• Target: NGC 6819
• Const: Cygnus
• RaDec: 19h41m +40.11
• Type: Open Cluster
• Scope: AT102ED
• Setting: 110x
• Class: I 1 r

If you were to draw a line between δ Cygni and β Cygni, NGC 6819 would be about 33% of the way between the two starting from δ Cygni.

Had I not known that this was an Open Cluster, I would have guessed it to be a Globular Cluster. A very beautiful but small cluster whose appeal is also found in the way its framed next to brighter stars in the area.

A gentle background glow was present hinting at many dimmer stars that I could not resolve.

• Target: Harvard 20
• Const: Sagitta
• RaDec: 19h53m +18.21
• Type: Open Cluster
• Scope: AT102ED
• Setting: 110x, AV
• Class: II 2 m

Harvard 20 took a little bit to find. It is situated pretty close to M 71. I had to reconfirm it’s location one or two times because I had trouble seeing it at first.

Eventually AV helped dimmer stars pop into view and allowed me to confirm the location.
