Celestron Telescopes Collimation Specialty Eyepiece 1-1/4"

About this item

Line it up! See all your telescope is capable of delivering with the Celestron collimation tool. The optical performance of most Newtonian telescopes can be optimized by collimating, or realigning, the telescope's optics, as needed. This procedure is easily accomplished with Celestron's collimation tool, a handy accessory that comes with detailed instructions. It makes short work out of what was once a laborious chore.

The Celestron Cheshire Collimation Eyepiece is ideal for precise collimation of Newtonians and helpful for aligning Schmidt-Cassegrains. This special eyepiece fits into 1¼'' focusers or diagonals.

Alignment is easy using the small opening on one end and thin cross hairs at the other end. The collimation eyepiece is more accurate than the simple Collimation Tool.

  • Used for alignment of optics in reflector telescopes
  • Combination of sight tube and Cheshire tool
  • Properly aligned optics produce crisp sharp images
  • A less expensive alternative to laser collimators

Excelent value, but not laser

Customer review by Driveway Astronimer

5.0 stars by Driveway Astronimer

The collimator eyepeice helped me percisely align my Meade DS2114 newtonian telescope. I found that my telescope had a defect in the alginment of the eyepeice holder with the secondary mirror. This defect would not have been revealed with a laser collimator. From the images of the device I thought before purchased it might be a laser collimator but instead it uses a bullseye image from ambient light with a peehole and crosshair to do a similiar job. It is well made with accurate optical alignment. The one page instruction sheet needs to be read carefully but it is not overly complicated. Even if you have a laser collimator this device is a useful addition to your astronomy tool kit.
