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.
Available for shipment to the USA and Canada only.
