Observing in Friitala 10./11.8.2016

Date: 10./11.08.2016
Time: 00:15-02:00
Observing site: Friitala, Ulvila, Finland
Instrument: N250/1200 (10” Newton)

NELM: 5.7
SQM: 20.14
Darkness of the background sky: 4
Seeing: 2
Transparency: –
Weather: Clear sky, windy, some high clouds, +12 C

Objects observed: NGC 7062, (variable stars)

The opening of deep sky observing season 2016-2017! The sky was still light, and there were some high clouds, but still I decided to start the deep sky season. Besides observing deep sky, I also observed variable stars in the early evening.

NGC 7062

During the night, I made only one deep sky observation, the object of my choice was NGC 7062, an open cluster in northern part of Cygnus, about 7° ENE from Deneb. Of this object, I wrote following notes:

@120x: A rather small, compact, pretty faint open cluster. The brightness range of the cluster appears to be considerably large, the cluster is well detached from it’s background.

Objects observed: NGC 2266, 2304, 2395 and 2355

In the early days of March 2016, I had two observing sessions during two nights in a row. During the latter of these sessions (2.-3.3.2016) I was observing in my Friitala observing site. During the night conditions were OK winter conditions, altough there was som cloud interference in the later part of the session. Eventually the clouds forced me to stop observing. Nevertheless, I was able to observe four objects: NGC 2266, 2304, 2395 and 2355. All of these objects are open clusters in the constellation of Gemini.

NGC 2266

My first object of this evening was NGC 2266, a small open cluster located 2 degrees north from epsilon Geminorum. My notes of this object are as follows:

@160x: A small, compact and faint-starred cluster. The cluster is well concentrated and detached. The cluster is mostly visible as a starglow, only some of the brightest stars of the cluster are visible straight.

NGC 2304

The second object of this session was NGC 2304, which is a faint and small open cluster in the constellation of Gemini, located 3 degrees SW from Zeta Geminorum. Of this object, I wrote following notes:

@80x: Very faint, small and compact open cluster. Some of the brightest stars were visible at times at the threshhold of visibility, but mostly the cluster is visible just as a round, unresolved, hazy patch of dim light.

NGC 2395

My third object of this observing session was NGC 2395, just another faint, small and pretty unknown open cluster in Gemini. It is located 3,5 degrees SE from Lambda Geminorum. Of this object, I wrote  following notes:

@80x: A small, faint and rather scattered and poor cluster, not very well concentrated.

NGC 2355

The last object of this observing session was NGC 2355, faint and small open cluster in Gemini. It is located 3 degrees south from Lambda Geminorum and 2,5 degrees west from NGC 2395. Of this object I wrote as follows:

@80x: A small, faint and compact cluster. The cluster is mostly visible as a glow. Only handful of the brigthest stars were resolved.

Objects observed: NGC 2126, NGC 1857

In late February, between the 28th and 29th of February i had a short observing session in Friitala. During the session, I observed two open clusters in the constellation of Auriga: NGC 2126 and 1857. During the session, conditions were OK winter conditions, and Moon wasn’t interfering this time. For this session, I had been able to collimate my telescope well enough, and bad collimation wasn’t problem anymore. This time though tube currents were causing some problem, because I didn’t have enough time to let the telescope cool down.

NGC 2126

My first object was NGC 2126, a small open cluster in Auriga, 5 degrees north of Beta Aurigae.Of this object, I wrote following notes:

A small, faint-starred, rather poor cluster, no obvious concentration.

NGC 1857

My second object of this session was another small and faint open cluster in Auriga: NGC 1857. This object is located 3 degrees SE from eta Aurigae, in the middle of the “box” -asterism of Auriga. Of this object, I wrote following notes:

A small, rather faint and poor but still obvious cluster. Misplaced on Skymap Pro 9.
