Seeing was pretty good tonight in spite of the 2/5 prediction. It was good enough to stare at Jupiter and the subject features through my 9mm ortho (300x mag) for a fair bit, and I could see Oval BA plain as day. I picked up Io's shadow through the eyepiece just as it emerged from the terminator, and its crispness invited me to shoot it. It was another blustery night, but at least I knew what to expect while driving the mount. Here's a cross-eye stereo pair animation of it all as it passed through zenith:

Nice one! It's taken me a while to get it, but I was finally able to see the 3D effect you are going for, it looks fantastic. I'm only able to do it for a few seconds before my eyes start going crazy crazyeyes.gif , but the "vertical" displacement of the moon is quite visible.

Very cool! You also get a boost in image quality from the real-time stacker in the occipital lobe. But yes, 3D from 2D is tricky business…everyone's eyes are built a little differently, and they change over time. I now use reading glasses, but I get better results on cross-eye pairs without them (and I can stare for hours without the crazyeyes.gif ). But for wide-eye pairs, I can't focus at all without my glasses, and to see them it's more like gottahurt.gif .

 

What I really need is one of those stereo viewers. Apparently they're still in production…I just ordered a couple off ebay.

Actually, I found it easier by magnifying the screen to 200%, and sitting about 50cm away from the screen. Less cross eyed, a bit more natural (for me), anyway.

The stereo effect is really neat.  I reduce the screen size and stare into infinity.  Works just as well and is a bit easier on the eyes.

Thanks, Brett! I worry that by using the wide-eye method (accomplished by staring into ∞), you're getting the pseudoscopic effect instead of actual 3D. Here's a wide-eye image to try:

Here's a smooth, 24-bit color version (click for full-resolution):

Unfortunately, it's tough to separate Io and the shadow from the planet, so the "tween" frames (actually derotated adjacent frames) have some elongation of both. The tradeoff is animation smoothness.
