The Greenbank Telescope

The Greenbank Telescope in Greenbank, West Virginia, is a radio astronomy telescope with a 100 meter dish antenna and is the largest steerable radio telescope in the world. An amazing site to see in person, this thing with a diameter greater than the length of a football field that pans and tilts around to point at various points in the sky. Digital cameras are not permitted anywhere near this or any of the other radio telescopes, as the electronics emits radio energy which interferes with the sensitive instruments. Fortunately, my 1950’s era Minolta Autochord is up to the task.

3D Observations

I recently purchased a Holga stereo pinhole 120 camera which I found on sale. Holgas, like Dianas, are “toy” cameras, basically reproductions of cheap plastic cameras made in Russia or China during the Cold War, and now marketed as niche items for “lomography“. This particular camera uses pinholes instead of lenses, so it requires a tripod to use properly.

Click on each photo to see a larger view. In order to see the 3D effect, you must cross your eyes as you look at these. You should see each photo move towards the middle until they overlap and there is only one image seen. It helps to focus on the most distant objects in the photo until your eyes sort of “lock on” to the photo. This method of printing them in cross-eye pairs was the simplest way for me to print them without the use of a 3D slide viewer or any other equipment of that sort.
