Celestron Cheshire Collimation Eyepiece – 1.25"

Precision Alignment for Peak Performance

Accurate collimation is essential to get the best optical performance from your reflector telescope. The Celestron Cheshire Collimation Eyepiece offers a reliable and precise way to align the optics of Newtonian reflectors, and it can also assist with the alignment of Schmidt-Cassegrain telescopes.

Designed for Newtonians, Helpful for SCTs

  • Specifically made for Newtonian telescopes, where perfect collimation ensures sharp, high-contrast images.

  • Can also be used to assist with the optical alignment of Schmidt-Cassegrain systems.

Easy, Accurate Collimation

  • Small viewing aperture at one end limits stray light and enhances accuracy.

  • Thin crosshairs and internal reflective surfaces provide a clear, structured view of the telescope’s optical axis for precise adjustment.

  • Ideal for aligning the primary and secondary mirrors with greater confidence than basic tools.

1.25” Compatibility

  • Fits any standard 1.25" focuser or diagonal, making it a universal tool for most visual telescope setups.

  • Durable, machined construction ensures reliable, repeatable results time after time.

Why Use a Cheshire Eyepiece?

Unlike simple collimation caps or laser tools, a Cheshire eyepiece uses ambient light and internal reflection to offer a real-time, parallax-free view of your optics’ alignment. It's a trusted method used by amateur astronomers and professionals alike.

Essential for Reflector Owners

Whether you're fine-tuning your setup for planetary detail or preparing for deep-sky imaging, the Celestron Cheshire Collimation Eyepiece helps you get the most out of your telescope—ensuring clearer, sharper, and more detailed views every night.

What happens if I don't like it?

We always want you to be happy with your purchase — so if you’re unsure, please ask us first. We’re always happy to give honest advice before you buy.

If the product arrives and you simply decide it isn’t for you, you can usually return it within the cooling-off period — as long as it’s unused, in perfect condition, and returned with all original packaging and accessories.

Because telescopes and optical equipment are large, delicate and expensive to ship, you’ll need to cover the cost of sending it back, and if we originally subsidised delivery, we may deduct our outbound shipping costs from your refund.

We’re a small specialist business, and unnecessary returns genuinely hurt us — so if you’re unsure at all, please talk to us first. We’d rather help you choose the right item than process a return.

How fast is shipping?

We aim to ship in-stock items as quickly as possible.

  • Most in-stock orders dispatch within 1–2 working days
  • Delivery usually takes 1–3 working days after dispatch (UK mainland)
  • Heavier / oversized items and special orders may take a little longer

You’ll receive tracking details as soon as your order is on its way.

Astronomy equipment often requires specialist packing and trusted couriers — we do this to keep your gear safe, not to slow things down. If you need something urgently, just ask and we’ll do our best.
