Hello!

A new observing season has started here in high latitudes too. During this august, I have had time to do some observing, and here you can see some results:

Messier 11

Posted Image

Observation information:
Date: 19/20.8.2009
Time: 00.00
Location: Parainen, Finland
Instrument: N 250/1200 mm
Magnification: 80x
Field of view: 50,3'
Filter: -

Observation conditions:
Limiting magnitude: 6,6
Seeing: 3
Background sky: 2
Altitude: 21
Visuality: 2
Weather: Clear sky, moderate northern breeze

Description:
A very rich and bright open cluster. It is very compact and very well detached from the background. The cluster
is so compact, that it resembles a very loose globular cluster. There are one brighter star in the center of the cluster,
A very beatiful object, indeed!

Observation information:
Date: 20/21.8.2009

The body, neck and head of the swan are the brightest areas of the nebula. The nebula has also fainter areas, which became visible better with O III -filter.

NGC 7293

Some fantastic sketches there, from your location in Finland these objects must have been getting close to the horizon.

NGC 7293, marvellous. :goodjob:

Lovely sketches Juha! I thought we had it bad here in the UK, with too light summers, but you guys in Finland have it a lot worse. Hope you have a clear observing season!

Juha,

These sketches are great. :bow: :cool: :rainbow: Paul and Eric beat me to it. Great job on NGC 7293. After doing M 11 you must have needed a break with all those stars.

Beautiful sketches Juha! So happy to hear the summer has finally given way to less bright skies, I guess that is the price paid for living at such a high latitude! Every sketch is a delight to behold! :bow: :rainbow: :bow:

Juha,

Excellent observations of M11, M16, M17, and NGC 7293 (Helix Nebula). You have recorded these objects very nicely. Thank you for sharing them with us all.
