3-Piece Set: 31.7mm Celestron Eyepieces (4mm, 10mm, 23mm) ①

These eyepieces are very popular and sell out quickly upon restock. Please note that this is a set of three. If you wish to purchase them individually, they are listed separately; please comment with the desired mm size on that listing.

They are well-known within the amateur astronomy community for their excellent performance relative to their price. With a 62° apparent field of view, they offer a very wide perspective, and the advertised moderate eye relief is indeed accurate, providing a comfortable viewing experience. These are recommended, cost-effective Celestron eyepieces (4mm, 10mm, 23mm, 31.7mm/1.25 inch).

This set includes the commonly supplied high-magnification 4mm, low-magnification 23mm, and the highly practical intermediate 10mm lens, which may be the most frequently used.

We are offering them at a low price due to overseas import. Why not take advantage of this opportunity? If you have a telescope with decent performance, upgrading your eyepieces will undoubtedly enhance its usability and overall performance. (Although new and unused, they have been checked once for quality using a Vixen R130sf.)

The eyepiece diameter is the de facto standard American size (31.7mm/1.25 inch), making them compatible with most major telescope manufacturers such as Vixen.

・Celestron Aspherical 23mm・Apparent Field of View: 62°
This is a versatile lens. For viewing the moon, planets, nebulae, and galaxies where high magnification isn't always necessary, the 62° apparent field of view provides a wonderful sense of openness and a powerful visual experience. Those upgrading from their telescope's included lens will be amazed.

・Celestron Aspherical 10mm・Apparent Field of View: 62°
This is likely the most frequently used lens. After centering your subject with the 23mm, switching to this 10mm allows for detailed observation of lunar craters, Jupiter's rings, and Saturn's rings. For smaller aperture telescopes, the 10mm is ideal for clearly separating the orange and blue stars of Albireo in the constellation Cygnus.

・Celestron Aspherical 4mm・Apparent Field of View: 62°
At this magnification, it's particularly useful for detailed and in-depth observation. For example, with the 4mm, a powerful view of Saturn will fill your vision, allowing you to see surface details, the Cassini Division, and Jupiter's bands with great clarity...
