Diagram of Parts
The BINOTRON-27 Super System has been designed to focus at three magnifications in irtually any telescope
designed for typical single eyepiece use. Not only is focus achie ed, but three powers are accessible using the
patented Power x Switch while using only one pair of eyepieces.
Becoming familiar with the arious parts of the B-27 Super System will be ery useful and allow smooth and
trouble free operation. Obtaining focus in arious telescope designs is dependent on using the B-27 Super
System correctly. In the following pages, there are descriptions and pictures detailing proper usage for
Newtonians, Refractors and SCTs. Importantly, become ery familiar with the diagram of the B-27 CollitronTM
Eyepiece holders on the following page. Otherwise, incorrect parts of the eyepiece holder assembly will be
turned at night during use in the field and this will become frustrating. By spending time indoors in the light of
your home and using the eyepiece holders correctly, misidentifying the eyepiece holder parts at night can be
a oided.
Referring to the abo e diagram, all parts are required when using a Newtonian Telescope. See the Newtonian
Telescopes Section for specific instructions. When using a Refractor and other scopes that work similarly such
as classical cassegrains, Mewlons, Planewa e Telescopes, some Maksuto s, and many Ritchey Chretians, the
parts labled D and E are not used. refer to the Refractor Telescopes section. In SCTs, the parts labeled D, E and
F are not used so refer to the SCT section. Specific use is explained with more detail in each of the sections on
Newtonians, Refractors and SCTs. So, please learn how to properly use the B-27 Super System by reading the
sections on any telescope that you will be using. It is ery simple, as long as the brief instructions are properly
followed.

Eyepiece Holder Parts and Use
The patent pending CollitronTM equipped eyepiece holders are a Denkmeier inno ation that we are ery excited
about. The Bino iewer can be collimated in a minute or less and ery easily using this feature. This is thoroughly
explained in the page following this one. See the ideos at denkmeier.com on “Choosing A System” page.
Howe er, the Collitron Ring is not the only feature that is special about the B-27 eyepiece holder. The diopter
rings on each eyepiece holder allow the user to obtain a ery sharp focus for indi idual eyes. Therefore, those
without perfect 20/20 ision can adjust focus for both the right and left eye while iewing through their B-27
Bino iewer System. In fact, these new focusing mechanism do not rotate the eyepiece. The eyepiece mo es up
and down in a ery smooth motion. The focus adjustment has been set to an ideal speed as well. A change is
easily obser ed, but the motion is still considered to be "micro".
Loading the Eyepieces
The top "Eyepiece Locking Ring" (EPLR) allows the eyepiece to be inserted smoothly by turning this uppermost
ring counter-clockwise and remo ing the Dust Plugs. This allows an internal self centering split ring to expand.
Once the eyepiece barrel is fully inserted, the Locking Ring is then turned clockwise until the eyepiece is held
securely. O er tightening is not necessary but the ring should be turned to a point where it is nicely finger-
tightened.
Focusing Individual Eyepieces
Now, the diopters should be turned upward but only
slightly by rotating the Diopter Ring
Clockwise. If both Diopters are mo ed upward so
that perhaps the second white gradient line below the
+ sign is showing, each diopter may now be used at
the telescope and be mo ed both up and down for
sharp indi idual focus in each eye. Each person's
eyes may focus differently so the indi idual using the
B-27 will want to take note of where the diopters are
set for best focus so that this can be quickly readied
for each obser ing session.
Note: It is our opinion that focus should be monitored
and adjusted as needed during a nights' obser ing.
Rather than assuming one is in perfect focus, we ha e
found that it is essential to check focus of each
eyepiece periodically as sky conditions change and
the scope is mo ed to different locations of the sky
throughout the night. Viewing in proper and sharpest
focus is too important to ignore or lea e to chance. It
is our recommendation that you use the focusing feature of the B-27 as often as you feel necessary! E en when
iewing with single eyepieces, one should be checking focus frequently. The same holds true for iewing with
the B-27 Super System.
Do Not Over-Tighten The Diopter Ring
It is recommended that the eyepiece barrel be fully inserted into the eyepiece holder initially with the diopter
fully bottomed out (turned clockwise). Howe er, it is not necessary nor ad isable to bottom out the diopter too
tightly. Over-tightening the diopter mechanism when turning counter-clockwise after it bottoms out can
then make it hard to free when turning clock-wise, and the lower Collitron Ring may then also become
loosened unintentionally and eyepiece holder collimation will have to be performed again. This is only
somewhat incon enient though and can be quickly taken care of by using the Collitron Rings to collimate the
BINOTRON-27. You will find that this is a fast and simple process, and e en enjoyable to many. (see pages 4-6)

Collimating The BINOTRON-27TM
Collimation is Easy! Below is a Brief Explanation Followed by a Very Simple Procedure.
