This time I went again observing to my Leistilänjärvi -observing site in Nakkila, Finland. This time there was lots of mist and air was humid, also there were some aurorae in the northern sky. Because of this, I did only two observations during this session.

NGC 6802

My first object of this session was NGC 6802, an open cluster in Vulpecula. It is located only 1 degree east from the famous Coat Hanger -asterism. Of this object I wrote following notes:

@120x: a small and faint open cluster, mostly visible as a glow, few individual stars barely visible. Well detached and compact.

NGC 6830

The second and last object for this short observing session was NGC 6830, yet another open cluster in Vulpecula. This object is located just 2 degrees west from the famous Dumbell -nebula, Messier 27. After doing this observation, I realized, that I had already observed this object in 2010, so this observation was actually an unintended duplicate observation of this object. Nevertheless, I wrote following notes of this observation:

@120x, a rather small but obvious cluster, it is pretty well detached from it’s background. The cluster has rather large brigthness range, about 10 to 15 stars are visible.
