Photos involving a larger region or the entire Moon.

Unless stated otherwise, all photographs will be oriented such that north is up and lunar west to the left.
|Moon Occults Venus on 2009-04-22|
The weather just wasn't going to cooperate for this event, but I did get a few photos while the clouds were rolling in. Note that at 12×, Venus appears as a crescent.
|Lunar Eclipse at Sunset on 2007-03-04|
00:26 - 01:00 UTC
camera on tripod with 3× telephoto
f/4.9 - ISO 100
first photo @ 1/4 s; all others @ 1/8 s.
A 15 mph wind and freezing temperatures made taking these photos
an uncomfortable experience, but worth it. The eclipse was beautiful
and taking the photos was a good learning experience. Two other
people braved the weather with me although everyone spent most of
the time in their cars.
To those of us on the Earth, the apparent motion of celestial objects is dominated by the daily rotation of the Earth. Superimposed on this are the motions of the Earth, Moon and other planets as they move in their orbits. During a lunar eclipse, the Moon, Earth and Sun are aligned such that the Moon moves through the Earth's shadow cast from the Sun. With this lunar eclipse, here in the Midwest, the Moon rose just as it was leaving the darkest part of the Earth's shadow, the umbra. So we're easily able to see the Moon's eastward motion as it orbits the Earth by using our shadow as a reference point.
You may also note that the Earth's shadow on the Moon appears curved. This is, of course, because the Earth is round. This (repeated) observation from many lunar eclipses was one of the earliest proofs that the Earth was round. Furthermore, Aristarchus of Samos, in his book On the Sizes and Distances, probably written around 240 BCE, used comparisons of the diameter of the Moon to that of the Earth's shadow to help estimate the size of the Moon, and the relative distances to the Sun and Moon.
|On Friday, August 4, at 10 PM CDT (2006-08-05 3:00 UT), Rick, in Bowie, MD, and I, in Roeland Park, KS, simultaneously took photographs of the Moon expressly for the purpose of measuring the lunar parallax. From these photographs, I measured the parallax to be 861 arcseconds. This implies a geocentric distance of 356,296 km; a value -6.8% in error from the true distance. I also measured the lunar diameter to be 1,910 arcseconds implying a diamteter of 3,273 km; -5.8% in error. A summary of my computations is available and Rick's results can be found on his web site.|
|20.8 Hour Old Moon|
2006-05-28 2:14 UTC (9:14 PM CDT May 27, 2006)
32.0 mm eyepiece with 1.0× telephoto (39.1×)
This is a single 1/15 s - f/4.9 - ISO 400 photo. I enhanced the contrast slightly.
|Officially, the new Moon was at 5:26 UTC on 2006-05-27. This was the last shot before losing the Moon in the trees. It's elevation was about 4° at this time. The variations in brightness along the crescent appear in photos taken a few minutes earlier and so are probably real.|
|Moon Occults Antares|
9:50 - 12:03 UTC March 3, 2005
|The time series was taken at 1/15 sec - f2.8 - ISO 400. The contrast was reduced to minimize the Moon's glare. All photos were taken afocally using a 32 mm eyepiece with the reducer corrector giving an effective magnification of 24.6×. All images are the same size and centered upon Antares thus showing the true relative motion of the Moon. My buddy Rick put the images together into a short movie.|