Many Telescope users become ner ous when faced with the prospect of collimating an optical instrument.
Howe er, this is required if optimum performance and aberration-free images are to be obtained. Generally
speaking, telescope components such as mirrors and lenses must not be tilted or shifted from an ideal
relationship to one another or aberrations in the focused and defocused image will be seen. In the case of a
bino iewer, when we are referring to "collimation", we are actually dealing with alignment of the left and right
eyepieces so that they form a single image when merged. An object seen in the left eyepiece field at a certain
location should be seen at the same location in the right eyepiece. So we are not dealing with tilting optics or
aberrations, because a poorly aligned bino iewer will generally not introduce aberrations, only a "double
image". This poorly merged double ision results when the target object such as a planet or star is located in
different areas in each eyepiece field. A ideo on the “Choosing A System” webpage demonstrates this.
In order to mo e the object to the same exact area in each eyepiece field, we mo e the eyepiece holders, not the
object! The Collitron Eyepiece Holders ha e been designed to shift in a 360 degree direction on a flat plane.
Note that we at Denkmeier "set" the prisms first, and the fixtures hold these prisms in place permanently. The
Final Collimation using the Collitron Holders can be fined-tuned so that e en the highest power images are in
the same location in each eyepiece field. Once this is done, the bino iewer will gi e extremely relaxed, two-eye
iews at all magnifications. Collimation will become so quick and easy, that it may be repeated as often as you
feel the need. We e en feel that the Collitron System makes this process enjoyable.
Preforming Collimation
Load your eyepieces into the holders first before loosening The Collitron Rings. See preceding page.
The diagram at the right illustrates how the Collitron Ring is loosened. It should be rotated counter-clockwise to
a point where the black parts abo e the Collitron Ring can be grasped and the entire holder may be shifted in any
directions. Do not o er-loosen the Collitron Ring. The goal is to loosen it only enough so that both the right and
left holders can be mo ed in any direction in a flat plane. If
the Collitron Ring is loosened to much, the eyepiece holder
can tilt. The Collitron Ring must only be loosened enough
so that the eyepiece holder can slide in all directions in a
flat plane. You are now ready to collimate. (See Videos)
ithout a Telescope
Firstly, we will offer a ery simple and excellent
collimation method. Our B-27 Optical Collimation Device
is a ailable as an option so that your Binotron-27 may be
collimated at anytime, indoors, without a telescope. This
de ice threads into the bottom of the Bino iewer or Power
x Switch and a beautiful in-focus target can be seen in both
eyepiece fields. It contains a fully coated optical lens, and a
laser engra ed target. A separate instruction sheet is
pro ided.
Simple and Fast Procedure
1.Load eyepieces into the bino iewer eyepiece holders by following the instructions on page 4.
2. Thread the B-27 Optical Collimation De ice into the bottom of the Bino iewer Power x Switch
3. View the target by looking through the eyepieces and facing a light source.
4. Make sure the target is in sharp focus for each eye. Consult B-27 Collimator instruction sheet.
5. Loosen each Collitron Ring a bit so that the Upper sections of the eyepiece holder can be shifted. A small
6
amount of friction should be present when shifting the holder. Note: The range of motion of the holder is quite
limited but a small amount of mo ement goes a long way in relocating an image seen in the eyepiece field.
Recap: Loosen the Collitron Rings just enough so that the eyepiece holders slide ( but do not tilt) a small
amount in any direction.
6. View the B-27 Collimation target while sliding one or both holders in a flat plane. You will notice
that the B-27 Collimation target becomes double, and ery uncomfortable to obser e with two eyes, and then
merges and becomes one single image that is comfortable to obser e as the holders are shifted.
7. When the image becomes ery comfortable to iew, tighten one Collitron Ring down firmly.
8. Now, while looking through the bino iewer with both eyes, close one eye and iew the target carefully with
the other eye. While iewing the target, obser e an area of the image carefully and now open the closed eye so
that you are using both eyes. Did you notice a double image of that target area that quickly came together as a
single image after a ery short delay? If so, slightly shift the holder with the still-loosened Collitron ring in ery
small increments. Test again by repeating the one-eye blink method. You will quickly obtain an ideal holder
position and there will be no delay in achie ing a perfectly merged single image with both eyes. This process
should take minutes or less once you become accustomed to the process. Once you ha e found this position,
tighten down the remaining loose Collitron Ring. Check things again using the same blink method. After a few
times, this process will become easy, rewarding and fun! You will ha e mastered BINOTRON-27 Collimation.
