NGC 6894

28.8.2022 at 01.09 - Orimattila, Artjärvi, Tähtikallio (I)
Toni Veikkolainen, Jani Katava, Kari Laihia, Keski-Uudenmaan Altair

We had photographed this object on Tähtikalli without colors about a year ago. Now we got the colors. There were serious problems with the humidity and the camera cooling had to be removed sometimes because of them, and otherwise the camera had to be operated at -15 degrees instead of the normal -20 degrees. In any case, the object of observation is recognizable.

NGC 7008

Toni Veikkolainen, Jani Katava, Kari Laihia, Keski-Uudenmaan Altair

The fetal nebula NGC 7008 was imaged in color. The fog on the ground hindered the view of the dim background stars in particular, but the main object itself stood out well due to the high surface brightness.

(397) Vienna (A894 YA,1894 BM,1941 WA1,1951 AV1) A mid-main belt asteroid imaged during the third evening of the 2022 August talcos. The asteroid was discovered by the French astronomer Auguste Honoré Charlois (1864-1910) on December 19, 1894 at the Nice Observatory (020 – Nice). The asteroid got its name from WIEN, the Austrian capital located on the banks of the Danube. The Romans established a military camp at Vindobona, on the banks of the Danube c. 50 BC, in the area of the current old town of Vienna, where the city is considered to have been born.
