Using one of the best eyepieces for telescopes will optimize your instrument's optical prowess and make skywatching even more enjoyable for astronomers, more so than a telescope with a substandard eyepiece would.
Sure, the telescope might be the most expensive item in your stargazing gear collection, but investing in high-quality accessories can significantly enhance your stargazing experience. Among these accessories, a good eyepiece is one of the most crucial investments you should consider. It will open up a whole new world of celestial wonders and make your stargazing sessions even more immersive and enjoyable.
Many high-quality eyepieces are available for viewing stars, planets, galaxies and other celestial objects. While the aperture of the telescope itself is a significant factor in determining what you can see, eyepieces also play a crucial role.
Not sure what eyepieces are or do or why having a good one is necessary? Scroll to the end of this guide to discover what to look for when selecting a telescope eyepiece. If you haven't invested in a telescope yet, you need to make that choice first — if that's the case, start by looking at our Best telescopes, Best telescopes for beginners, or Best telescopes for kids.

✅ You want the best bang for your buck: While buying the set is substantially more expensive than just buying one or two individually, you'll save money if you want all the focal lengths in the set.
❌ You're on a budget: While you do save money buying the set than purchasing each one individually, it's a pretty hefty initial investment, so not particularly accessible if you're on a budget.
🔎 Baader Hyperion Eyepiece set with hard case: Highly regarded by astronomers for its surprisingly excellent build quality and incredibly high-quality optics, including multi-coated lenses. ★★★★½
Baader is a well-known brand for producing high-quality products. This complete eyepiece set is no exception and offers excellent value for money. Amateur astronomers highly regard this set for its surprisingly excellent build quality and high-quality optics, including multi-coated lenses. While a sizeable initial outlay, this set offers excellent value for money, about half the price per eyepiece than the Tele Vue Nagler range we just mentioned. They are available to buy as individual eyepieces too should you want only part of the seven-piece set.
This set of eyepieces includes a variety of focal lengths, ranging from 5mm to 24mm. Their barrel design allows them to fit both 1.25-inch and 2-inch focusers, which is very convenient. The eyepieces also provide a comfortable 20mm eye relief, making them great for people who wear glasses or enjoy long viewing sessions. What's more, they offer a wide 68-degree apparent field of view (FOV), allowing you to see more of the sky in one glance, making them suitable for all types of observations.

Best for range of choice
✅ You're on a budget: For a four-element 1.25-inch eyepiece, they're incredibly affordable and good value.
❌ Your want to view deep sky objects: They are usable for deep sky viewing, but their narrow field of view doesn't make them the ideal choice for that. They're better for lunar and planetary observations.
🔎 Celestron Omni Plossl Eyepieces These are a fantastic entry-level range into the high-quality Plossl design. They're excellent quality, especially given the price, and provide excellent planetary and lunar views. ★★★★
The Celestron Omni Plossl eyepiece range offers an excellent entry-level range into the higher quality 4-element Plossl design. We think they are of fantastic quality given the price of less than $50 per eyepiece, and they're much cheaper for the shorter focal lengths.
While we understand that appearance isn't everything, these eyepieces do have a stylish and premium look. They feature a glossy aluminum finish on one half of the barrel and a sophisticated matte gray finish on the other. But it's not all about looks; each element of the design is carefully crafted to reduce distortions and color fringing, known as chromatic aberration. The inside of the barrel is also black, which helps minimize internal reflections for better clarity in your celestial observations.
The range comes in focal lengths of 4mm to 56mm, all in 1.25-inch size, aside from the 56mm eyepiece, which comes in a 2-inch size. These eyepieces produce sharp images, especially on the axis, and are best suited to planetary observations. Their narrow apparent field makes them usable for deep sky observation but not the best choice. The eyepieces are all supplied with a dust cap over the barrel and an objective lens.

Best for eyeglasses
✅ You wear glasses: They have 12-27mm eye relief, making them comfortable and convenient for anyone who wears glasses.
✅ You want to view a range of subjects: They're great for viewing the moon and planets, but will also serve you well when you're exploring galaxies and nebulas, too.
❌ You're on a budget: They're on the more expensive side, especially the 2-inch sizes, so if you're on a budget we'd suggest a different design.
🔎 Celestron Luminos Eyepieces They're high quality, are designed well and provide excellent views of the moon, planets, and deep-sky objects like nebulas and galaxies. They have generous eye relief and multi-coated lenses. ★★★★
The Celestron Luminos eyepiece range represents the replacement for the now discontinued but previously popular Axiom eyepieces.
The Luminos eyepieces are an upgraded, high-end design that are still lighter than the previous range they replace. They come with twist-up eyecups and a parfocal eyepiece, which means you won't need to refocus much when switching between low and high-power views. Each eyepiece has multi-coated lenses to enhance light transmission and blackened edges to prevent light from leaking out of the sides of the barrel. These features contribute to a better observing experience with improved image quality.
The comfortable eye relief and ultra-wide apparent field of view of 82 degrees (the same as the expensive Tele Vue Nagler range) provide a large and immersive view of your target object. The eyepieces in this range are ideal for viewing large subjects like the moon and planets but will also serve you well when scoping out galaxies and nebulas.
We must mention that some sizes (19mm, 23mm and 31mm) are only available for 2-inch barrel sizes.

