12 inch binoscope project

#1

Post by AdriGlassPusher »

Greetings,
This is a project I have been working on recently, a binocular telescope with twin 12 inch mirrors. I got an idea to build myself a big binocular telescope after visiting few very pristine dark sky locations and realizing that i Prefer binocular viewing. I love wide fields of view and colorful images of stars large exit pupils provide, hence binoviewer is something I didnt consider. Perhaps if I build a long focus newtonian for planetary use I will consider binoviewers.

I dont have an access to either a tig welder or an oxyacetylene burner so all connections are screw based. But the frame is pretty stiff and at least the base will be heavier due to all these screws thus helping the balancing thing. I also left the trusses oversized because I have a tendency to miss the focus point, which happened on couple of my previous builds.

Anyway, here is the current state of the project.

Great project!

I was wondering, why not put two 12" Meade truss Dobsonians in a frame with a diagonal for each 2" eyepiece? I presume the focus might not be far enough out without shortening the trusses, and the secondaries are too small after doing that. But, if that could be done, would it not save a lot of work?

Good luck with your project and keep us posted please!

This is what I had in mind, a binoscope made of 2 Dobs on an EQ platform. This link has all the details, HTH,
