The 13 Best Telescope Eyepieces &
There’s nothing quite like the feeling of receiving and unboxing a brand new telescope. Whether it’s your first one, or an upgrade, it’s great to get a piece of equipment that will help reveal the deeper wonders of the night sky. But unfortunately – especially with lower-cost telescopes – most telescopes come with just one or two mediocre eyepieces that limit the true power of your scope. That’s where upgrading to one of the best telescope eyepieces out there can help; you’ll see more, and you can actually save money overall by not needing to upgrade your whole telescope.
In this post, I’m breaking down what to look for in telescope eyepieces and the best telescope eyepieces and multi-eyepiece kits. The products recommended below are among the best in the market, and range from affordable to splurge-worthy.
No matter what stage of astronomy enthusiasm you’re in, a good telescope eyepiece is critical to a great night of stargazing. Read on and you’ll know everything necessary to make an informed decision and see solar system and deep space objects further, clearer, and brighter than before.
What to Look for in a Great Telescope Eyepiece
You might have heard (or maybe experienced it yourself) stories of people looking through less powerful telescopes and finding that these deliver jaw-dropping views of the night sky. This happens due to one little component: a better eyepiece. When stargazing, there are lots of factors that affect your experience; the eyepiece is a key one because it defines the magnification power and field of view of that telescope.
However, finding the right eyepiece is no piece of cake. Below, you’ll find a quick guide with the most important factors you have to take into account when buying your next eyepiece.
1. Types of telescope eyepieces
Below you will find the various eyepieces found in the market. We’ve added a small description of each one for you to know them better.
- Plossl – This is the first type of eyepieces newbies get in contact with. They’ll most likely come free with your telescope.
- Kellner (achromatic) – these eyepieces are very similar to Plossls.
- Orthoscopic – These are popular for their superior image quality even on edges and large eye relief. Sadly, these eyepieces feature the smallest apparent field of view, so you are not getting much of the surrounding area.
- Aspherical – This type of eyepiece is the best buy: they are cheap and have good image quality with a decent apparent field of view.
- Ethos, Nagler, Delos – These eyepieces are as good as it gets. Their higher design, image quality, and large apparent field of view make them extremely superior to the low-end pieces. Being 10 to 15 time more expensive than low-end eyepieces, the price is steep to say the least.
- Zoom eyepieces – Not the best eyepieces on the market. They tend to have an apparent narrow field of view and when you change their focal length (magnification), you must refocus the image.
- Planetary eyepieces – These eyepieces are low on light. It means you can observe only the brightest objects like the planets, the Moon, and double stars.
The second thing to look at in the quest for the best telescope eyepieces is the diameter. To make things simple, diameter refers to the physical size of the eyepiece barrel (the silver part that inserts into the eyepiece holder). Today, there are 3 standard sizes of eyepieces in use for amateur telescopes: .965”, 1.25”, and 2″. The 1.25″ is the most common size of the three used in amateur telescopes. While the 2″ is also common, this size is generally found on larger, more advanced telescopes. As for the .965″ size, this is an older obsolete size, but can still be found on some entry-level telescopes. To know which eyepieces you can use, take a look in your manual or user’s guide.
3. Eye Relief & Exit Pupil
You certainly have seen these words in most telescopes’ descriptions. Both eye relief and exit pupil are related to the comfort and head position you’ll hold while stargazing. The eye relief is the maximum distance you can place your eye from the eyepiece lenses while focusing on the full field of view.
The exit pupil is the diameter of the beam of light that projects from the eyepiece into the entrance pupil of your eye. This is important when you observe the faintest deep-sky objects since you need all the gathered light to be projected onto your retina through your widely dilated pupils.
4. Apparent Field of View and True Field of View
In stargazing, the apparent field of view refers to the width of the sky presented to your eye. In other words, it refers to the portion (how much) of the sky you’ll be able to see: the larger the number, the larger part of the sky you can see. You can find eyepieces with apparent fields of view ranging from around 30 degrees (quite narrow) to over 80 degrees (extremely wide), with the most common one ranging from 40 to 50 degrees. The true field of view refers to the amount of sky you can really see through an eyepiece once it’s been attached to the telescope. It’s calculated by dividing the Apparent Field of View (AFOV) by your telescope’s magnification.
5. Focal length
Knowing the focal length of a telescope is crucial because it is directly related to the magnifying power of a telescope.
The focal length is essentially the distance (in millimeters) that light travels inside the telescope from its entry point (the aperture) to the exit point (the focuser where you place your eyepiece.) You can find the focal length of your telescope on a label usually placed on the tube. Once you know the focal length, you can calculate the telescope’s magnification using this formula: focal length telescope / focal length eyepiece.
From budget-friendly to skyrocketing prices, telescopes can be found in all price ranges. We’ve divided telescopes into three categories: under $100, between $100 and $250, and over $250.
Low-cost or budget eyepieces typically range under $100. Still, thanks to modern design and manufacturing methods there are some very good choices in this range.
Eyepieces between $100 and $250 come closer to high-end brands. They usually have more features, a better build, and are a bit more polished.
Finally, the eyepieces over $250 are the best of the best, regarding optics and quality. Once you go over this price range, eyepieces can cost as much as $1000 each.
Extra tip: Your eyepieces do not need to be the same brand as your telescope. There is no problem using a Tele Vue eyepiece in a Celestron telescope, for example.
