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.

The adapter extends a male T2 thread to M48x0.75 (2") filter thread without increasing the length.

• Female thread: T2 - M42x0.75
• Male thread: 2" filter thread - M48x0.75
• Length: only 2.5 mm - the mechanical length is optically not effective, as the adapter is completely sunken in the connection adapter
