There are articulated prism eyepiece holders that would do this I believe, I just cannot remember what they are called at the moment.bobharmony wrote: ↑Mon Sep 02, 2019 6:01 pm Interesting article. Binoculars and I have never gotten along due to a life-long strabismus issue. My eyes point outward from each other, rather than aligning along the same axis. Great for wide peripheral vision, not too good for depth perception.
The article made me search for binoculars that are set up to deal with this condition. No luck yet, but I will keep plugging. Maybe someone will come up with a 3D printed version that lets the two optical trains point at different angles

I realise this is a very old post but I only just saw the reference to Matt's bino scope. Just posting this here for future reference.Lady Fraktor wrote: ↑Tue Sep 03, 2019 5:02 am I cannot remember what these prisms are called but I believe Matt (rainmaker) uses a set with his Tak bino refractor set up.
He would probably know if they would work for you.
I know Matt(Rainmaker). In fact he built the wonderful 18"I still wonder why people don't buy binoviewers for a regular telescope instead, it avoids a major hassle.
That's interesting because the 3D appearance is an illusion because of the large distance. I presume it's caused by the images not being quite identical while the ones from a binoviewer are? Just guessing.OzEclipse wrote: ↑Sun May 30, 2021 10:52 pm @SkyHiker wrote:I know Matt(Rainmaker).

I bought it from him so that he could fund the build the mark 1 binoTak and another more compact 18".
Matt's mk1 binoscope was if I recall, based on two TOA130's not TSA120's. I think he sold the two refractors individually, kept the back end and later built a dual 4" Tak which I have not yet looked through.
We keep saying we need to get him out here for a weekend but it never seems to happen. The view through that dualaperture true binoscope is quite different to the view through a binoviewer on a biggeraperture . We actually did that comparison one night. The view through the binoscope is much more 3D than a binoviewer splitting the image from a single optic. We compared a 12" Mewlon with binoviewer, with Matt's binoscope. The 12" obviously had a brighter image but everyone agreed the view through the dual Tak was more 3D and in a very good way. We looked at brightDSO 's and Jupiter. Jupiter actually looked like a 3D spheroid. The Tarantula was the same with the nebula taking on a distinctly and very satisfying 3D appearance.
Hard to put it into words but it was a truly remarkable view and a different experience to a binoviewer.

Yes, it's an illusion, but a very effective one. You can really lose yourself into the illusion.SkyHiker wrote: ↑Mon May 31, 2021 12:38 amThat's interesting because the 3D appearance is an illusion because of the large distance.
