upper left is NGC 7538 (Sh2-158) an emission nebula and is about 9,100 light-years from Earth. It is home to the biggest yet discovered protostar which is about 300 times the size of our Solar System.
Bottom left is M52 an Open Cluster at about 5000 light-years.
Left center NGC 7635 (Sh2-162) the Bubble Nebula is an emission Nebula at about 7000 light-years.
Upper right is Sh2-157 an emission nebula, sometimes referred to as (The Claw Nebula) at about 8000 light-years.
The small patch of green just to the left of the claw maybe an LBN168 nebula?
