18mm X-Cel LX 1.25" Eyepiece

This 18mm eyepiece is designed for astronomers who want a 60-degree apparent field of view for planetary and deep-sky observation. It fits any telescope that accepts 1.25-inch accessories and suits observers who value parfocal convenience when swapping eyepieces. The six-element, fully multi-coated optics deliver crisp, high-contrast images of the Moon, planets and brighter deep-sky objects.

Twist-up eye guard and parfocal design

Installation is as simple as sliding the 1.25-inch barrel into the focuser and tightening the thumbscrew; no tools are required. The twist-up eye guard adjusts quickly for comfortable viewing with or without glasses. Parfocal performance means minimal refocusing when changing between X-Cel LX eyepieces, so a quick swap keeps the target sharp. The only common issue is forgetting to remove the protective caps before the first use.

60-degree field and 18mm focal length

The 18mm focal length provides mid-range magnification that works well for lunar detail, planetary discs and larger star clusters. The 60-degree apparent field gives an immersive view without the edge distortion found in narrower designs. Light transmission remains high thanks to the fully multi-coated six-element set. Observers needing very low power for vast nebulae or very high power for tiny planetary features will need different focal lengths.

Questions about this item

How do I confirm the eyepiece is working as intended after setup?

Point the telescope at a bright planet or star cluster; a crisp 60-degree field with sharp edge-to-edge stars and minimal refocus when swapping eyepieces shows the 18mm X-Cel LX is performing correctly.

What is in the box and what must be bought separately?

The box contains the 18mm X-Cel LX 1.25" eyepiece with its twist-up eye guard and protective caps; a 1.25" focuser or diagonal is required on the telescope but is not included.

Which version or capacity of this eyepiece should I choose?

Model 93425 is the single 18mm focal-length variant in the X-Cel LX line; choose it when you want a 60-degree apparent field at 18mm in a 1.25" barrel.
