  • Celestron AstroMaster Accessory Kit - 1.25"

    Expand the capabilities of your telescope with the 7-piece Celestron AstroMaster Accessory Kit - 1.25". This kit provides four distinct magnifications with its 15mm Kellner and 6mm Plössl eyepieces, plus a 2X Barlow lens that doubles the power of any 1.25" eyepiece. It also includes three specialized filters—a #80A Blue, #25 Red, and a Moon filter—to enhance contrast on planetary and lunar surfaces, all protected in a foam-lined hard case.

    Magnification Optics: 4 Magnification Options from 2 Eyepieces and a 2X Barlow

    This kit provides a versatile range of magnifications for any telescope with a 1.25” focuser. The 15mm Kellner eyepiece delivers a moderate power, ideal for locating objects and viewing star clusters, while the 6mm Plössl eyepiece offers high magnification for resolving detail on the Moon and planets. The included 2X Barlow lens doubles the power of any 1.25" eyepiece, effectively turning the 15mm into a 7.5mm and the 6mm into a powerful 3mm equivalent, giving you four magnification choices right out of the box.

    • Fully Coated Optics: Both eyepieces are fully coated to increase light transmission and deliver brighter, clearer images.
    • DSLR Ready: The Barlow lens features built-in T-threads, allowing you to attach a DSLR camera for basic astrophotography with an optional T-ring.

    Planetary & Lunar Filters: 3 Filters for High-Contrast Views

    Unlock hidden details on celestial objects using the three included 1.25" filters. These filters thread directly onto the eyepiece barrel, reducing glare and enhancing specific surface features that are otherwise difficult to see. Experimenting with filters is a key step in moving beyond basic observation into more detailed planetary and lunar study.

    • #80A Blue Filter: Increases the contrast of Jupiter's cloud belts and highlights the polar ice caps on Saturn.
    • #25 Red Filter: Helps define the polar ice caps on Mars and can be used to enhance cloud structures on Jupiter, though it is best suited for larger aperture telescopes due to its light reduction.
    • Moon Filter: An essential accessory that reduces the overwhelming glare of the Moon, allowing you to observe craters, maria, and rilles in much greater comfort and detail. It's also effective for viewing the phases of Venus.

    Kit Components: Protective Case & Maintenance for Your 7 Accessories

    The AstroMaster Accessory Kit is designed for convenience and longevity. All 7 accessories are housed in a durable plastic carrying case with precision die-cut foam, ensuring each component is protected from dust, moisture, and impacts during transport and storage. A microfiber cleaning cloth is also included to safely remove smudges and dust from your optics without leaving residue, preserving the integrity of your views.

  • What celestial objects can I see with the AstroMaster Accessory Kit?

    This kit is ideal for the Moon and planets. Use the 15mm eyepiece for wide views of the Moon, then switch to the 6mm and the 2X Barlow for high-power views of lunar craters, Jupiter's cloud bands and moons, Saturn's rings, and the polar ice caps on Mars. The filters are specifically chosen to enhance details on these objects.

    How will the #80A Blue filter in the AstroMaster Kit improve my view of Jupiter with my 90mm refractor?

    With a 90mm refractor, the #80A Blue filter will help make the contrast between Jupiter's bright zones and darker belts more distinct. It enhances the visibility of the Great Red Spot and can also bring out more detail in Saturn's polar regions and polar ice caps.

    Is the AstroMaster Accessory Kit compatible with telescopes from other brands?

    Yes. The kit is fully compatible with any telescope that uses a 1.25" focuser and eyepieces, which is the industry standard for most consumer telescopes. You can use these eyepieces, filters, and the Barlow lens on telescopes from Meade, Orion, Sky-Watcher, and others.

    How do I attach my DSLR camera using the 2X Barlow lens?

    The Barlow lens has T-threads machined into its body. To attach your camera, you will need a T-Ring that is specific to your camera's brand and model (e.g., a Canon EOS T-Ring or a Nikon T-Ring). You simply screw the T-Ring onto the Barlow's T-threads, and then attach your camera body to the T-Ring.

    What is the difference between the 15mm Kellner and 6mm Plössl eyepieces?

    The 15mm Kellner provides lower magnification and a wider field of view, making it a great "finding" eyepiece for locating objects and observing larger targets like open star clusters. The 6mm Plössl offers much higher magnification, which is necessary for seeing fine details on bright objects like planets and the Moon's surface.

    Why do I need a Moon filter with the AstroMaster Accessory Kit?

    The Moon, especially when full, is extremely bright through a telescope. This intense glare washes out surface detail and can be uncomfortable to view. The Moon filter acts like sunglasses for your telescope, dimming the view to a comfortable level, which dramatically increases contrast and allows you to easily see features like craters, mountains, and rays.
