Users will experience incredible views without breaking the bank or impinging on your telescope's balance. They represent what is perhaps the best buy today for astronomers on a budget or for beginners. But don't be fooled by their low prices - these might well turn out to be all the eyepieces you will ever need!
The Bintel Plossls are available in a 1.25" barrel size and 9 different focal lengths ranging from 6mm to 40mm. The 4mm, 6mm and 9mm models are great for high power planetary and lunar observation. The 12mm and 15mm are perfect intermediate focal lengths, performing well on both deep-sky and planetary subjects. The 20mm and 25mm models would be excellent choices for low power scanning of open star clusters and viewing larger galaxies. The 32mm and 40mm models offer a wide field and are superb for wide field scanning, detailed observations of large diffuse subjects or as a finder eyepiece.
- All eyepieces are fully multicoated (FMC) for maximum light transmission
- High quality lenses provide the best-possible sharpness all over the field of view
- Blackened lens edges reduce light scattering and improve contrast
- Fold-down rubber eyecups to keep out stray light
- Comfortable eye relief at all but the shortest focal lengths (As in all Plossl eyepieces, eye relief can get tight at the shorter focal lengths but this is design constraint, not a fault of these eyepieces)
- Includes two end caps
- 50 Apparent field (degrees)

saxon Plossl eyepieces can be used on all types of telescopes - refractors, reflector, and catadioptrics such as Celestron SCT telescopes.
Featuring a 4-element design, this Plossl eyepiece ensures maximum light transition, minimises spherical aberration, distortion, astigmatism, and off-axis colour. The edge-to-edge blackened optics provide excellent contrast across the 52° apparent field of view.
This 32mm size will offer a lower magnification than the 25mm size provided as standard with most telescopes. It's a handy way to obtain a wider field of view for large deep-sky objects including many nebulae and star clusters.
The oversized optical elements provide long eye relief while stray light is eliminated by the fold back rubber eyecups.

This 15mm size offers a mid range magnification between the 10mm and 25mm sized eyepieces provided as standard with most telescopes. This mean more flexibility to find just the right size for observing the Universe.

This wide-angle 14mm Nikon eyepiece combines a flat, wide field of view with a high eyepoint for easy viewing. The rubber eyecup and light-blocking hood make it easy to look through and block out ambient light, allowing you to enjoy astronomical observation in comfort.
Main Features
- With an apparent field of view of 72°, you can enjoy a wider actual field of view at the same magnification, allowing you to enjoy the impressiveness of outer space.
- Rather than focusing on numerical values, the eye relief is designed with performance as the priority, and the lens barrel is designed with ease of use in mind, ensuring a nearly constant distance from the end of the eyepiece to the eyepoint. Furthermore , exit pupil aberrations are effectively eliminated, minimizing blackout and coloration when the eye moves away from the eyepoint, improving usability.
- This advanced optical design combines a wide field of view with a flat image. It is compatible with the brightest F-numbers of the astronomical telescope objective optical system it is paired with. The NAV-14SW especially is compatible with optical systems up to f/4. It improves the peripheral image without compromising the central image, minimizing field curvature and astigmatism.
- To eliminate stray light that is harmful to observation, light-shielding diaphragms, light-shielding wires, and black paint are used in appropriate locations, and the lens surfaces are multi-coated to reduce harmful reflections and improve transmittance, among other measures.
- The mounting diameter is 31.7mm or 1.25", the standard "American size." It can be used with various telescopes. It also features a parfocal design, with the flange at the focal point. *Please make sure the eyepiece insertion diameter of your telescope is 31.7mm.
- The eyecup rubber that comes into direct contact with the skin is made of skin-friendly silicone rubber, and features an easy-to-grip knurled design reminiscent of Nikkor lenses.
- A silicone rubber light-shielding hood is used to prevent external light disturbances when observing at high magnifications where close contact is not possible, or in places such as parking lots. Unlike the usual "horn-shaped" hood, it has a unique shape that can be used by people who wear glasses, and is flexible enough to reduce the transmission of vibrations. It is detachable and can be removed when not needed.Â
- Drip-proof construction with rubber sealing to prevent night dew from seeping in.
- The optional TSA-1 telescope attachment allows for digiscoping. The FSB series compact digital camera bracket allows for collimated photography. It can also be used for lunar and planetary photography, expanding the scope of your photography.
- The innovative eyepiece converter "EiC-16" (sold separately) enhances the performance of NAV-SW eyepieces. The "EiC-16" converts the magnification to 1.6x. Unlike conventional Barlow lenses, the optical design optimized for the NAV-SW series increases magnification without sacrificing sharpness in the centre, further improving image flatness. The mounting system is a 31.7mm/1.25" chuck with minimal decentering error.

High-performance wide angle eyepieces for ultra clear astronomical viewing - 85° Apparent Angle of View
The PENTAX XW series 85° Apparent Angle combined with 20mm of Eye Relief produces some the widest and most relaxed viewing possible with your telescope.Â
High-Grade Optics for Exceptional Image Quality
The high-performance XW-series optics incorporates high-refraction, extra-low-dispersion lanthanum glass elements to produce a well-balanced image with minimal aberrations. It is particularly designed to reduce the disturbing blackout effect by effectively compensating the spherical aberration of the pupil.
PENTAX-Original Multi-Layer Coating for Outstanding Light Transmission Efficiency
All lens surfaces that come in contact with air are treated with the original multi-layer coating, while all laminated surfaces are treated with the innovative partial coating, to offer the light transmission efficiency of more than 90 percent (an astonishing 96 percent at 550nm) over the visible light spectrum.
Advanced Light-Shielding Technology for Improved Image Contrast
Thanks to PENTAX’s advanced computer simulation technology, the XW series features a light-shielding diaphragm at the most effective position to drastically reduce internal reflections for a brighter, higher-contrast image.
Sleeve Size and Eyecup Design
The XW series provides a choice of two diameter to suit practically all telescope fousers: American-standard 31.7mm version (1.25"), and 50.8mm (2") version.
 When you remove the screw-on eyecup, it also provides a screw thread with a 43mm diameter and a 0.75 pitch
