DescriptionSpiral galaxy NGC 6946 (noao-n6946).jpg |
English: This is a two-minute exposure taken on the night of September 26th 1994 (UT of observation 27/09/94:06:30) with the 1k detector. This photograph shows a region 200 arc seconds square. The brightness of the image has been converted to color (a technique called pseudo-color) using a simple orange/red-shading-to-white transformation, purely to make a more attractive picture. Sky conditions during this phase of the commissioning were not ideal, and this image has a "seeing" measurement (average FWHM of several stars) of over 1.1 arc seconds. About this object NGC 6946 (Arp 29) is a face-on SAB(rs)cd galaxy in the constellation Cygnus. This classification refers to the presence of a small core with multiple well-defined arms (cd), with a poorly-developed bar across the middle (AB) and an inner confused ring (rs). Nearly twenty million light-years from Earth, it is over seventy thousand light-years across and more than fills this picture. At least one supernova has been observed in this galaxy.