Best for planetary observations
✅ You're focusing on viewing planets: These eyepieces are widely considered to be the best for planetary observation and have earned a reputation as such.
❌ You want to do deep-sky viewing: Their narrow field of view means they aren't suitable for deep-sky viewing.
🔎 Takahashi Abbe Orthoscopic Eyepieces For planetary viewing, these are considered to be the very best available, but their field of view is too narrow for deep-sky viewing. ★★★★
Takahashi is a well-known brand for producing optics of the very highest quality. Their Abbe Orthoscopic eyepiece range has become almost legendary among planetary observers, and these eyepieces are widely considered among the very best available for that purpose. They are fully multi-coated for maximum light transition and increased contrast.
They come in a wide variety of focal lengths, making them compatible with almost any telescope. However, it's important to note that their narrow apparent field of view, measuring 44 degrees, means they are not suitable for observing deep sky objects. On the other hand, this narrower field of view makes them well-suited for observing the Moon and planets, allowing you to focus in on the details of celestial bodies.

Best for high power observing
✅ You want to observe the planets: These large magnification eyepieces are ideal for observing the moon and planets.
✅ You wear glasses: They feature a generous 16mm of eye relief, making them comfortable for anyone who wears glasses.
❌ You want twist-up eyecups: These have fold-up eyecups, whereas the pricier X-Cel versions have twist-up eyecups.
🔎 Celestron X-Cel LX Eyepieces We think this is a good quality, reasonably-priced choice that's definitely worth considering. They are well suited to high-power observing and the image quality is great. ★★★½
The seven focal lengths available in this range are well suited to high-power (large magnification) observing, such as lunar and planetary. That said, the apparent field of view is a wide 60 degrees — this is perfect for quickly finding your way around the sky.
The image quality of these eyepieces is great, with sharp and well-corrected views. They also offer a generous 16mm eye relief, making them comfortable for people who wear glasses and perfect for extended skywatching sessions. The pricier X-Cel versions come with twist-up eyecups, while this version (indicated by 'LX' at the end) has fold-up eyecups.
Additionally, the lenses are fully multi-coated, which means they have multiple layers of coatings on all air-to-glass surfaces. This coating helps reduce reflections and improves the transmission of light, resulting in clearer and brighter views through the eyepieces.
The external bodies are stylish black-anodized aluminum with the orange detailing we've come to know and love from Celestron. The interior of the eyepieces is also black to reduce internal reflections further. A rubber grip around the middle of the barrel provides a secure grip, so you're less likely to drop them when swapping between eyepieces, which is especially useful if you're wearing gloves. Overall we think this is a good quality, reasonably-priced choice that's definitely worth considering.

Best eyepieces for telescopes FAQs
What is a telescope eyepiece?
Telescope eyepieces are small, hand-held lenses that we place at the telescope's focus to bring the image into sharp focus for our eyes to observe. They are available in a variety of different types and designs. They also come in various focal lengths, determining the effective magnification. Focal lengths of anywhere between 3mm to 50mm are widely available.
What types of telescope eyepieces are there?
Various lens designs are widely used for telescope eyepieces — Plossl, Kellner, Orthoscopic and Radian are the most popular. A number of companies today also offer multi-element designs on a custom basis.
What size eyepiece do I need for my telescope?
There are three popular sizes of eyepiece barrel diameters: 0.96-inches, 1.25-inches and 2-inches. Almost every telescope can accept eyepieces of one of these sizes. The 1.25-inch size is the most widely used among manufacturers. Check your manual to see which size your telescope is compatible with.
Do I need anything else besides a telescope eyepiece to view the stars?
Yes. You will need a telescope and a tripod in order to view the night sky. We have plenty of guides and pages available to help you pick the right product. Looking for a telescope? Try our guides to the Best Telescopes, Best telescopes for beginners and more niche instruments like the Best telescopes to see planets or the Best telescopes for deep space.
Or seek out the latest deals with our pages on Budget telescopes under $500 or the Telescope deals page.
What do telescope eyepiece numbers and terms mean?
Here is a basic telescope glossary that explains the most common terms and numbers:
Focal length — The eyepiece's focal length (usually measured in mm) The larger the number, the lower the magnification it will provide (the subject will not appear as close up).
Barrel diameter — Eyepieces come in 0.96-inch, 1.25-inch or 2-inch barrel sizes.
Magnification — The power the eyepiece provides with your telescope (this will vary depending upon the telescope.)
Apparent FOV — The apparent field of view is measured in degrees. In general, eyepieces with a large apparent field will cost significantly more but provide an almost '3D-like' viewing experience, especially for deep sky observing of extended objects. A wider field of view allows you to see more of the sky at once.
Eye Relief — Usually described in mm, this tells you how far your pupil must be from the rear element of the eyepiece to see the entire field of view. A longer eye relief gives a more enjoyable viewing experience, especially if you wear glasses where you physically won't be able to get your pupil as close as non-spectacle wearers.
Exit Pupil — The figure (also usually in mm) describes the size of the light cone at the eye relief position. Our dark-adapted pupil is never larger than 7mm, so any exit pupil size above this level is wasted light.
Coatings — Eyepieces with multi-coatings offer better contrast and brightness than eyepieces with no coatings.
