With bare eyes, it will feel like staring directly into a bright floodlight. All of that can be changed with this filter. The high light intensity will be distributed into a dimmer, easier-to-view landscape because of its 1.25 inches of glass.

By reducing glare it will maintain the definition of the moon’s surface. It will not seem so dark that details are blurred. You won’t be disappointed at the expense of a really low price. 

Also, the glass is scratch-free, so it’s a plus point if you’re a sloppy astronomy enthusiast

This filter is just what you are looking for when it comes to seeing the moon in comfort. You can modify the contrast and brightness for a better moon visual experience. 

Here, the moon appears greenish when using the standard moon filter but this filter doesn’t. 

Because the filter is threaded on both sides, it can be stacked with other filters. This suits any 1.25 inches Celestron eyepiece you have.

This filter allows you to gaze at the moon comfortably for hours and see greater detail. Your eyes will appreciate it. You can see the stars, the moon, the venus more clearly with this filter but it won’t roast your eyes.

Orion 05662 1.25-Inch Moon Filter 

Product Overview

The second best moon watching filter we’re going to suggest you is this Orion filter. Interested to know why you should buy this? Well it surely makes a difference! 

The Orion 1.25 inch delivers 13 percent of the beam. With the Moon Filter, you can see more lunar detail and surface details using your telescope. You can see the landscape with more clarity than before only with your telescope

Your telescopic eyepiece’s 1.25-inch barrel threads straight into the metal filter cell.

Especially beneficial for wide-angle telescopes, where the Moon’s glare can be very overbearing. So if you own a telescope with a big aperture, get the filter right away to save your eyes. 

Only 13% of the incoming light passes through the telescope eyepiece filter, increasing contrast and the capacity to spot detail on the Moon. The thread will perfectly fit your eyepieces without any hassle. 

The inherent color of the Moon will not be affected by a perfectly neutral color. Sometimes the filter changes the moon’s color to a greenish hue, it won’t happen with this filter. 



  • You might find it a bit pricey 
  • It’s great for full phases but a little dark for early and late phases. 


Neewer 1.25 inches Telescope Moon Filter

Product Overview

The one we’re going to review right now is an all-time favorite. We call this the best package for all. If you’re looking for a filter for all kinds of planetary observations, not just the moon, you should absolutely go for it. It won’t disappoint you! 

So what does the kit include? Well, it includes “CPL Filter, 5 Color Filters (Red, Orange, Yellow, Green, Blue), Moon and Skyglow Filter, Moon and Skyglow Filter”. 

Also, this is a multipurpose kit. It’ll reduce brightness and light dispersion and increase the contrast by specific filtration. Furthermore, it improves definition and resolution, minimizes irradiation, and reduces visual fatigue.

Let’s talk about the filter for the moon. You’ll be amazed to know that it reduces glare, reveals more surface detail, and improves contrast. It’s a multi-band pass filter that lets a lot of light through in the visible range. 

Here, it selects wavelengths of low-pressure sodium, and other man-made sources commonly utilized in street lighting are effectively filtered out. So there’s no noise for light in your moon-watching sessions. 

Now, what does a CPL filter do? You may cut through the reflections and view the detail behind them by using a CPL filter. Well, this blocks out dispersed light. In photographic shots, it improves the contrast of the moon and planets.

Thread size is 1.25 inches/ 3.17 centimeters, which suits most telescopes. So, most probably it’s compatible with your telescope as well. 

The color filters include grooves that allow them to be readily inserted into the eyepiece’s lens. When observed throughout the day, red assists Mercury and Venus standing out from the blue sky. 

The orange filter improves the contrast between light and dark regions and penetrates clouds. 

Yellow enhances views of Mars by highlighting the polar ice caps. Green on Mars, improves ice patches, surface mist, and arctic projections. When the binary star Antares is at its most separated, blue aids in splitting it.  


  • It’s a complete package for proper planetary visuals 
  • The thread size is compatible with most telescopes 
  • It serves all kinds of visual purposes 
  • For the moon, there are two kinds of filters


  • It’s a great package for newbies but not so advanced for professionals

Buying Guide

We reviewed 5 types of moon filters and these are the best 5 among all. Which one will you choose? Do you know what qualities you are looking for in your moon filter? Let’s find out now before you buy a moon filter that wouldn’t suit your telescope or your eye retinas. 

Let’s walk you through a guide, so you know what qualities you’re looking for before you end up buying a moon filter- 

Good Quality Filter 

First of all, the very quality you’re looking for is a filter that reduces the brightness. You do not want to look at the moon only with the telescope. Because it might look light a big flashlight to you, and you won’t be able to figure out the details from there. 

But a great filter will help you see all the mountains and valleys on the moon. It will cut down the brightness and increase the clarity on the surface of the moon. 


The filter cannot have any hue to it. Normal moon filters have a tendency to make the moon look a bit greenish. When you look through the filter to observe the moon, the moon shouldn’t have any other color to it. 


For someone who’s a bit sloppy, which is fine by the way, do find a filter that is of very good quality. It shouldn’t scratch easily. 

Thread and Size

The threads need to go smooth inside the eyepiece. The thread sizes need to be of the same size. The filters need to suit the telescope as well.


Question: Can UHC filters be used to see the moon?

Answer: UHC filters allow more details and clarity through the lenses. Which means that you can clearly see at a distance. While these filters allow watching planets, getting a moon filter is the best option for looking at the moon. 

Question: Do you need to maintain a specific budget?

Answer: Yes! A budget can be made as you’ll purchase the filter based on that budget. In fact, a specific budget should be made with almost everything in life. 

The Verdict
