• Extra-Low Dispersion ED Glass reduces chromatic aberration which causes color fringing and produces a cleaner and brighter image;
• Large field of view; 42mm objective lens provides a field of view at 394ft/1000yards;
• IPX7 waterproof through nitrogen-filled internals to handle the most extreme weather conditions; ensuring you can watch uninterrupted views;
• Premium coatings provide a high light transmittance across the entire visible light spectrum; guarantee a bright; sharp image even in twilight conditions by maximizing transmission of fading light;
• High-quality Magnesium alloy body allows a long term use;
• Large central focusing wheel for easy focusing; easy to operate; just turn the focusing knob to get clear and sharp images;
• Diopter adjustment; eyepiece built-in diopter adjustment lens; can adjust the visual balance of both eyes; easy to observe the target.

It's no surprise that the eyepieces in our Sirius Plossl line are our best-selling telescope eyepieces. Quality this good usually costs a lot more.

Offering a wide 52° apparent field of view, this 25 mm Orion Sirius Plossl Telescope Eyepiece provides extremely sharp images of impressively high contrast. It's ideal for all types of telescopes: reflector, refractor, and catadioptric. The Plossl 4-element design is renowned for its outstanding performance, and has become the standard by which all other telescope eyepieces are judged.

The Sirius Plossl optical system is multi-coated for excellent light transmission and bright views. Lens edges are blackened to reduce scattering of stray light and maximize contrast.

The lenses are mounted in black-anodized aluminum housings with a 1.25"-diameter chrome-plated brass barrel for durability and precision fit. The barrel is internally threaded to accept standard telescope filters. The built-in rubber eyeguard enhances viewing by helping to block out ambient light and position the eye.

This 25 mm eyepiece excels for moderately low power scanning of open star clusters and viewing of extended nebulas and larger galaxies.

• Help you watch the moon comfortably; The 1.25" Neutral Density Moon filter can reduce the amount of light reaching the film without affecting the color; and reduces glare so you can see more lunar detail and surface features with your telescope
• Durable Material; The included filters are made of HD optical glass; Good level of transmittance; Aluminum alloy frame sealing ring for better tightness; avoiding fall or loose
• Protect vision; ND4 filter transmits only 25% of the incoming light; help reduce radiation; reduce deformation between light and dark areas at the edge of the moon; help protect dark-adapted vision when viewing the moon's surface
• Suitable for watching the crescent moon; As the Moon moves around the Earth; we get to see more and more of the illuminated half; and we say the Moon is waxing; At first we get a sliver of it; which grows as days go by; This phase is called the crescent moon; It's very good effect to use the ND0.6 filter at this time
• Applicable standard 1.25 inch; Metal filter cell threads directly into the 1.25 inch barrel of your telescope eyepiece; Let you achieve a sharper image directly; Useful for different caliber astronomical telescopes through which the light of the Moon can be extremely overwhelming

Canon camera adapters with M42 or wide M48 female thread, using these Canon EF-mount Adapters, you can connect the telescope with your Canon cameras.

After years of R&D we have developed a new solar film that has the optical quality of glass with the advantages of impregnated polymer. Will never develop pinholes or scratches that can let in light and ruin a filter. Other advantages: lightweight and does not require re-balancing tube assembly, will not break, consistent yellow-orange solar image, even density with any aperture, flat surface compared to other thin film filters that have wrinkles and creases. Will not tear or puncture. Stronger than any other solar film on the market. Also available in sheets. Guaranteed 15 years.