Collimation Using a Telescope
The same method outlined abo e can be used in a telescope. Rather than using the optional B-27 Optical
Collimation de ice, just focus on a planet or star field in your telescope. Carry out the same procedures as
described abo e, only the object iewed in your telescope will be your target. While collimating on astronomical
objects using your telescope at night works well, it may be easier if your telescope can focus on con enient
terrestrial targets in the daytime since they do not mo e and you are working with the holders in bright daylight.
In fact, we will outline a ery objecti e method to test collimation in daylight using a telescope below. It should
be done in daytime using a fixed target. Of course, ery large telescopes may not be able to find terrestrial
targets to focus on. In those cases, collimate while iewing astronomical objects, or purchasing the optional B-27
Optical Collimation De ice .
Daytime Collimation Using a Telescope (Refractor or SCT)
Setting Vertical Target Location Setting Horizontal Target Location
The main goal when collimating is to achie e a ery comfortable strain-free iew while using both eyesin your
bino iewer. If a ery objecti e, but somewhat more time consuming method collimation is preferred, we outline
the following procedure . Once the Horizontal and Vertical positions of a target become identical in both the
right and left eyepieces, collimation may be considered to be of a ery high order and can be objecti ely
measured. Please refer to the diagram abo e. The Procedure is outlined on the next page.

Note: Some degree of offset in the Horizontal position is acceptable and can e en increase the 3-D perception
that many obsr ers report when iewing planets and star clusters! Whether such offset in the horizontal aspect
becomes uncomfortable may depend on the indi idual and the amount of offset employed. Feel free to
experiment! On the other hand, ertical positions of a target in the right and left eyepiece field must be ery
close if not exact, or eye strain will occur.
Procedure
1. Focus on a nearby target and place that object close to the ertical edge of the eyepiece field. It should not
touch the edge of the eyepiece field but be ery close to the edge. Set the target in either the right or left eyepiece
only. It is best to start iewing with the eyepiece where the target appears closest to the upper ertical 12 o'clock
position. The other eyepiece will show the target in a lower position further down from the fields upper edge.
2. Now examine the target in one eyepiece only where the target is ery close to the field edge in the ertical
position. If necessary, mo e the telescope to place the target there, as close to the field edge but not touching.
3. Look in the other eyepiece. Is the object in the same position or further down from the field edge?
4. Adjust the eyepiece holders after loosening the Collitron Rings until the object is in an identical
ertical positions in each eyepiece field in relation to the upper field edge. This can take a few minutes.
5. Check the horizontal position as well. Alternating between ertical and horizontal positions while adjusting
the holder will e entually result in achie ing a ery high order of alignment. Yes, it takes some time and getting
used to, but it is a ery objecti e measure of the degree of collimation when both ertical and horizontal
positions of a target are identical in both the right and left eyepiece fields!

Collitron Ring Tightening Tool
We pro ide a tool that allows the user to tighten the
Collitron Ring if they feel that finger pressure is not
adequate. This is generally unnecessary but since the
amount of "finger strength" will ary from person
to person, we felt that including a tool was probably a
good idea. The Collitron Ring features three holes
so that at least one can easily be accessed no matter
where the Collitron Ring ends up in rotation after it is
finger tightened. Please do not o er tighten the
Collitron Ring! The ring should only be tightened to
the point where it will not become loosened while
operating the upper black rings used for locking and
unlocking the eyepiece and adjusting indi idual focus
(see page 3).
The Power x SwitchTM
The Dual Arm Power x Switch is our patented de ice in ented by Russell Lederman of Denkmeier Optical.
It functions in arious ways, depending on the telescope type being used. The three magnification factors
produced are different depending on the
telescope. This is explained in more detail in the
sections labeled Newtonian, Refractor and SCT
use. The name "Power x Switch" is actually
erbalized without the "x". We needed to add
the "x" for trademark purposes. A fully coated
optical doublet is housed in each carrier arm
(two arms). So there is a low power mode, a
mid power, and a high power mode. The low
power lens is always housed in the lens carrier
installed on the Logo-Side of the Power x
Switch Body. The non-Logo side contains the
highest power lens. The Mid-Power is achie ed
with both Power x Switch arms in the out
position. Only one arm can be mo ed inward
into the light path at a time, and should be mo ed in
completely, until tra el terminates.
The illustration at lower right shows the low
power arm on the Logo-Side fully inserted into
the light path of the bino iewer. The
magnifications that result are indicated in the
photo. These magnification factors are
multiples of what a single eyepiece would
produce. Ex: If an eyepiece renders 100X when
used as a single eyepiece, it will produce 130X
when used in the B-27 Super System with the
Low Power Arm mo ed to "IN" , when a
Newtonian or Refractor is used. It will produce
only 66X when used in an SCT. This is
explained in more detail later in this manual.

