About this image
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.
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.
