This composite image of the February 20, 2008 Total Lunar Eclipse shows the Moon as it is entering the Earth’s shadow (right), in the middle of the eclipse, and as it is exiting the shadow. These three images were aligned using background objects so that the true size of the Earth’s shadow could be shown. You can get a feel for its size by drawing an imaginary circle matching the edge of the shadow on the first and last image. The Moon was placed to one side of the photographic frame so that Saturn (which was very close to the eclipsed Moon) could be included in the image.
07-VG7844 Comet 17P Holems, November 4, 2007 Photo taken with a stationary 400mm f/2.8 lens.
11VG0016 The Super Moon. This is a photo of the full Moon at Perigee, 221,565 miles (356,577 km) the closest the Moon gets to the Earth. This makes the Moon appear around 12% larger than it appear when it’s at Apogee 252,682 miles (406,655 km) the farthest distance from the Earth. The orange fringe at the bottom of the Moon is produced by atmospheric refraction. This is common for objects low on the horizon but it may be a bit surprising in this case because the moon was about 30 degrees above the horizon. 2200mm FL on full frame.
11VG1399 Sunspots on July 29, 2011
11DC2880 Sunspots July 29, 2011 The dark center of the spot is call the Umbra and the lighter gray area around the Umbra is call the Penumbra. The dark center of the larger spots in this photo are about two or three times the diameter of the Earth. An 1100mm f/7 APO lens with 2X TC (EFL = 2200mm) was used to capture these two images. A 5ND filter was use to reduce the light by 16 Stops in order to get the sun's light level in a safe range.
11VG0016-Moon at A & P: The moon travels in an elliptical orbit which means that sometimes the moon is closer to us than at other times. This image shows the dramatic difference in size that can result from that orbit. Both images of the moon were taken with the same optical setup and processed at the same sale.
11VG0016-Moon Stereo: In the previous image the moon is shown at a different scale due to the elliptical nature of its orbit. The moon also wobbles a little from side to side even though the moon keeps roughly the same side toward us here on earth. In this case I captured images of the moon close to the extremes of this wobble which can be used to create a stereo pair base on the different viewing angles. Adjust the size of this image (change window size) until the two moon images are about as far apart as your eyes are. Then view the left image with your left eye and the right image with your right eye. It may be a challenge to fuse the two images into one stereo image, but some people are able to train their eyes to view this image in stereo. (The image on the right was rescaled to match the size of the image on the left so you can see both images in stereo.)
