The Best Filter for Mars: Enhance the Way You See Mars!


Nothing beats the feeling of searching the sky for celestial objects. But finding the right equipment can be pretty stressful.

If you’ve ever tried to observe Mars, you know it’s no easy business. It requires a great deal of practice. Not to mention that Mars will only be visible for a limited period of time. As a result, finding all of the necessary equipment is essential. 

One of the important items for viewing Mars is the eyepiece filter you’ll use for your telescope. So you might be wondering what is the best filter for Mars?

There are several brands to choose from. It’s important to choose the one that improves the contrast and details on Mars the most. Otherwise, you’ll get some faint brown and orange tones with no identifiable characteristics.

Choosing one might be really complicated if you are new to this. We’ve compiled a list of the top 5 Mars filters of 1.25 inch barrel. We’ll also teach you what to look for in a filter. 

So, without further ado, let’s get right to it!

Comparison Table

More About the Product

The Neewer 1.25-inch filter set is the first on the list. This filter set is most suited for seeing the moon, although it may also be used to observe Mars. The filters suit the needs of the average user at a decent cost.

The Moon and Skyglow filters are the handiest in the set, in our eyes at least. This filter was created to let in as much light as possible. This reduces Skyglow caused by background glow and artificial lights.

As a result, contrast and surface detail will be improved, while glare will be reduced.

The kit also includes a CPL filter. It is a piece of glass attachment that helps in the minimization of glare generated by reflections. This is a filter that most outdoor photographers use.

As dispersed light from surfaces is decreased, you may experience ideal contrast and enhanced details.

Let’s move on to the five-color filters. The Neewer 1.25-inch set offers red, orange, green, yellow, and blue. As you may be aware, each color filter has a certain purpose. Let’s go over what each filter will provide you.

Red, for example, is used in big telescopes. It sharpens borders and improves contrast for Mars.

The orange filter improves the contrast between bright and dark regions. It also improves the detection of dusty storms on Mars and can see through clouds to some extent.

Yellow filter, on the other hand, improves viewing of Mars by intensifying blue clouds, improving contrast level, and brightening dessert regions. The primary feature is that you may have an enhanced vision of the polar ice caps. 

The blue one brings out detail in Mars’s atmospheric clouds and boosts contrast on the moon.

The green filter shows a greater quality view of ice patches, ground fogs, and polar projections of Mars. This is also used as an all-purpose filter for viewing the Moon.

And that’s all there is to it when it comes to filters! It’s worth noting that the Neewer 1.25 inch isn’t deemed high-end. However, for casual observations, it provides good value for money. 

It’s also useful for someone who is just starting off and wants to experiment with filters. This is why it ranks first on our list.


  • Let’s have tons of light.
  • Reduces a lot of glare.
  • Improves the detail on the surface.
  • Adds in variety with the 5 color filters.


  • Doesn’t darken the whole environment.

They help draw contrast and increase the sharpness of Mars as well as Jupiter, and Saturn. They also allow for the observation and photographing of surface detail that would otherwise be nearly undetectable.

Most observers would use the red and orange one from the set specifically for Mars. The red filter increases contrast. While the orange will detect the polar ice caps better.

The filter set has a protective case preventing dust and moisture from harming the filters. The threads are pretty standard. The framing for this filter is also metal.

One drawback you might face for this product is that they don’t come with instructions for the use of filters. But all in all, this is a pretty good set for the price range.

What Do Deep Sky Filters Do for Mars?

Deep sky filters, also known as light-pollution filters, are used to remove the background glow of street lighting while increasing the detail in faint nebulae.

Deep-sky filters are carefully coated to eliminate reflections to the greatest extent feasible.  It reduces brightness and allows viewing of Mars even in heavily light-polluted areas. they will increase contrast and offer a greater quality of viewing for which they are somewhat expensive.


Question: Why is the view in my telescope blurry for Mars?

Answer: Vision for Mars basically depends on atmospheric conditions. When there is turbulence, your viewing will be blurry.

Question: Can UHC filters help block IR?

Answer: No, UHC filters are not designed to prevent IR or UV light radiation.

Question: What’s the best color filter for viewing polar ice caps on Mars?

Answer: For polar ice caps, try the following color filters: #25 Red, #56 light green, and #58 green.

To Summarize

There are many filters you can try for a relatively low enough price. We hope our list of the 5 best filter for Mars helped you get the one suitable for you. You have all you need now to view Mars with greater vision quality.
