31.10.2011 at 23.00 - Espoo (IV)
Lauri Kangas, Kirkkonummen komeetta

Having borrowed a color CCD camera, I’ve left the shooting of emission nebulae less and focused on nicely colored broadband targets like star clusters. My intention was to continue my long Messier 45 project, but as I waited for the Sifters to ascend, I exposed the binary star Misamis in Perseus for 1h15min. After changing the target, the sky clouded immediately. Thanks to the two-star set, the evening was not wasted and I got home at midnight. Sometimes clouds are useful.

Starscape image

3.3.2011 at 21.31 - 23.32 - Vihti (IV)
Kari Kalervo, Ursa (Etelä-Suomi)

The unusual if not as unique theme of the picture is the fall of the constellation. Here, the constellation of Orion counts in the hourly exposures on March 3 in Vihti. In the camera, I used a self-timer. There was a bit of suspicion of leaving the expensive camera alone for a couple of hours to describe, but no one is moving in the darkness of the night in a closed hangout.

Several bright halo forms

27.4.2011 at 10.42 - 11.30 - Tampere (III)
Jari Luomanen, Ursa (Länsi-Suomi)

My lunch break was enlivened by the impossibly bright 22-degree overhanging halo of power. It looked really beautiful in the clouds in the morning for at least three quarters. In the afternoon, in three countries, I separately noticed another horizon ring, a 120-degree side sun, and a weak Wegener counter-solar arc. A wonderful halo day in honor of halo april.
