17. ed 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 binoviewer will generally not introduce aberrations only a double image This poorly merged double vision results when the target object such as a planet or star is located in different areas in each eyepiece field In order to move the object to the same exact area in each eyepiece field we move the eyepiece holders not the object The Collitron Eyepiece Holders have 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 even the highest power images are in the same location in each eyepiece field Once this is done the binoviewer will give extremely relaxed two eye views at all magnifications Collimation will become so quick and easy that it may be repeated as often as you feel the need We even 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 above the Collitron Ring c

29. ual Eyepieces Rotate Diopter Ring When Focusing Individual Eyes Now the diopters should be turned upward but only Only a Small Amount of Travel is Needed to change Focus slightly by rotating the Diopter Ring The Eyepiece Locking Release Ring is Located above Clockwise If both Diopters are moved 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 moved both up and down for sharp individual focus in each eye Each person s iets eyes may focus differently so the individual using the Eyepiece Locking Ring 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 observing session Note It is our opinion that focus should be monitored Diopter and adjusted as needed during a nights observing Ring Rather than assuming one is in perfect focus we have found that it is essential to check focus of each eyepiece periodically as sky conditions change and the scope is moved to different locations of the sky throughout the night Viewing in proper and sharpest focus is too important to ignore or leave to chance It is our recommendation that you use the focusing feature of the B 27 as often as you feel necessary Even when viewing with single eyepieces one should be checking focus frequently The same holds true for viewing with the B 27 Super System Dust Plug Installed Do Not Over Tighten The Diopter Ri
