Neewer 1.25-inch Telescope Filter Kit: CPL + Moon & Skyglow + Red/Orange/Yellow/Green/Blue Eyepiece Filters

The essentials (and the small catch)

This Neewer 1.25-inch telescope filter kit is aimed at lunar and planetary observers who want a bit more contrast and definition without changing their telescope setup. The kit includes a Moon and Skyglow filter, a CPL filter (for reducing scattered light), and five colour filters (Red, Orange, Yellow, Green and Blue) intended to help different targets stand out.

The small catch, worth noting before you get excited: the telescope itself isn’t included. This is an accessories kit, so you’ll need a telescope/eyepiece arrangement that uses a 1.25-inch filter size.

Key points: why these filters exist

On the face of it, these filters are about controlling the light reaching your eyepiece. In practice, that means less glare and light scattering for brighter objects, and more selective wavelengths for bringing out surface detail or separating features you’d otherwise miss.

It’s also a sensible “try a few approaches” bundle. Instead of betting everything on one filter, you get a mix: a Moon and Skyglow option for general bright-sky/lunar work, a CPL filter that targets reflections from scattered light, plus colour filters that can be rotated depending on the planet (and even the observing conditions).

So, is it a good idea? Over paper, yes—particularly if you observe the Moon and planets and you’ve noticed that haze, glare, or washed-out contrast makes targets harder to judge.

What you’ll notice in use (where it shines)

Moon and Skyglow filter: this is designed to cut down glare and highlight more surface detail, improving contrast. It also “filters out” selective wavelengths associated with low-pressure sodium and other man-made street lighting, which is a common real-world issue if you observe from anywhere near lights.

CPL filter: it’s intended to reduce scattered light by cutting reflections. The end result you’re buying for is the ability to see detail behind glare—especially relevant for the Moon and bright planetary targets where small amounts of stray light can flatten the view.

Colour filters: these are the most “target-specific” part of the kit. The included guidance is fairly clear on what each colour is meant to do, for example: - Red is described as helping Mercury and Venus stand out from a blue sky when observing during the day. - Orange is described as improving contrast between light and dark areas and penetrating clouds. - Yellow is suggested for viewing Mars by bringing out polar ice caps. - Green is aimed at frost patches, surface fogs and polar projections on Mars. - Blue is described as helping split the binary star Antares at maximum separation.

A quick micro-scenario: say you’re observing Mars on a night where the surface looks a bit muted. You might start with a yellow filter to emphasise the polar ice caps, then swap to green if you’re trying to pick out frost/fog-like features. That kind of “swap and compare” is exactly what bundles like this are for.

What matters most when choosing

Before buying, the main thing to verify is fit. This kit is for standard 1.25-inch threaded filters, with a stated 1.25 inches/3.17 cm thread size. The description also says the colour filters include the grooves needed to be softly screwed into eyepiece lenses, which suggests a direct threading method rather than snap-on compatibility.

It also depends on what you want most: - If your priority is reducing glare and improving contrast for lunar/planetary sessions, the Moon and Skyglow plus CPL combination is the backbone. - If you’re specifically experimenting with how different planets present through selective filtration, the colour set is where the fun (and usefulness) comes from.

Bear in mind, though, that filters don’t magically fix everything. If your observing conditions are poor or your optics are the limiting factor, filters may help some, but they won’t replace good viewing conditions.

Tech specs

• Type: Telescope eyepiece filters kit (CPL + Moon and Skyglow + colour filters)
• Thread size / filter size: 1.25 inches (3.17 cm)
• Included filters: 1× Moon and Skyglow Filter, 1× CPL Filter, 5× Colour Filters (Red, Orange, Yellow, Green, Blue)

Pros

• Covers multiple approaches in one pack: glare/scattered light control plus colour-based selective filtration.
• Useful for lunar and planetary observation, with specific target ideas for the colour filters.
• The kit is built around a common 1.25-inch filter thread size, so it should suit many setups on paper.

Limitations (so expectations stay realistic)

• It’s a filter kit only, the telescope and eyepieces are not included.
• It may not suit you if your telescope/eyepiece system doesn’t use the stated 1.25-inch threaded filter size.
• Filters can enhance contrast and definition, but they can’t compensate for major problems like very light-polluted skies, unstable seeing, or an incompatible optical train.

Buying verdict

It’s a solid pick if you observe the Moon and planets and you want a straightforward way to experiment with contrast, glare and selective colour effects—without buying filter after filter individually. The Moon and Skyglow + CPL pairing is particularly relevant for taming glare and reflections, while the five colour filters give you options for different targets (including the kit’s specific notes on Mars and Antares).

You may want to skip it if you’re not using 1.25-inch threaded eyepieces, or if you already have a filtering setup that meets your needs. And if your main issue is something unrelated to contrast/glare (like optics, tracking, or observing conditions), this will only be part of the answer.

Mini FAQ

What’s included in the kit?

You get 1 Moon and Skyglow filter, 1 CPL filter, and 5 colour filters: Red, Orange, Yellow, Green and Blue.

Do I need a 1.25-inch telescope setup?

Yes—this kit is designed around a 1.25-inch threaded filter size, and the description suggests the colour filters screw into the eyepiece lens area.

Does it help with light pollution?

The Moon and Skyglow filter is described as filtering out selective wavelengths used in street lighting, and both it and the CPL filter are positioned for glare/scattered light reduction.

Is it only for the Moon?

No. The kit is clearly aimed at lunar and planetary observation, and the colour filters are described with planet/star-specific intentions.

Should I expect better results immediately?

If you’re currently fighting glare, haze or washed-out contrast, you may notice improvements by swapping filters during a session. If conditions or optics are the bigger bottleneck, results may be more modest.
