Astrophyics sells one for about $950 ouch!. I havent seen it, but Roland told me that it, like the one Al Nagler was considering, did not defocus when you changed the interpupillary distance and that it was straight-through configuration. Has anyone tried one?

I have the Celestron/Baader-Planetarium stereo view. I heartily dis-recommend it. It looses focus when you change interpupillary distance. Far worse, mine lost its collimation after about 4 hours of use. It took me about 6 hours to re-collimate it. One must completely disassemble it to get at all the collimation scews.

However, when collimated, it provides wonderful lunar and planetary views with a AP traveller. I find it no help on deep sky objects.
