I think the images should be swapped side for viewing with crossed eyes. As they are I think the effect is much better when fused directly by relaxing the eyes as if looking into the distance, but focused on the screen - that way the moon really stands out better in 3D in front of the screen, rather than dished behind it. That is a slightly more difficult technique, but years of nova searching with eye loupes and pairs of film negs makes it easy for me
