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.

Steven R. ★★★★★

I've been fighting with my Newtonian's alignment for months, and this collimation eyepiece made the process almost foolproof—the crosshairs are crisp and the built-in Cheshire ring really helped center everything. Now stars are perfectly round across the entire field of view.

Owen C. ★★★★★

My telescope went from blurry to razor-sharp once I used this to line up the mirrors, and the crosshair pattern made it easy to see exactly where to adjust. It took me under ten minutes on a 1.25" focuser, and I'm honestly surprised how much crisper the planets look now.

Violet C. ★★★★★

The crosshairs and circle made it stupidly easy to line up my secondary mirror—no more guessing with a laser that drifts. My stars went from fuzzy blobs to sharp pinpoints on the first try, and the whole process took maybe ten minutes.
