Collimating your refractor telescope is quick and easy when you use this 1.25" Cheshire collimating eyepiece. You see in seconds the collimating situation of the telescope, you also can use the Cheshire on newtonian telescopes.

The TSRCKOLLI collimator was developed for Ritchey-Chrétien telescopes, but also for all other types of telescopes, like refractor, Newtonian or SC Cassegrains - made in Europe

• The corrector allows the collimation of almost all optical systems with high accuracy.
• Suitable for all 2" receptacle with precice 2" barrel to avoid tilting
• LEDs are powered by 2 normal 1.5V AA batteries (batteries are not included)
• We recommend the collimator mainly for RC telescopes, Cassegrains and Schmidt Cassegrains as long as they have a center mark on their secondary mirror. So a top collimation state of the telescope can be reached even at daylight.
