Limitations of
ordinary binoculars
You’re probably aware that
the color correction and reso-
lution of all high powered
binoculars are far less than
ideal. Usually the size,
weight, cost, inconvenience
and lack of interchangeable
eyepieces render them un-
desirable for all but the most
die hard fans.
Enter Bino Vue
We immediately recognized
the advantages of a binocu-
lar attachment that is used like
an ordinary binocular as far
as setting interpupillary dis-
tance without refo-
cusing and is set up
as easily as chang-
ing an eyepiece.
Because of the
high cost and a few
otherlimitations,we
hesitated bringing
this product to mar-
ket. However, we felt the as-
tonishing experience, in par-
ticular for planetary, lunar,
doublestar,and globular clus-
ter viewing should not be
denied.
Why add an image
amplifier
Our 2.0x image amplifier/
corrector compensates for
Bino Vue’s 5.1" of optical
path length as well as the
slight amount of naturally oc-
curringcolor and astigmatism
introduced into the image by
the additional prism glass.
Mostnoticeableinfast scopes
and at high power, we felt it
important to design out this
degradation. Bino Vue is the
only fully corrected system
available today that will nei-
thervignette at thewidest field
nor compromise your
telescope's high power per-
formance.
Bino Vue Uses
BinoVuecomesstandardwith
the Flat Coupler and 2x Am-
plifier installed on the body.
This permits the Bino Vue to
be used in all telescopes with
just a moderate focuser in-
travelrequired. The 2x Ampli-
fier has filter threads to accept
1¼" filters. The Flat Coupler
provides enough space for
the inclusion of filter without
hitting the diagonal mirror
when using 2" Tele Vue di-
agonals and the 2"-1¼" Tele
Vue "High-Hat" adapter.
If your telescope re-
quires the Bino Vue to be
parfocal because it cannot
reach focus in the standard
configuration then;
1) unscrew the 2x Amplifier
from the Flat Coupler,

Concept: At Tele Vue, the driving force has always been to get as close as possible
to the contrast, resolution and field of the most remarkable instrument of all: the
human eye. While always respecting the need for viewing comfort, convenience and
value, we have broken through conventional barriers to bring you eyepieces and
telescopes with performance dramatically closer to the “spacewalk viewing” goal.
One major limitation has been the lack of binocular viewing. Look at the night sky
with one eye closed. It’s missing a lot. Open both eyes and see the dramatic
improvement in resolution, contrast, faint star detection and viewing comfort. All
this plus an illusion of depth. Yes, your brain loves two eyed viewing, even when
it is not true stereo. Open your eyes and mind to Bino Vue — Al Nagler

2) unscrew the Flat Coupler
from the Bino Vue body
3) Thread in the Extension
Coupler to the Bino Vue
body
4) Thread the 2x Amplifier
into the Extension Coupler
It is still safe to insert the Bino
Vue into 2" Tele Vue diago-
nals with the 2"-1¼" Tele Vue
"High-Hat"adapterwithouthit-
ting the diagonal mirror. If
a filter is threaded onto the
Bino Vue in this configura-
tion, it WILL
hit the mirror.
Take precau-
tions to ensure
this does not
happen.
If you will
also be using
the Bino Vue
with tele-
scopes that
have enough
focus in-travel
to allow the
Bino Vue to
come to focus
without the 2x
Amplifier,
such as SCTs,
then;
1) install the
Extension
Coupler as
described
above
2) thread the
empty Exten-
sion Tube into
the Extension
Coupler
Then, refocus
theSCTmirror.
(This does increase the E.F.L.
of the SCT about 25% due to
the nature of the secondary
relativeto the primary). Note:
some ghosting may be seen
when bright objects are out-
side, but near to the viewing
field. Careful eye positioning
can minimize this.
Using Bino Vue
Bino Vue is very simple to use.
First, start with two Tele Vue
eyepieces to ensure exact
matching of eyepiece focal
lengths. Insert the eyepieces
into the EYEPIECE HOLDERS
and tighten both Eyepiece
Clamp Rings just enough to
hold the eyepieces securely
against gravity, but loose
enough to slide them up and
down with your hand. Doing
so will make diopter adjust-
ment a snap.
Next, set the interocular
distance. While looking into
Bino Vue, grasp both sides of
the body and either squeeze
together or spread apart until
the two circles merge into one
(just like binoculars). Focus
the scope normally. If there is
a difference in focus between
the eyepieces, simply slide
one of the eyepieces in or out
to match the focus difference
of your eyes.
A note on the collet type
EyepieceHolder. Thismethod
of holding the eyepieces in
place insures the optical axis
of the eyepieces remain in-
line with the optical axis of the
rest of the system. Slight
misalignment of the optical
axis can cause fatigue or eye
strain when viewing for long
periods and at high powers.
A Final Note
If you use Bino Vue with any
of our telescopes for terrestrial
viewing, you will enter a new
world of visual experience.
And, whether you’re viewing
in daylight or at night, you will
hardly realize that each eye is
seeing less than 50% trans-
mission normally seen at the
same magnification. The rea-
son is that the resolution and
contrast are so high, and two
eye viewing seems to “re-
cover” some of the light loss.
Indeed until you go to very
high powers, you may prefer
these views with seemingly
darker sky backgrounds.
Warranty
Each Bino Vue is carefully
collimated and tested at Tele
Vue. Bino Vue is warranted
for 5 years against manufac-
turing defects. Dropping or
banging it may disturb the
collimation.Neverremovethe
covers or any other part, or
you may void the warranty.
Disturbance of collimation is
usually evidence of abuse, it
is warranted at the discretion
of Tele Vue. Please handle
Bino Vue carefully as you
would a telescope.
