You mean your C8.5 maybe. I am sure you are loosing at least 3/4 inch of apeture with this configuration and your obstruction is now likely 40% or more. The focal lenght is likley to be about 2750mm.

I am sure that you like this setup, but you are loosing a lot of true field and image brightness.

Only matters if it matters to you though.

Sweet looking setup.

Did you have to move the mirror forward some, or are you using some kind of OCS to reach focus?

I am badly wanting to build a Newtonian and would like it to binoview with no OCS or GPC and am curious to know you you got there.

I have thought about basing mine on a Go-To Dob, but have become concerned about the ergonomics when using binoviewers. I really like the ability to have infinite adjustment when using the Binoviewers on an SCT or refractor, but I am concerned that if I can't rotate the tube, I may have difficulty getting comfortable positions.

But I like your setup and am interesed in the details if you could share them.

One of these days to test this, I am going to replace the cloth shroud with a sheet of 0.060" ABS wrapped around to make a tube, it would be captured by the truss poles.






I had to loosen up on the collimation bolt a little and have the bino's in a 2x shorty barlow.

I am going to add another set of holes for native viewing, but how much additional in travel is needed?

with this craddle the tube adjusts for balance and rotation very easily. its a stellafane design. and moves so smoothly and when you stop, it stops. very little vibration when focusing. and with the denver chair, I don't know why it took me so long to build something so simple.

How do you like your Nikons? How large is the clear aperture? Any issues to speak of? I'm currently looking into converting mircoscope binocular heads..

so I just had my newt outside with the binoviewers and no corrector. I was finding the focus by slipping the tube down over the primary until I came to focus while pointing at zenith. I left the focuser tube about mid travel. I had to move the mirror in 4". I'll have to change the current 1.5" secondary to a 2.14" I have laying around.

I want to make it convertible so I'll have to use two different stalks with the different size secondaries attached and a second set of holes in the back of the tube for two different mirror locations.

I'll save that project for next weekend when the wife is away.

Good thing the tube's craddle adjusts for balance and rotation very easily.

I've heard great things about the optical performance but the eyepiece holders are not adjustable.

Here's a similar setup Denis, but using the Powermate T-ring adapter. And on the left is the 1.7X Newtonian Coma Correcting Glasspath.

Yep, but I do not like T-ring adapter, I am affraid that my Mark V body will fall if I do not screw it well at dark
This adapter I have, is universal and simple like using bino as 2" eyepiece.

I know what you mean Denis, it's another reason I am really liking the new Denkmeier Binotron 27s - nice solid secure nosepiece attachment.
