Denis, this is the first NV Bino I have ever seen that attaches to a scope. I have a Russian made monocular that is fun to use, but not the best generation. Is this thing very expensive?

I posted pictures of Baader Mark V bino, not Night Vision, it is above...I do not have experience with NV binos!

Mark V (Carl Zeiss) + Astro-Physics BARCON = Superb views, much better than standard Baaders GPCs

In what way is this Barlow much better than GPCs?
Don't believe that.....misleading and harmful

Simply, you can test GPCs vs BARCON, I do that, and sell all my GPCs! :)

Also, Baaders GPCs cause vignetting in some eyepieces!
Simply try BARCON vs GPCs!

I dont want nor need x2 magnification

I use a SIEBERTS zero mag OCS system in my 2" TV diagonal and the Baader T2 bayonet clamps my Mk V's right on top....with a pair of 14mm Delos for about x200 mag or 24mm Pans for around x110...Delos 10mm's for higher mag when seeing allows....

To make this work, you need to cobble together a few parts.

Actually there are TWO U.S. PVS night vision goggles that can be attached to a telescope. Both the PVS-7B/D (most common unit) and the PVS-7A/C (more rare these days and out of production) can be used provided that one replaces the standard 1X front objective with a c-mount adapter. After that, all one needs is a c-mount to 1.25 inch telescope adapter. The price for a Gen 3 tube new is around $2K. The PVS-7 housings can run from $300 used to around $900 new. The c-mount adapters cost between $50 to $75 new.

Also, Gen 3 image intensifiers are restricted to the U.S. by ITAR laws. However, Gen 2 intensifiers can be had in many countries. The PVS-7 housings accept the MX-10130 intensifier tube format which is available in both Gen 3 and Gen 2.

Hi Folks,

Denkmeier, BW Optik, and Televue. Why 3 pairs? I really don't know.

Clear Skies,

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. :grin:

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.
