Observing site: Stormälö, Parainen, Finland
Instrument: N250/1200 (10” Newton)
Darkness of the background sky: 1
Weather: Clear sky, light breeze, dry air, no dew problems! +13 – +11 °C
Objects observed: NGC 6756, 7296, 7510, 7142, 1245
In late August I was able to go to observing in my Stormälö observing site, in Parainen, in the archipelago of Turku! The night was as close to perfect as it ever can be! It was warm and air was dry, which made observing very pleasent!
During the night I made 5 observations, first object of the night for me was NGC 6756, and open cluster in Aquila. The object is located near NGC 6755, another, slightly brighter open cluster in the constellation. These two objets are located 4,5 WNW from delta Aql. Of this object, I wrote following notes:
@120x: a small, faint open cluster, pretty well detached from it’s background, compact. Most of the stars visible as a starglow.
NGC 6756 observed with 10” Newton
NGC 7296 (= NGC 7295)
My next target was NGC 7296, an open cluster located in the constellation of Lacerta. The object is locatd just at the “head” of the lizard, only 45′ E from Beta Lac. Of this object, I wrote following notes:
@120x: a small, faint open cluster in rich star field. Compact, pretty well detached from the background, not very rich.
NGC 7296 observed with 10” Newton
The third object of my night was NGC 7510, an open cluster in the easternmost part of Cepheus, about 5 degrees NE from delta Cep, about halfway between Beta Cas and delta Cep. Of this object I wrote following notes:
@120x: a small, compact open cluster, well detached from the background, the cluster has pretty large brightness range. The cluster is triangular in shape, the long axis of the cluster is in SW-NE -direction.

After having observed NGC 7510, I aimed my scope to NGC 7142, yet another open cluster in Cepheus. This cluster is located about 5 degrees SE from beta Cep and 4 degrees NE from alpha Cep. Of this object, I wrote following notes:
@120x: a faint-starred open cluster, not very concentrated, not very ell detached from the background, small brightness range, at least the brightest stars of the cluster are in a shape of an arc that is opening towards south.
NGC 7142 observed with 10” Newton
The fift and last object for me for this night was NGC 1245, an open cluster located in the constellation of Perseus, just 3 degrees SW from alpha Per. Of this object, I wrote as follows:
@120x: A faint-starred, pretty rich open cluster, well detached from the background, pretty well concentrated and compact, the cluster has moderate brightness range. The stars of the cluster appear to be in shape of arc or bow.
