  • Page 2 Table of Contents 3. Diagram of Parts 4. Eyepiece Holder Diagram 5. Collitron Rings and Collimation Without a Telescope 6. Collimation Without a Telescope ctd, Collimation With a Telescope 7. Collimation With a Telescope/ Field Chart 8. Collitron Ring Tightening Tool, The Power x Switch 9.
  • Page 3 Diagram of Parts The BINOTRON-27 Super System has been designed to focus at three magnifications in virtually any telescope designed for typical single eyepiece use. Not only is focus achieved, but three powers are accessible using the patented Power x Switch while using only one pair of eyepieces.
  • Page 4 This is only somewhat inconvenient 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 even enjoyable to many. (see pages 4-6)
  • Page 5 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.
  • Page 6 Once you have 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 have mastered BINOTRON-27 Collimation. Collimation Using a Telescope The same method outlined above can be used in a telescope.
  • Page 7 Note: Some degree of offset in the Horizontal position is acceptable and can even increase the 3-D perception that many obsrvers report when viewing planets and star clusters! Whether such offset in the horizontal aspect becomes uncomfortable may depend on the individual and the amount of offset employed. Feel free to experiment! On the other hand, vertical positions of a target in the right and left eyepiece field must be very close if not exact, or eye strain will occur.
  • Page 8 (see page 3). The Power x Switch The Dual Arm Power x Switch is our patented device invented by Russell Lederman of Denkmeier Optical. It functions in various ways, depending on the telescope type being used. The three magnification factors produced are different depending on the telescope.
  • Page 9 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 receive is shown above. Note that the illustration also shows the B-27 with optional D21 Eyepieces. The D21 Eyepieces are not included unless you have ordered them.
  • Page 10 Newtonian Use (continued) Once Low power Focus has been achieved, the next is mid power. Move 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 achieved.
  • Page 11 In order to achieve a focused image, Refractors require optical assistance when using a binoviewer. Our Power x Switch and Optical Corrector System (OCS) allow focus to be obtained. The BINOTRON-27 Super System must be used correctly for focus to be achieved. We outline the methods below. There are a few refractors that were/are specially shortened in order to allow a binoviewer to focus.

  • Page 12: Trouble Shooting

    Some refractors have been made with removable extensions so that a binoviewer will focus without the need for optical lenses. If the BINOTRON-27 Super System is to be used with the Power xSwitch and OCS then follow the Refractor Instructions and make sure that the removable extension tubes are installed in your refractor so that it operates like a conventional scope.
  • Page 13 All SCT Owners should become very familiar with collimating the secondary mirror of their telescope. This is a must of the best optical images are to be obtained with both single eyepieces as well as the BINOTRON-27. It is recommended that one collimate the secondary mirror with the BINOTRON-27. A star can be centered and viewed with both eyes, and the secondary mirror can be collimated in the same way as when using a single eyepiece.

    Denkmeier Eyepieces Our Denkmeier Eyepieces are world renowned and for good reason - The glass used is high index, the coatings are the best, and the performance is exquisite. No, the D21s and D14s are not inexpensive. But remember that any pair of eyepieces used in the BINOTRON-27 Super System becomes three pairs! This is because they operate at three magnifications.
  • Page 15 Using filters in your telescope can greatly enhance the visibility of many deepsky objects. Being able to move filters in and out of the light path quickly is a great thing! That is precisely what our Denkmeier Filter Switch allows you to do. So, why not add our Filter Switch System to your BIONTRON-27 Super System.
