Just stepping into this field. For the users to get the grasp of the size and scale of the objects populating our night (and day) skies, I take attention to keep the same scale (a field of view of about 41.2x27.5 arcminutes) and start by introducing the most familiar objects.
Messier M39 (or NGC7092) is an open cluster in the constellation of Cygnus situated in the vicinity of the star Deneb (Alpha Cygni). It is only 800 light-years away from us and consists in about 30 stars inside a sphere of about 7 light-years diameter. The field of view is slightly larger than the previous images to capture all the stars in the cluster.
