Observing 8./9.9.2016 in Leistilänjärvi

Date: 08./09.09.2016
Time: 23:00-02:00
Observing site: Leistilänjärvi, Nakkila, Finland
Instrument: N250/1200 mm (10” Newton)

NELM: 6.6
SQM: 20.43
Darkness of the background sky: 3
Seeing: 2
Transparency: –
Weather: Clear sky, mist, +1C

Observed objects: NGC 7448

This time I went observing to Leistilänjärvi, Nakkila with Jarkko Suominen, one of the active members of Porin Karhunvartijat. This time it was very misty, and transparency was rather poor because of this. Nevertheless, I made my routine variable star observations, and besides this, I observed also NGC 7448, a galaxy in Pegasus with my 10” Newton.

NGC 7448

This was the only deep sky object I observed during this session. NGC 7448 is a galaxy located in the constellation of Pegasus, just 1 degree north from alpha Pegasi. Of this object I wrote following notes:

@120x: A rather faint and small galaxy, appeared as an oval shaped nebulous glow, long axis in N-S orientation, no details visible.

So this time no more deep sky observations because of poor observing conditions.

Observing 5./6.9.2016 in Leistilänjärvi

Date: 05./06.09.2016
Time: 23:45-00:30
Observing site: Leistilänjärvi, Nakkila, Finland
Instrument: N250/1200 mm (10” Newton)

NELM: 6.2
SQM: 20.59 – 20.43
Darkness of the background sky: 3
Seeing: 2
Transparency: –
Weather: Some high clouds, mist, calm, +5C – +2C, Aurora in the northern sky

Observed objects: NGC 6802, 6830

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.

Observing 1./2.9.2016 in Leistilänjärvi

Date: 01./02.09.2016
Time: 00:00-02:00
Observing site: Leistilänjärvi, Nakkila, Finland
Instrument: N250/1200 mm (10” Newton)

NELM: 6.6
SQM: 20.8 – 20.76
Darkness of the background sky: 2
Seeing: 2
Transparency: –
Weather: Clear sky, calm, Aurora arc in northern horizon, +10C – +9C

Objects observed: NGC 1342, 1444 and 7086

During the first night of September, I went again to my Leistilänjärvi -site to do some routine variable star- and deep sky observing. This time it was relatively warm, and conditions were rather good! There was though an Aurora arc in the northern horizon, but it didn’t interfere my observing attempts too much.

NGC 1342

During the night, my first object was NGC 1342, an open cluster located in constellation of Perseus, about 6 degrees SE from beta Persei. Of this object, I wrote following notes:

@50x: a rather easy and obvious open cluster. The cluster is well detached and relatively well concentrated. The cluster has rather large brightness range, and it appears to be moderately rich.

NGC 1444

The next object on my list was NGC 1444, a small and compact open cluster also in Perseus. This cluster is located in the northern part of the constellation, about 4 degrees NE from alpha Persei. Of this object, I wrote as follows:

@ 120x: a rather faint-starred, poor open luster, which is dominated by a pair of stars in the cluster. In the cluster, the stars of this pair have considerably large brightness difference.

NGC 7086

The third and this time the last object of this observing session was NGC 7086, an open cluster in the constellation of Cygnus. This cluster is located in the northern part of the constellation, 10 degrees NE from Deneb and roughly 8 degreed west from beta Lacertae. Of this object I wrote following notes:

@120x: a rather small and faint open cluster, it appears to e rich, it is well detached and compact and it appears to have rather small brightness range. The visual diameter of the cluster is about 6 arc minutes.

Weather: Partly cloudy sky, calm

Objects observed: NGC 1513

During night between 11./12.8.2016, we went out with my fellow astronomy friends to have a perseid party in Leistilänjärvi, Nakkila. During the night we were able to observe several perseid meteors, and besides this, also some distant lightnings!

NGC 1513

Besides observing perseid meteors, I also observed some variable stars and I also made one deep sky observing. The object of my choice was NGC 1513, an open cluster in Perseus, located halfway between mu and lambda Persei. Of this object I wrote following notes:

@120x: a rather small, poor cluster, the cluster is pretty well detached from it’s background, not very well concentrated. Most of the stars of the cluster appear to be in a ring-shape.

Observing in Leistilänjärvi 15.-16.2.2016

Date: 15./16.2.2016
Time: 20:30-22:30
Observing site: Leistilänjärvi, Nakkila, Finland
Instrument: N250/1200mm (10” Newton)

NELM: 5.3
SQM: 19.30 – 19.00

Weather: Clear sky, calm, snow on the ground, first quarter Moon in the sky, -10 C

Objects observed: NGC 1535, NGC 2539

In the night between 15th and 16th of February 2016 me and three other active members of Porin Karhunvartijat (Jarkko, Tomi and Santeri) drove to Leistilänjärvi, Nakkila to do some observing.

Leistilänjärvi is located in municipality of Nakkila in central Satakunta region, just 20 km SW from Pori. The place is a very large field, that has originally been a lake, but it has been dried out and transformed into agricultural land. The horizon is really open to all directions, there aren’t virtually any obstacles in any direction, se there is a true zero -horizon in that place. The downside of the place is that it is located in the immediate vicinity of the urban conglomerate of Pori-Ulvila-Nakkila-Harjavalta, which means that the place is very light polluted. In the middle of the fields, there aren’t any street lights of course, but the sky is not dark at all. The Bortle class of the place is perhaps 5 (subruban sky).

During the night when we were out observing there, the conditions were far from being optimal, and that was partly caused by the everpresent lightpollutedness of the sky, and also by 1/4 Moon that was shining at high altitude in the southern sky. Also there was snow on the ground, which was degrading the conditions even more. During the night, I also was having problems with the collimation of the mirrors of my telescope, and that’s why I couldn’t use high magnifications at all.

During the night Jarkko and Tomi were observing planet Jupiter, that had already risen above the horizon, and Santeri as a newcomer was learning by watching the pursues of the others.

During the night, I had some deep sky -objects on my list, even though the conditions weren’t optimal. During the night I observed two objects: NGC 1535 and NGC 2539.

NGC 1535

NGC 1535 is a planetary nebula in the constellation of Eridanus, which is best visible in midwinter. It is located at pretty low altitude in Finland, but nevertheless I tried to observe it. Here are my notes from NGC 1535:

@75x: Large and bright planetary, the shape of the nebula appears to be a round and symmetrical disc. The center of the nebula seems to be a little bit brighter than the outer parts.

NGC 2539

After I had finished observing this winter-planetary, I went on to observe an open cluster NGC 2539 in constellation of Puppis. The object is located in the northernmost part of Puppis, and it is located 8 degrees south from Alpha monocerotis. Of this object, I wrote following notes:

@80x: Faint-starred, a little bit scattered cluster without any significant concentration. Because of low altitude and poor conditions, only the brightest stars of the cluster were visible. The cluster is located next to 4,7 mag star 19 Puppis.
