Celestron 1.25" Observer’s Accessory Kit (#94308)
If you’re just starting out with a telescope or looking to upgrade your basic accessories, the Celestron Observer’s Accessory Kit delivers an instant performance boost. Thoughtfully assembled for the amateur astronomer, this kit includes two versatile Plössl eyepieces, a 2x Barlow lens, three useful filters, a microfiber cleaning cloth, and a sturdy hard case to keep everything safe and organized. Each component has been selected to enhance your views of the Moon, planets, and bright deep-sky targets—making this kit a smart investment for any 1.25” telescope user.
Inside the foam-lined case, you’ll find a 17mm Plössl eyepiece, ideal for medium magnification on most scopes. It’s a great general-purpose eyepiece, whether you’re scanning lunar terrain, watching Jupiter’s moons dance, or taking in the bright core of M13. For higher magnification work, the included 6mm Plössl brings the Moon and planets into sharper focus—particularly useful when atmospheric conditions are steady. Both eyepieces feature a four-element optical design with a 52° apparent field of view, fully multi-coated for enhanced light transmission and clarity.
To double your viewing options, the kit includes a 2x Barlow lens that effectively turns the 17mm into an 8.5mm and the 6mm into a powerful 3mm eyepiece. This Barlow is threaded for T-rings as well, allowing it to serve as a basic T-adapter for prime-focus photography. Just add the correct T-ring for your camera, and you're ready to try your hand at lunar or planetary imaging. The Barlow's internal optics are designed to preserve image sharpness and contrast across the field.
For planetary observers, three threaded filters offer targeted performance boosts. The #80A blue filter is especially helpful for enhancing contrast in Jupiter’s cloud bands or Saturn’s polar regions. The #25 red filter is excellent for Mars, allowing you to tease out detail in the polar ice caps or low-contrast surface features. On brighter targets like Jupiter, it can also bring out deeper atmospheric structure—though it does dim the image, so it's best reserved for larger aperture scopes. The Moon filter—perhaps the most immediately useful in the kit—reduces glare from the full or gibbous Moon, letting you pick out fine crater detail without discomfort. It can also be used on Venus to better observe the planet’s phases.
To keep your optics clean, a microfiber cleaning cloth is included for gentle and residue-free wipe-downs. Just be sure to remove any loose dust with a blower or soft brush first to avoid scratching your lenses. The entire kit stores securely in a foam-padded plastic case that’s roomy enough to hold your accessories and a few extras you might pick up along the way. Each slot is cut to fit its item precisely, helping keep your gear protected in storage or transit.
Whether you're building your first accessory collection or looking to standardize your tools with quality, matched optics, the Celestron Observer’s Accessory Kit offers a practical and affordable upgrade for any 1.25" telescope system.
Why We Like It
This kit provides a solid, well-rounded selection of accessories that will immediately improve your viewing experience—without unnecessary fluff. The eyepieces are sharp and contrasty, the Barlow is optically solid and photo-capable, and the filters are actually useful. You’re not just filling space in your case—you’re adding real value to your observing sessions.
Observing Tip
Don’t assume more magnification always means a better view. On many nights, the 17mm eyepiece (or its 8.5mm equivalent using the Barlow) will give sharper results than the 6mm. Let the atmosphere decide how much power you can use—and enjoy experimenting to find your telescope’s “sweet spot.”
Final Thoughts
The Celestron Observer’s Accessory Kit isn’t just a starter set—it’s a thoughtful upgrade that rounds out your observing toolbox with dependable, well-built optics. If you’re using a 1.25" focuser and want to get more out of every night under the stars, this kit is a smart and practical next step.
