Astronomy eyepieces are optical components that fit into the focuser of a telescope to magnify the image formed by the objective lens or mirror. This range includes Plossl designs with 4-element optics, aspheric wide-angle models with 58-62 degree fields of view, and Barlow magnifiers with full metal construction. All are compatible with standard 1.25-inch and 2-inch focusers and diagonals. The 1.25-inch models feature multi-coated lenses, blackened lens edges to reduce internal reflections, and include dust covers and rubber eye patches. The 2-inch model has a 56mm focal length and a 47.8mm field diaphragm for wider views.

더 보기What Goes Wrong Without the Right Astronomy Eyepiece
- A telescope with no eyepiece cannot be used for visual observation
- Low-quality eyepieces produce chromatic aberration and edge distortion
- Non-parfocal eyepieces require refocusing when switching between magnifications
- Eyepieces without multi-coating reduce contrast and increase glare under bright skies
- Eyepieces with small field diaphragms limit the visible area of the sky
누가 이 카테고리에서 구매
- Amateur astronomers using refractor or reflector telescopes
- Educational institutions teaching observational astronomy
- Astro-photography setups requiring consistent focus across magnifications
- Telescope dealers offering upgrade kits for existing instruments
- Hobbyists doing planetary or deep-sky observation with standard focusers
왜 이 항목
- Multi-coated 2-element and 4-element optics reduce internal reflections and improve contrast
- Blackened lens edges minimize flare and ghosting in bright or low-contrast scenes
- 1.25-inch and 2-inch barrel sizes fit standard telescope focusers and diagonals
- Plossl design delivers sharp images across the field with long eye relief
- Aspheric wide-angle models offer 58-62 degree fields of view for better sky coverage
- Metal housings with threaded filter rings allow use with standard astronomy filters
- Included dust covers and rubber eye patches protect optics and improve viewing comfort

주문하기 전에
- Confirm the barrel size (1.25 inch or 2 inch) of your telescope focuser before ordering
- Check whether your telescope has a filter thread on the eyepiece barrel if using filters
- Use a 2-inch eyepiece only if your telescope has a 2-inch focuser and sufficient back focus
- Match the focal length to your desired magnification: shorter focal length = higher magnification
- Ensure the eyepiece's field of view matches your observing goals (narrow for planets, wide for deep sky)
자주 묻는 질문
What barrel size do I need for my telescope?
Most amateur telescopes use 1.25-inch focusers. If your telescope has a 2-inch focuser, you can use 2-inch eyepieces for wider fields. Check the diameter of your focuser or diagonal.
Can I use a 1.25-inch eyepiece in a 2-inch focuser?
Yes, a 1.25-inch eyepiece can be used in a 2-inch focuser with an adapter, but the reverse is not possible without a reducer.
Are these eyepieces parfocal?
The 2-inch 56mm parfocal eyepiece is designed to be parfocal. Other models may not be, so refocusing may be needed when switching between them.
Do these eyepieces work with digital cameras?
Yes, the 31.75mm to C-mount adapters allow direct connection of a telescope to a digital camera for imaging.
What is the difference between Plossl and aspheric wide-angle eyepieces?
Plossl eyepieces offer sharp images across the field with 4-element optics. Aspheric wide-angle models have 3 focal lengths (4mm, 10mm, 23mm) and a 62-degree field of view for broader sky coverage.
