Denkmeier BINOTRON-27 Quick Reference Instructions

BINOTRON-27 Quick Reference Instructions
Please carefully read and follow these instructions. It is a very good idea to become familiar with how the innovative
BINOTRON-27 eyepiece holders work. This will prevent confusion when operating in the field.

Using the Eyepiece Holders Properly

1. In figure 1. The Diopter Ring has been turned Counter-Clockwise (CCW) so that the third gradient line is
showing. If both eyepiece holders are set in this manner always, each eyepiece may be moved up or down to
fine-adjust focus for each of your eyes at the telescope.
2. Now grasp the diopter ring to prevent it from rotating, and turn the Eyepiece Locking Ring above it CCW.
This will release the hold on the Dust Plug and the Dust Plug can now be removed as shown in figure 2.
3. Now load your eyepiece into the holder. If the eyepiece barrel is not entering the eyepiece holder easily, turn
the Eyepiece Lock Ring a bit more CCW until the eyepiece barrel enters smoothly (only 1.25" format eyepieces
can be used in The BINOTRON-27)
4. Now while holding the Diopter Ring securely once again, turn the Eyepiece Lock Ring Clockwise to tighten
the Eyepiece Lock Ring. It does NOT need to be over tightened. Just moderate finger pressure is adequate. You
are now ready to observe in your telescope. The eyepiece is being held in a self-centered method 360 degrees.
Follow the BINOTRON-27 Manual for your particular telescope type (Ex: SCT, Refractor, Newtonian). The
main telescope focuser is always used first to achieve focus and then the Diopter Rings on the binoviewer
eyepiece holders can be used for super fine-tuning the focus for each individual eyepiece if necessary.

Collimating The BINOTRON-27

Each BINOTRON-27 has been accurately collimated to a high degree before shipping. However, we encourage
you to learn how to collimate. It's quite easy and you cannot damage the binoviewer if our instructions are
followed. After a little practice, you will find that the BINOTRON-27 Eyepiece Holders can be finely aligned at
the telescope in one minute or less! When we mention "collimating the Binoviewer", we are referring to aligning
the eyepiece holders. The prisms are carefully installed by us and set to an ideal position in our lab so that the
final alignment is accomplished with the eyepiece holders. This results in a perfectly collimated binoviewer.
Quick Instructions: Refer to the Main Manual for Additional Details
If you feel that the Binoviewer is producing uncomfortable or double images, please refer to Figs. 5 and 6 first.
It is best to view a stationary target in daytime to objectively determine if the eyepiece holders need re-
alignment. Observing a planet in your telescope is also a good measure, and the eyepiece holders can be adjusted
in in that application until the two-eyed image becomes a single perfectly merged
image that is very comfortable to view.
1. Fold the binoviewer body first so that the eyepieces match the width of your eyes.
You will see the image comfortably without a dark space in the center of the field.
This interpupillary (IP) adjustment must be done with all binoculars and binoviewers.
It is best to fold the bino inward past the best point and then outward again to be sure
you have arrived at the best IP Width.
2. If you wish to adjust The BINOTRON-27 collimation, loosen the lowest
Fig 4
large silver Collitron Ring (fig 4) by rotating it counter-clockwise until the entire upper series of black sections
(Grasp The Diopter Ring to Shift) can be shifted in a flat circular motion. Both the right and left Collitron
Rings should be loosened in this way. Do not over-loosen the large silver Collitron Ring. the idea is that the
upper black section of the eyepiece holder which includes the Diopter and the Eyepiece Lock Rings can be
shifted in a flat plane but should not tilt or rock excessively. Shift by grasping the wide black Diopter Ring.
