With a fella at my astronomy club, we're interested in the making of a binoscope.
(pic related: it's 2 telescope side by side)
There seem to be awesome realizations on the internet, but close to no diagram or advice.
This is a 3 stage project:
1- we'd like to try it out with 2 newtonian telescope (skywatcher 200/1000) since we have the same model.
2- make a small frame that would use these mirrors (2x200) since we're not experienced in the telescope making business
3- scale it up to 2x300 or 350mm.
My biggest concern is finding good secondary mirrors, since they'll need to be bigger because lower on the light path.
Any diyer experienced in the field?';

Was just about to post a link to that forum.';
'What could a binocular telescope possibly do that a monocular telescope doesn't do better?
Celestial objects are far too far away for any sort of parallax depth perception ... aren't they?
Is it just to be able to view objects with both eyes? Wouldn't there be simpler ways to add a second viewing optic onto a telescope, rather than building two telescopes side-by-side?
So many questions.
It's interesting, I'm just curious what the purpose is.';

Thank you!

There's no parallax indeed, but your brain reprocess the 2 images to merge them into 1 with less fatigue. Having to close an eye to watch is a non-natural process.
I never tried it myself but it seems prety enjoyable to spend hours watching details.
Plus once you get into the big diameter telescope, the price growth exponentially with surface area. A binoscope has more technical challenges but isn't necessarly costly.
Binocular heads do exist but they works with prism, you loose a little bit of light in the process, and they're quite expensive.';
