Binoviewer to a Telescope

There are many options to connect the binoviewer to your telescope. Depending on the 
back-focus and the optical design of your telescope, you can chose the option which 
best fits to your needs.

Assembly with T-2 Coupling Nut

With glasspath correctors 1,25x 

# 2456314,   

1,7x 

# 2456316

 or 2,6x 

# 2456317

When delivered, a T-2 counter nut is pre-mounted to 
the MaxBright

 II Binoviewer. 

Tip: By changing the Glasspath Corrector, you can 
achieve different magnifications with one pair of 
eyepieces.

Option 1: Assembly with a T-2 Star Diagonal

Especially with a prism diagonal, this is the most 
common option, because a prism allows for a very 
short light path. By using the T-2-thread of our star diagonals, you can remove its 
eyepiece clamp and save several centimetres of back-focus. The lightpath of a prism 
is shorter than that of a mirror.
When using the T-2-thread, you simply screw one of the GCs 

# 2456314,  # 2456316  or 

# 2456317

 into the star diagonal (without the centering plastic ring which is included 

with the glasspath corrector). Our star diagonals provide a matching thread for this. 
You can find an overview of the different models and their optical lengths on page 5.
To use a T-2 star diagonal at a telescope without T-2-thread (but with a standard eye-
piece clamp), you need in addition either the 1¼" nosepiece 

# 2458105

 or the 2" nose-

piece 

# 2408150

.

1.  Remove the dust covers of your star diagonal.
2.  Screw the glasspath corrector into the body of 

the star diagonal as shown in the picture to the 
right.

3.  If necessary, attach a 1¼" nosepiece 

# 2458105

or a 2" nosepiece 

# 2408150

 to the other side of 

the star diagonal.

4.  Remove the dust caps from the binoviewer and 

attach the star diagonal to its T-2-thread. Turn 
the counter nut until both parts are connected 
securely. Untighten the counter nut slightly to 
change the orientation of the binoviewer, if nec-
essary.

Inserting the glasspath correctors 1,25x, 
1,7x and 2,6x into the Baader T-2 star 
diagonals.
