?esky: Wolf 359 je oranžová hv?zda nad st?edem této astrofotografie
Deutsch: Aufnahme von Wolf 359 mit einer Astrokamera an einem 10" SCT mit 1.040 mm Brennweite.

Der Rote Zwerg ist etwas oberhalb der Bildmitte gut zu erkennen. Es ist zu beachten, daß sich die Position von Wolf 359 jährlich um knapp 5 Bogensekunden in Richtung "4 Uhr" verschiebt, so daß die in dieser Aufnahme vom 21.3.2009 gezeigte Lage des Zwergsterns zwischen den Hintergrundsternen bereits 2010 nicht mehr genau gestimmt hat.

Das Bildfeld erstreckt sich über 16 × 12 Bogenminuten, ein Pixel entspricht ca. 1,5 Bogensekunden.

"Natürliche" Orientierung: Norden ist oben, Osten links.
English: This picture of Wolf 359 was taken with an astrocamera of 1.040 mm focal distance. The red dwarf is well discernible a little bit above the center of the image. It shifts toward "four o'clock" each year by bare five arcseconds. This means that the star's position in this picture from 21st of March, 2009, has already not any more been accurate in 2010. - The picture spans over 16 × 12 arc minutes. One pixel is equivalent to approximately 1.5 arcseconds. North is upward, east to the right.
