  • SVBONY SV155 1.25 inch 7-Piece Telescope Filter Set

    The SVBONY SV155 7-piece filter set equips your 1.25-inch eyepieces for detailed lunar and planetary observation. This kit includes 7 essential filters—a Moon filter, a Circular Polarizing (CPL) filter, and 5 distinct color filters—all constructed from 2mm thick optical glass. Each filter threads directly into any standard 1.25-inch eyepiece with M28.5*0.6 threads, providing an immediate and noticeable boost in contrast on specific celestial targets.

    A 7-Piece Set for Lunar and Planetary Contrast

    This comprehensive kit is designed as a powerful starter pack for visual observers. The 7 filters provide the tools needed to manage the overwhelming brightness of the Moon and to selectively enhance subtle details on the planets, which are often washed out by atmospheric turbulence or the planet's own brightness. Instead of a single, generic filter, you get a specialized selection to tackle specific observational challenges.

    CPL & Moon Filters: Cutting Glare on Bright Targets

    Observing the Moon without a filter can be uncomfortably bright, causing your pupil to constrict and hiding faint surface features. The included Moon filter acts like a pair of sunglasses for your telescope, reducing overall brightness to reveal subtle rilles, crater walls, and mare textures. The CPL filter goes a step further by specifically blocking polarized light, which dramatically increases contrast not only on the Moon but also on planetary surfaces and atmospheres.

    5 Planetary Color Filters: Isolating Specific Surface Details

    Color filters work by blocking certain wavelengths of light, which makes features of a complementary color stand out more clearly. This is a classic technique for bringing out faint details on planets that are otherwise invisible. The SV155 set includes five of the most useful planetary filters for visual work.

    • #23A Bright Red: Sharpens boundaries of Mars' polar ice caps and enhances surface details.
    • #21 Orange: Increases contrast in Jupiter's cloud belts and helps reveal the Great Red Spot. Also useful for sharpening details on Mars.
    • #12 Yellow: Brings out reddish and orange features on Jupiter and Saturn, and enhances crater details on the Moon.
    • #56 Bright Green: Enhances the view of ice fogs on Mars and improves contrast within Saturn's ring system.
    • #82A Bright Blue: Accentuates atmospheric details, like the cloud belts and zones on Jupiter and Saturn.

    Universal 1.25" Fit with M28.5*0.6 Threads

    Each of the 7 filters in the SV155 set is housed in a durable aluminum alloy cell and features standard M28.5*0.6 threads. This ensures compatibility with virtually any 1.25-inch (31.7mm) telescope eyepiece, filter wheel, or camera nosepiece on the market. The 2mm thick optical glass is ground and polished to maintain the integrity of your optical train, ensuring you see planetary details without added distortion.

  • What is the main purpose of the SVBONY SV155 7-piece filter set?

    The SVBONY SV155 set is designed for visual observers to enhance contrast and detail on the Moon and planets. The Moon and CPL filters reduce glare from bright objects, while the five color filters selectively block parts of the light spectrum to make specific features, like Jupiter's cloud bands or Mars' polar caps, easier to see.

    Which filter from the SV155 set is best for viewing Jupiter's Great Red Spot?

    The #21 Orange filter is the most effective in the SV155 set for enhancing Jupiter's Great Red Spot. It increases the contrast between the reddish spot and the surrounding lighter cloud zones. The #82A Bright Blue filter is also useful for highlighting the boundaries of Jupiter's belts and zones.

    How does the CPL filter in the SV155 set differ from the Moon filter?

    The Moon filter is a neutral density filter; it reduces the brightness of all colors of light equally, acting like sunglasses to make viewing more comfortable. The CPL (Circular Polarizing) filter specifically blocks polarized light, which is often reflected glare. This not only reduces brightness but can also significantly increase surface contrast, making it useful for planets as well as the Moon.

    Will the SVBONY SV155 filters fit my telescope's 1.25" eyepieces?

    Yes. The SVBONY SV155 filters feature standard M28.5*0.6 threads and are designed for a 1.25-inch (31.7mm) barrel. They will screw directly into the base of almost any 1.25-inch eyepiece, regardless of the telescope brand.

    Why are there five different colors in the SV155 filter set?

    Different colors are used to highlight specific features on different planets. A filter works by passing its own color while blocking others, which increases the contrast of features that have a complementary color. For example:

    • A red filter helps see surface features on Mars.
    • A blue filter helps see atmospheric clouds on Jupiter and Saturn.
    • An orange filter helps see details within Jupiter's belts.

    Are the SVBONY SV155 filters made of glass or plastic?

    The SVBONY SV155 filters are made with 2mm thick optical glass lenses set in anodized aluminum alloy frames for durability and clear, distortion-free views.
