About this image
This is a two-minute exposure taken
on the night of September 1st 1994 (UT of observation 02/09/94:07:06)
with the 1k detector.
This photograph shows a region 200 arc seconds
square which has been compressed in brightness (approximately a double
logarithm) to show both bright and faint features. Observing conditions
during this phase of the commissioning were not ideal, but this image
has a "seeing" measurement (average
FWHM of several stars) of about 0.9 arc seconds.
Orientation: N up, W to the left.
Galaxy NGC 7741 is a barred spiral galaxy of type SB(s)cd, meaning that
it has a central bar-like concentration, evident here, and a small
number of fairly open large-scale spiral arms. The galaxy reaches about
50% further out than this picture covers, so the outermost regions are
not visible. NGC 7741 is quite nearby, and is receding from us at only
1.7 million miles per hour.
Size: about 35 thousand light-years across.
