Hi,Anyone familiar with using the Geoscope?What I would like to know is if the standard Geoscope can view two 4x5 stereo images placed side by side (a Left image and a Right image).How about two 5x7's?Basically I want to know how large of photograph format can these specific viewers can view.I am not interested in other competing products, just this one, thanks for any help!http://www.ascscient...om/stereos.htmlhttp://www.stereoaid...t/geoscope.htmlhttp://www.forestry-...age.asp?mi=5872

We use those for aerial mapping on 5x7's and they worked well. You can get them from Amazon.com for half that price too.
