There's a method that's the opposite of the cross-eyed style, and it works too. That's the type I can manage. -- Joe --- On Thu, 4/16/09, Patrick Wiggins <paw@wirelessbeehive.com> wrote: From: Patrick Wiggins <paw@wirelessbeehive.com> Subject: Re: [Utah-astronomy] More 3D To: "Utah Astronomy" <utah-astronomy@mailman.xmission.com> Date: Thursday, April 16, 2009, 11:22 PM Oh my Goddess, it actually works! I've tried this cross eyed stuff many times before and it's never worked. And, alas, I was not able to get it to work with the comet shots. But then I tried the Moon and it jumped right out at me. Same for the nebulae shots. Wild! I can't say that it was comfortable (my left eye feels like I pulled a muscle) but it was still a fun experiment. patrick On 16 Apr 2009, at 11:53, Jim Gibson wrote:
Chuck, This guy specializes in 3D images. Here is a cool one of the moon in 3D. http://3.bp.blogspot.com/_9HcYqbvUc4s/SdIcjcHpGCI/AAAAAAAACl4/JHElNuZ95_M/s1...
English is not his first language, but I have no complaints there as he is perfectly understandable. He says: Unlike many Deep sky objects, the Moon can be seen with enough parallax to form a real stereo pair. There is two ways to do it. First you take two pictures from other sides of earth at the same time and there will be some minor parallax. Secondly the libration of the Moon can be used for that, you just have to wait a longish time to have a same phase of the Moon but with differen libration amount.

The "wall-eyed" method? LOL! Most people who can't do the crossed-eyes method just can't seem to make one image overlap the other with crossed-eyes. Tilting the head is often needed to establish registration. Crossing the eyes too far is another common mistake. If you can focus on an object about six or seven inches in front of your face without too much difficulty, you should be able to use the crossed-eye method. Your eyes don't cross much more than they normally do when looking at something half a foot away. On Fri, Apr 17, 2009 at 12:10 AM, Joe Bauman <josephmbauman@yahoo.com>wrote:

Some people actually do the crossed-eyes method without realizing it. They call it "free fusing", but if an observer looks at their eyes, they are actually crossed!
