Best Telescope Filters of 2025

The Neewer Telescope Filters Set includes a Lunar & Starglow Filter, a CPL Filter, and 5 Color Filters (Red, Orange, Yellow, Green, Blue). The filters are designed to reduce glare and light scattering, increase contrast, enhance definition and resolution, reduce irradiation, and lessen eye fatigue. The standard 1.25" thread size fits most telescopes, and the color filters can be easily screwed into the eyepieces lens. The 5 color filters each have unique benefits, including making Mercury and Venus stand out from the blue sky during the day (Red), increasing contrast between light and dark areas (Orange), bringing out the polar ice caps on Mars (Yellow), enhancing frost patches and polar projections on Mars (Green), and splitting the binary star Antares when at maximum separation (Blue).

The Celestron Telescope Moon Filter is an eyepiece accessory that reduces moon glare and enhances lunar crater details, making it great for full moon observing. It threads onto most 1.25" eyepieces in seconds and is also useful for extra bright planets as well as terrestrial viewing over sand or snow. It is a must-have for any stargazer who wants to get a clearer view of the moon's surface.

The SVBONY Telescope Filter is a 1.25 inch polarizing filter designed for astronomical telescope eyepieces. It reduces the amount of light entering the eyepiece, enhances contrast of lunar detail and allows for maximum contrast of lunar and planetary images. The neutral colored optical glass preserves the moon's natural color and the filter thread is standard. With the ability to adjust light transmission from 1% to 80% by rotating the filter housing, users can achieve optimal performance and finer control of image brightness.

The Celestron Accessory Kit is the perfect all-in-one solution for telescope enthusiasts. With a 2x Barlow lens and 5 Plössl eyepieces featuring a 52-degree field of view, this kit is a great way to enhance your view and instantly boost power. The kit also includes colored filters for astronomical viewing like a moon filter and popular planetary filters. The sturdy, foam-lined case will protect your accessories and even has room to add more eyepieces later.

The SVBONY Telescope Filter Kit includes 7 high-quality filters, including a moon filter, CPL filter, and 5 color filters. The CPL filter eliminates polarization and enhances contrast in photographic images, while the 5 color filters highlight features on Mars, Jupiter, and Saturn. The kit is made with a durable aluminum alloy frame and optical glass, and is compatible with standard 1.25" filter threads, making it suitable for use with most eyepieces and accessories. The moon and skyglow filter reduces glare, enhances surface details, and provides better contrast by filtering out selective wavelengths of low-pressure sodium used in street lighting.

The SVBONY Telescope Filter 1.25 inches UHC Filter is designed to selectively reduce the transmission of certain wavelengths of light, including those produced by artificial light. This filter produces exceptionally sharp and clear images, making it one of the most popular astronomy accessories. It can be used for celestial observations and astrophotography, making the sky background darker, and improving the contrast of emission nebulae. The filter has a 1.25" barrel diameter, is cased in a sturdy transparent case, and has a standard filter thread for 1.25" eyepieces and other accessories. The optical glass lens and aluminum frame significantly reduce light pollution, making it ideal for city and suburban observation.

The SVBONY Telescope Filter is designed to enhance your astrophotography experience by significantly reducing light pollution from both natural and artificial sources. This filter improves the contrast of nebulae against the sky, making them stand out beautifully during your observations. You’ll find it particularly helpful for capturing high-contrast images even in bright city skies or under a full moon. Additionally, the dual-band design simplifies your post-processing efforts, allowing you to focus more on enjoying the beauty of the cosmos without the hassle of extensive editing.

The Astromania Telescope Filter Set includes six filters designed to enhance your lunar and planetary observations. The #23A Light Red filter boosts contrast, making details on planets and the Moon more visible. The #12 Yellow filter is perfect for highlighting Moon craters and Martian features, while the #80A Blue filter improves contrast on faint areas of the Moon, Mars, Jupiter, and Saturn without diminishing brightness. Additionally, the #56 Light Green filter helps you observe the ice caps on Mars and enhances the contrast of structures in Jupiter's atmosphere. Together, these filters offer a more detailed and enjoyable viewing experience.

The SVBONY Telescope Filter 1.25 inches CLS Filter is a durable and scratch-resistant filter that offers stable central wavelengths and precise coatings for high transmission of pass-band and off band. With 90% transmission of main nebula emission lines and 0.1% transmission of off-band, it is effective in suppressing urban light pollution and improving the contrast of shooting target. This filter is suitable for deep sky visual astronomical photography and compatible with color CCD cameras and unmodified DSLR.

This Telescope Eyepiece Filter Set includes 6 different color filters, each with its own function, that can meet your various needs. The threaded filter is compatible with any 1.25 inch telescope and can be used individually or in stacks. These high-quality filters are easy to install and use, helping to filter out unnecessary light and provide a clearer view. Additionally, the set comes with a portable shockproof storage box, making it easy to transport the filters.
