The Collitron Reticle allows The Binotron 27 to be collimated in a minute or less indoors with a pair of eyepieces. Only a well-lit room is required. No telescope is needed so you can check and super fine-tune your Binotron alignment if ever you feel it is necessary. A pair of eyepieces (we designed the Coliitron with our D21 Eyepieces though other brands work also) are all that is necessary!

To use, keep the power switch arms OUT, point to an evenly illuminated wall and you will view a reticle with grid lines in both the right and left eyepieces. 

Note that the threads are specifically for Binotron 27 Binoviewers. While this reticle may fit other brands of binoviewers with specially made adapters and it may function properly, we do not warrant or guarantee this product when used with other brands of binoviewers.
