Comet McNaught has really developed nicely. Jenn and I viewed it for the
second straight morning at Kaibab Lodge, near the North Rim of the Grand
Canyon. I used an unconventional equatorial mount to take a 3-minute exposure
through a 200mm lens. The mount is the tracking platform for a 10-inch scope
that also nicely supports a photo tripod. The other details are f/4 and ISO
1000 on a Canon 50D. SQM readings for the site before the Milky Way rose were
21.85 to 21.90.

What initially appeared to be some sort of defect just to the right of the coma
turns out to be NGC 891, a beautiful edge-on galaxy. The bright star in the
field is Almach (Gamma Andromedae).
