Ostara are fast becoming a well known and respected brand when it comes to astronomical accessories, binoculars and telescopes.

Straight out the box, you will be aware how solid and well built this collimating eyepiece is.

Unlike laser collimators, the cheshire design can be used to align both primary and secondary mirrors.

Simply line up the cross hairs on the eyepiece with the centre circle on the primary mirror for correct collimation.

Accurate collimation is essential for high power observing. Stars will become more like pin points of light, and 

Planetary / Lunar detail will be enhanced
