Item no. 82003
SRP: £169.00
Warranty: 24 Months

The  Zoom Eyepiece is a great addition to your Celestron Regal M2 Spotting Scope or upgrade to the standard TrailSeeker zoom eyepiece. The wide field of view at lower magnifications helps you bring subjects into the field of view quickly and  follow them as they move.  When you want to see more detail or bring subjects in close simply increase the magnification.

Fully multi-coated optics increase light transmission through the optical path and deliver crisp, high contrast images with outstanding resolution.


Excellent eye relief of 20 mm allows for comfortable viewing for both eyeglass and non-eyeglass wearers.  Eyeglass wearers can see the entire field of view while looking through the eyepiece with their glasses on due to the extended eye relief.

For those that do not wear eyeglasses, the twist up eyecup correctly positions the user’s eye behind the eyepiece at the correct distance for optimal viewing.


Not only does the Zoom Eyepiece provide stunning views in the field, but you can also attach an SLR camera to this eyepiece with an optional T-Adapter and a T-ring. Capture those impressive views and share them with friends and family when you return home.