Using Newtonian Telescopes
Please refer to the Parts Diagram on page 2.
The B-27 Super System is shipped in the case fully assembled and ready for use in Newtonian Telescopes. What
you will recei e is shown abo e. Note that the illustration also shows the B-27 with optional D21 Eyepieces. The
D21 Eyepieces are not included unless you ha e ordered them. The Super System Assembly consisting of Power
x Switch, 2" Part O Nosepiece, Middle Newtonian Spacer with Sil er Lock Ring, and finally the Multi-Purpose
OCS Cell must be inserted fully into your focuser until the Power X Switch is flush with your focuser drawtube.
1.Now, the Lower Power Arm is pushed in. Rack your focuser drawtube in until focus is achie ed.
2. If focus is not achie ed, remo e the entire assembly from the telescope and thread out the Middle Newtonian
Spacer and Sil er Lock Ring from the 2" Part O Nosepiece. The Sil er Lock Ring may be a bit tight. Unthread it
counter-clockwise to allow the Middle Newtonian Spacer
to be lengthened outward (unthreaded). Try to focus again
by sliding the entire system back into the focuser until
flush. Remember that the Low Power Mode requires the
most in-tra el of your focuser. The Middle Newtonian
Spacer must be lengthened until you can rack inward just
past focus. It is important to be able to go inward past the
focus point, and then outward to a perfect focus in order to
be sure that perfect focus has been achie ed. E ery scope
is a bit different which is why the Middle Spacer's ability
to be lengthened is so important. Once the Middle
Newtonian Spacer has been set properly, the Sil er Lock
Ring can be threaded back downward until flush with the
2" Part O Nosepiece. If focus is not achie ed in Low
Power Mode, please see "Troubleshooting".
10
Newtonian Use (continued)
Once Low power Focus has been achie ed, the next is mid power. Mo e the Low Power Arm completely out.
Now both Power x Switch arms are in the
out position. This is mid power in
Newtonian Telescopes. You must rack your
focuser draw tube outward until focus is
achie ed. This is considered by many to be
the ideal power mode for obser ing planets.
Only the front OCS Lens is being used now
to bring focus through the B-27 Body to
your eyepieces. While all of the Power x
Switch optics are of ery high quality, many
belie e that the fewer optics there are in the
light path, the better the image quality.
The next power mode is the highest. This is
achie ed when the arm on the non-logo side
of the Power x Switch is mo ed into the light
path. This requires the most out tra el. If you
rack your focuser drawtube completely out
and still do not achie e focus (which is
possible with many low profile focusers),
loosen your drawtube thumbscrew and pull
the bino iewer assembly out a bit until you
achie e focus and then go outward a slight
amount past that point. The 2" tubes of the
Super System Assembly pro ide an
abundance of contact area allowing this to be
done without any issues. Hopefully, you can
still rack inward and achie e low power focus when pushing in the logo side arm. It is possible that with some
telescopes, all three focus positions will not be reached without the need to withdraw the Super System
Assembly outward in highest power mode. This depends on how the Newtonian mirrors, and focuser ha e been
spaced.
Trouble Shooting
Images seem poor:
In the unlikely e ent that this occurs, check collimation of the telescope. with the B-27 Super System in place.
Diffraction patterns should be unchanged when using the B-27 Super System as compared to a single eyepiece.
Howe er, the scope should ha e the collimation fine tuned using a stellar diffraction pattern in certain cases, for
optimal performance. This may be caused by focuser drop due to the weight of the B-27 Super System. In fact,
many obser ers choose to re-check collimation when the scope is pointed at arious areas of the sky! It is always
a good idea to be able to examine a diffraction pattern and fine tune the Primary Mirror collimation so that the
airy disc of the diffraction pattern appears at dead center as focus is closed down to a point.
Do I need a counterweight?
Yes, ery likely. Any hea y accessory should be counter weighed. There are so many methods that one can
employ and there is a wealth of information on the internet to help you decide which one is best for you.
I can't reach focus in Low Power Mode no matter how far I lengthen the Middle Newtonian Spacer.
Call us. We can pro ide a spacer cell that threads between the Newtonian spacer and the OCS Cell and this will
sol e the problem and allow the Newtonian Spacer to be also be closed back down a bit. Another alternati e is to
mo e your primary mirror collimation bolts higher, pushing the mirror a bit closer to the secondary mirror. A
third alternati e requires your truss poles to be trimmed slightly. In solid tubes, the mirror cell can be mo ed up.
