Telescope Eyepiece FAQ

If you want to purchase an eyepiece or eyepiece kit for your telescope, chances are you have some questions about eyepieces in general. Let’s check them out so you can find the best product for your needs and also learn about the best way to use it. 

What does the eyepiece do on a telescope?

A telescope eyepiece is the part of the telescope that brings all the light that the telescope has collected to your eye. It therefore has a crucial role to play in what you get to see when you point your telescope to the sky.

Don’t underestimate the value of a good eyepiece as it can totally change how you experience using a telescope. When you replace a low-quality eyepiece with a higher-end one, the difference can be amazing. In this way, the eyepiece can feel like you’ve given your telescope a completely new lease on life! 

The sad reality is that even if you have a telescope that has a high-quality mirror or lens on it, it won’t be able to acquire exceptional focus unless you use a high-quality eyepiece on it. Period.

This feature is not only important if you’re using your telescope to view celestial objects but it’s also important if you’re keen on taking images of what you see so that they will be of excellent quality and free of issues such as blurriness.

There are some valuable eyepieces you should own if you want to take your astronomy to the next level. These include:

A low-power, wide-field eyepiece

This type of eyepiece will enable you to see large celestial objects. It will also mean you can frame many objects in one view, while locating objects in the sky before you switch to a higher magnification very easily.

An example of a low-power eyepiece is one that’s got a 40mm focal length.

A medium-power eyepiece

This brings details out to shine, like when you view galaxies and star clusters. It can also increase the magnification of small objects.

On the other hand, using more magnification will make the background of the sky much darker to boost the contrast in the image so you can better see the celestial gems. A 32mm focal length eyepiece will be considered one with medium power.

A high-power eyepiece

This type of eyepiece will ensure you can see more details, but it’s especially useful for seeing the moon and planets. A high-power eyepiece will have a lower focal length, such as 15mm.

What to consider when buying a telescope eyepiece?

Based on the above, you might be wondering what you should look for in a quality telescope eyepiece. Here’s a list of important elements that you should note so that your telescope will work better than ever before. 

Focal Length

Eyepieces have different focal lengths, such as 10mm or 25mm. Focal length is important because it’s basically the distance from the main part of the eyepiece where rays of light converge to a single spot.

When combined with the focal length of your telescope, this determines your magnification.

It’s probably a good idea for you to start with a focal length of about 25mm to help you see the celestial objects in your field of view and then you can upgrade to a higher power, such as 15mm.

If you see improvements, then you should move to a higher power again. Doing this enables you to find what Opt Corp calls the “sweet spot” of visible details, brightness, and image scale.

Long/Short Eye Relief

Eye relief is an important feature to look for in a telescope eyepiece.

If the relief is low, such as 10mm, then wearing eyeglasses while looking through the telescope won’t give you the complete view in front of you simply because the glasses extend beyond 10mm in front of your eyes.

Even if you don’t wear spectacles, not having good eye relief can make using the eyepiece exhausting. Choose an eyepiece with at least 15mm so that it will be more comfortable.

An example of an eyepiece that has good eye relief is the Celestron Zoom Eyepiece on our list of reviews, which is said to have between 15mm and 18mm of eye relief.

Apparent Field Of View

The Apparent Field Of View of your telescope eyepiece is the angular diameter of light that you can see via the eyepiece. A good rule to follow with this feature is that versatility is key.

You should aim to use anything lower than 40 degrees (which is narrow) to view the moon or planets, while 80 degrees (which is wide) and higher is suitable for seeing deep-sky objects, such as galaxies.

What is a Barlow lens?

As we’ve seen in the best telescope eyepieces reviews, some eyepiece kits will also contain a Barlow lens. Why is this such a revered lens in astronomy?

Here’s the lowdown.

A Barlow lens has a concave lens that’s put between the telescope’s objective lens (or mirror) and the eyepiece. This is so that the lens can achieve its main function: magnification! A Barlow lens essentially helps to magnify whatever you’re looking at by double or even triple.

Although you might think that Barlow lenses are similar to zoom lenses, there are some crucial differences. For starters, Barlow lenses have a magnification level that’s fixed.

They also provide a smaller field of view as compared to zoom lenses. Another difference is that Barlow lenses are lighter than zoom lenses, as the latter tend to have a blend of multiple glass elements which can make them heavier.

One of the best things about using a Barlow lens is that by magnifying what you see, it’s like you’re increasing the number of eyepieces you own.

This also has a practical convenience – you don’t have to switch to a different eyepiece when you want to magnify what you’re seeing through the telescope.

What is the difference between 1.25” eyepiece and the 2” eyepiece?

Earlier, we talked about how 1.25-inch eyepieces are sort of the standard, but how are they different when compared to two-inch eyepieces?

First of all, you’ll find that 1.25-inch eyepieces will be found on entry-level telescopes but you can use 1.25 or 2-inch eyepieces on intermediate and advanced telescopes, thus making them more versatile.

Here are some other differences between 1.25-inch and 2-inch eyepieces.

1.25-inch eyepieces are lighter and smaller while also being less expensive. We can see this with the Celestron 1.25” Eyepiece and Filter Accessory Kit that we reviewed in our list of best quality telescope eyepieces.

These eyepieces also provide you with a bit more versatility, such as when it comes to short focal lengths.

2-inch eyepieces, on the other hand, have large ocular lenses which can be more comfortable to use.

They also give you a wider apparent field of view when focal lengths are greater than 32mm. However, you can also make use of focal lengths that are greater than 40mm, which is good if you want to find celestial objects.

There’s really no right or wrong when choosing between the two types of eyepieces. It really comes down to your personal preferences.

What is the use of a color filter?

WHAT IS THE USE OF A COLOR FILTER?

As we’ve seen in our list of the best value telescope eyepieces, some eyepiece kits come with color filters included, sometimes five or six. But what does a color filter actually do?

You might be wondering this if you’re new to using a telescope.

Put simply, color filters help you to see more details when looking at the moon and planets. Filters of different colors will help you to see different things and different filters are meant for viewing different planets.

For example, a yellow filter on your eyepiece can help you see Mars’s craters in more detail while increasing the details you will be able to see on Jupiter’s belts. It can also boost the orange and red colors on both Saturn and Jupiter.

On the other hand, a red filter will help to create more contrast in the dust clouds on Mars, and it has the benefit of decreasing light glare when you view Venus. This shows that color filters can have purposes other than helping you to view planets in greater detail!

What about other filter colors?

  • Orange filters can be used to boost contrast between dark and light areas, and they also detect dust storms on Mars as well as sharpen Jupiter’s contrast.
  • Blue filters bring out details in atmospheric clouds and also darken any red areas on Mars. Dark blue filters can be useful when you want to boost contrast, such as on planets like Venus and Jupiter when you want to see more details.
  • Violet filters. These are mainly reserved for larger telescopes. Violet filters boost contrast in celestial objects such as Saturn’s rings, but they can also be useful when you want to decrease glare to better see planets such as Venus.

Conclusion

You already own a telescope, but are you sure it’s allowing you to see the most amazing views of the sky?

If not, then you need to upgrade your telescope with the use of an eyepiece.

In this article, we’ve featured the best telescope eyepieces for the money that you should purchase, looking at important information such as their pros, cons, and cost, so you can choose the one that will take your astronomy and astrophotography to the next level.

We’ve also featured some important information about eyepieces, color filters, and more, so that you’ll know which items to look for in your telescope eyepiece kit and which ones you don’t need during your next backyard stargazing hunt!
