LRGB exposure (20:10:10:15 minutes color binned 2x2) with STL-1301E camera
thru a 20" F/8.1 OGS RC Cass.
Here's a link (
http://www.kopernik.org/images/archive/m74.htm) to a page
with the same image plus images of M-74 and supernovae SN 2002ap and SN
2003gd. These images were taken with my ST-9E camera and both were
apparently on a night of better seeing (or I did something else better back
then).
