Simply Print the Attached PDF at 100% Scale, Cut Out the Crosshair or Blank for Your Eyepiece Size, and Don't Forget to Cut Out the Hole in the Middle! Then Glue It to the Inside Diagonal of the Eyepiece and Enjoy a Handy Reflection While Collimating. Using the Cheshire Collimator is a Breeze. For a Detailed Guide on How to Use This, Check Out Gary Seronik's Excellent Introduction to Telescope Collimation. I Created This Cheshire Collimator Because I Needed One for My Ancient 0.965" Tasco TR11 and Figured Why Not Make It Available in Other Sizes Too!
