Best Telescope Lens to View the Moon: Our Top Picks

If you’re interested in viewing the moon through a telescope, you may be wondering what type of lens is best for the job. The answer to this question depends on a few factors, such as your level of experience with telescopes and your budget. However, there are a few general guidelines you can follow to help you choose the right lens.

First, it’s important to understand that the moon is a bright object, so you don’t necessarily need a high-powered lens to view it. In fact, a low magnification lens (around 50x) will allow you to see the entire moon and get a sense of its overall shape and features. However, if you want to see more detail, you may want to invest in a higher magnification lens.

Another factor to consider is the type of telescope you have. Refracting telescopes (which use lenses to gather and focus light) generally provide sharp, clear images of the moon, so you may not need as high of a magnification lens with this type of telescope. Reflecting telescopes (which use mirrors instead of lenses) can be a bit trickier to use, but they can also provide excellent views of the moon with the right lens.

Understanding Telescope Lenses

Types of Telescope Lenses

When it comes to viewing the moon with a telescope, the lens you choose is crucial. There are two main types of telescope lenses: eyepieces and Barlow lenses. Eyepieces are the most common type of telescope lens and come in a range of focal lengths. The focal length determines the magnification of the image you see. A shorter focal length eyepiece will provide higher magnification, while a longer focal length eyepiece will provide lower magnification. Barlow lenses, on the other hand, are used to increase the magnification of an eyepiece. They work by extending the focal length of the telescope, effectively increasing the magnification of any eyepiece used with it.

What to Look for in a Telescope Lens

When choosing a telescope lens for viewing the moon, there are a few key factors to consider. Firstly, consider the aperture of your telescope. The aperture is the diameter of the telescope’s primary lens or mirror and determines how much light the telescope can gather. A larger aperture will allow for more detail to be seen on the moon’s surface. Secondly, consider the focal length of the lens. As mentioned earlier, the focal length determines the magnification of the image. It’s important to choose a focal length that will provide the magnification you desire while still maintaining image clarity. Lastly, consider the quality of the lens itself. Look for lenses made from high-quality materials and with good coatings to reduce glare and improve contrast. In conclusion, when it comes to viewing the moon with a telescope, the lens you choose is crucial. Consider the type of lens, the aperture and focal length of your telescope, and the quality of the lens itself when making your choice.

Choosing a Telescope Lens for Lunar Observations

When it comes to observing the moon through a telescope, the right telescope lens can make all the difference. In this section, we’ll explore the factors to consider when choosing a telescope lens for lunar observations and recommend some of the best lenses for the job.

Factors to Consider

Before selecting a telescope lens for lunar observations, you should consider several factors:

  • Magnification: For lunar observations, a magnification of 100x to 200x is recommended.
  • Aperture: A larger aperture will provide a brighter and clearer image of the moon.
  • Focal Length: A longer focal length will provide a larger image of the moon, but a shorter focal length will provide a wider field of view.
  • Eyepiece: The eyepiece you use will affect the magnification and field of view of the image.

Recommended Telescope Lenses for Lunar Observations

Here are some of the best telescope lenses for lunar observations:

LensMagnificationField of View
25mm Plossl48x1.3 degrees
10mm Plossl120x0.5 degrees
6mm Plossl200x0.3 degrees

These lenses are all affordable and widely available, making them great options for beginners and experienced observers alike. Keep in mind that the best lens for lunar observations will depend on your telescope’s aperture, focal length, and other factors, so be sure to experiment with different lenses to find the one that works best for you.


Choosing the best telescope lens to view the moon can be a daunting task, but it ultimately depends on your personal preferences and budget. If you are looking for an affordable option, a small entry-level telescope with a 60mm aperture at 70x magnification can provide breathtaking views of the moon’s surface.

For those willing to spend more, the Zhumell Z8 telescope with a 203mm aperture and a focal ratio of f/5.9 can offer even better views of the moon and other celestial objects. Additionally, using filters such as the No. 80A and No.12 can enhance lunar observing and reveal more details.

Remember to choose a clear night with minimal light pollution for the best viewing experience. It’s also important to note that the best time to view the moon is a few days after the first quarter, when the moon is perfectly positioned in the night sky and there is enough light to reveal an astonishing amount of detail.

Overall, investing in a high-quality telescope and accessories can provide a rewarding and unforgettable experience of viewing the moon up close and personal.
