You have a telescope but it’s not giving you the night-sky views that you want.
Purchasing an eyepiece could improve how your telescope functions.
What does a telescope eyepiece do?
An eyepiece is important because it collects the light and it also controls your telescope’s field of view and magnification!
If the telescope you purchased isn’t equipped with a high-quality eyepiece, it doesn’t matter because you can change it for something else. Here are the best telescope eyepieces 2023: get more out of your telescope.

Telescope Eyepieces FAQ
Now that you know a bit more about the best telescope eyepieces that are on the market, let’s explore eyepieces in more detail.
Types of telescope eyepieces
You can’t have a functional telescope without the use of an eyepiece that collects light so that you can see what’s in the sky above you. There are many different types of eyepieces available, with different sizes and magnifications.
The two most common eyepiece sizes are 1.25-inch telescope eyepieces and 2-inch eyepieces.
Almost all eyepieces are 1.25-inch, with various lenses and filters being made to thread onto these, therefore proving how versatile they are. As for two-inch eyepieces, they are low-power and wide-field items. They can also be paired with filters and Barlow lenses, though.
The most important eyepiece types to know about are:
1. Huygens and Ramsden Eyepieces
These are usually found in cheap telescopes because they don’t cost a lot of money to produce. Their biggest drawback, however, is that they produce aberrations.
2. Kellner Eyepiece
This 3-lens type of eyepiece has an achromatic lens included to help to prevent color errors.
3. Orthoscopic Eyepiece
This is an eyepiece with four lenses. It’s ideal for viewing the planets and moon because it offers higher levels of magnification.
4. Plossl Eyepiece
This is a well-known eyepiece that has four or five lenses in its design. What makes it so popular is how it enhances color and offers excellent eye relief.
5. Wide-Field Eyepiece
This eyepiece offers a field of view that’s greater than 50 degrees. A type of wide-field eyepiece known as the Naler is considered the gold standard because of how it can deliver 80-degree views and higher, but it is very expensive.
So, which ones should you purchase?
It can feel overwhelming to know what types of eyepieces you will need, but basically, you don’t need that many in order to enhance your astronomy views. A solid collection of the following (via Sky At Night) is more than sufficient for your needs:
- A high magnification eyepiece to zoom into your views. Remember that the smaller the focal length number, such as 10mm, the stronger the magnification!
- A wide/ultra-wide angle eyepiece.
- A medium power eyepiece, such as one that’s got approximately 18mm focal length to improve your views.
- A Plossl eyepiece. This is always a valuable addition to your kit because it offers you wide fields of view.
As an extra note, a Barlow lens is also very useful. It intercepts light inside the telescope so that it can double, or even triple, the magnification of what you get from your eyepiece.
Understanding Telescope Eyepieces
It’s useful to know how telescope eyepieces work and why they’re important. As we mentioned earlier, eyepieces collect light so that you can better see planets and stars when you look at the sky with your telescope.
Some telescopes that you can purchase on the market come with low-quality eyepieces, but when you change them, you’ll be quite surprised at the difference in what you can see.
While there’s always an emphasis placed on choosing the best telescope for your astronomy needs, the eyepiece is the component that really makes a difference in how well the telescope can work.
It’s important to note what the different magnifications of eyepieces do, so let’s look at high-, medium-, and low-power eyepieces in a bit more detail.
This enables you to view larger celestial objects, such as planets, and frame many of them in a single view. You could find one that’s about 40mm focal length to help you achieve these goals.
This eyepiece lets you see many more details, such as the planets and star clusters. When you increase the magnification of your eyepiece, this has the effect of making the sky darker to improve the contrast of your views. An example of a medium-power eyepiece is a 32mm focal length.
This one is obviously focused on letting you see even more details in space objects, so you’ll want to reach for it when you view the planets through your telescope. An eyepiece with a focal length of 15mm will be considered a high-power one.
Cleaning your telescope eyepieces
When cleaning your telescope eyepieces, you need to be really careful so that you don’t damage their coating.
A quick and easy way to eliminate dust from your eyepiece before using it is to brush it with a photographic-grade camel hair brush which you can purchase from camera shops. The camel hair is soft, so it won’t scratch your eyepiece.
If there are marks or stains on your eyepiece you wish to remove, an excellent product is the Lens Pen. It makes use of a carbon formula instead of liquid in a pen-like structure, enabling you to easily wipe away stains from your eyepiece without leaving residue behind.
Another effective way to clean your telescope eyepiece is with the use of a can of compressed air. This will blow away any dust and debris from the surface of the eyepiece.
This is important to do before you clean the eyepiece with a liquid; otherwise, those particles can scratch the eyepiece coating.
After using the compressed air, you should dip a cotton ball in a solution of isopropyl alcohol. Carefully swipe it across the eyepiece lens, being careful not to rub it back and forth as that can cause scratches on it.
Once you’re done, you can use a second dry cotton ball on the lens. If the cotton ball has left behind a bit of fluff, you can remove it with the camel brush or compressed air.
Prevent dirt from accumulating on your eyepieces in the future so that you don’t have to clean them by storing them in a sealed container that won’t collect dust. You should also make sure you avoid handling the eyepieces as much as possible.
Wear gloves when touching them to prevent fingerprints on them. The oils in the skin can lead to residue and cause stains to form on the eyepiece lens, so you want to avoid touching them as much as possible!
Should you buy used telescope eyepieces?
Eyepieces can be expensive, so you might want to consider purchasing second-hand ones to save some money. There’s nothing wrong with this, provided that you ensure that the eyepieces are in good condition.
It’s always a good idea to check the eyepieces before you purchase them. You want them to have covers; otherwise, that could point to how they weren’t properly looked after by their previous owner.
As a result, they could be dirty (which means you’ll have to clean them), or the accumulation of dust and dirt could have caused them to become scratched.
There are some excellent places where you can purchase second-hand eyepieces (as well as other astronomy gear), such as High Point Scientific.
Here, all the gear and accessories are put to the test to ensure they perform optimally – and there’s a return policy in place! Another website to check out is Woodland Hills Telescope. They have a variety of brand-name telescope eyepieces for sale.
What about private sellers?
Even though you can find some of the best budget telescope eyepieces that aren’t brand new from individual sellers, it’s worth bearing in mind that a private sale could cause you to miss out on benefits such as warranties and the chance to return your eyepiece should something go wrong, which is why it’s important to use a reputable company.
Choosing a reputable retailer usually also means that you can take advantage of their trade-in programs. When items are taken in by the company to be resold, they will be tested to ensure that they perform well.
You can’t always be guaranteed that the private seller who wants you to buy their eyepieces took good care of them or even that they work, so if you want to purchase second-hand astronomy gear, stick with reputable companies.
Now that you’ve read this article and our best telescope eyepieces reviews, you have a much better idea of why eyepieces are so important and why you should add more of them to your astronomy collection!
