An interesting article and telescope thought JMI has been making this style of reverse binocular telescope for years: http://www.jimsmobile.com/buy_rb.htm
The 3D printed one does have some interesting aspects to it though.

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 :)

There are articulated prism eyepiece holders that would do this I believe, I just cannot remember what they are called at the moment.

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.

Thanks not_Fritz... Parts printing is going to be a thing in telescope making I believe. Many amateurs that are making their own interferometers are sourcing printed plastic parts from a common source. The key point is that prices are very reasonable.

A friend printed some setting circles, an adapter to mount the hour circle to the worm gear and a parfocal ring for a 2" eyepiece so far. I would have gone for finder rings but the setting circles are so accurate I don't even need the Telrad except for initial setup. It's like shooting fish in a barrel.
I'm here to do two things, build something and dump some light down it.

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.

These are the articulating rear prisms he used.

I looked through Jim's (from JMI) binoscope and was not able to get focus or collimation working. There was a complex control panel for this. I don't know how this version works but the idea of building it mechanically such that you can change the pupil distance mechanically such that collimation is not affected is good.

I still wonder why people don't buy binoviewers for a regular telescope instead, it avoids a major hassle. The aperture gain is sqrt(2) or about 1.4 so 2 x 8" would become about 11". I think you'd be much better of with a 12" mirror and binoviewers. With binoviewers the critical point is keeping the FOV the same with the bi-Tak probably too.

I know Matt(Rainmaker). In fact he built the wonderful 18" dob I have. 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 dual aperture true binoscope is quite different to the view through a binoviewer on a bigger aperture. 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 bright DSO'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.

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.

Yes, it's an illusion, but a very effective one. You can really lose yourself into the illusion. ;)
