Celestron 93230 1.25 inch / 8-24mm Zoom Eyepiece, Black/Silver & 93326 2 x 1.25 Inch Omni Barlow Lens

Celestron 93230 1.25 inch / 8-24mm Zoom Eyepiece, Black/Silver The amazingly versatile Celestron 8 mm - 24 mm Zoom Eyepiece allows you to choose from a variety of magnifications in a flash! Simply grip the rubberized barrel and turn it slowly while looking through the eyepiece, and then pick the best power for the object you are observing. Alternatively, you can use the lowest magnification (24 mm) to find an object and center it in your field of view, and then increase the power until the desired view is achieved. It is fast and easy, and lets you examine any object at various magnifications without requiring you to physically change eyepieces. The Celestron 8 - 24 mm Zoom Eyepiece uses premium optics that are fully multi-coated for crisp, clear images. The folding eyecup lets you view with or without glasses, and the field of view (40 - 60°) works well for terrestrial observations as well as for views of the Moon, planets, and deep-sky objects. Celestron 93326 2 x 1.25 Inch Omni Barlow Lens Celestrons premium quality 31.7mm achromatic Omni Barlow lens (#93326) is compact and lightweight. It is under 75mm long and is Multicoated A Barlow lens is the astronomy accessory that keeps on giving! Insert it between your eyepiece and your telescope to get double the magnification instantly. Let’s say you have two eyepieces in your accessory case, a 10 mm and a 25 mm. Add a Celestron Omni 2X Barlow Lens to the mix, and now you have four magnifications to choose from. Combining this lens with the 25 mm provides double the magnification, or the equivalent of a 12.5 mm eyepiece, while the 10 mm gives you the power of a 5 mm eyepiece. Eye relief is the distance your eye has to be from the first lens in the eyepiece in order to see the full field of view. When you use a Barlow lens with an eyepiece, you get double the magnification, but the eye relief is not affected. This is a good thing, because normally the shorter the focal length of the eyepiece, the less eye relief you have. In other words, a standard 10mm eyepiece, as a general rule, will have better eye relief than a 5mm eyepiece. Bonus! The Celestron Omni 2x Barlow comes in a sleek, silver package. The two-element optics are fully multi-coated, and the edges of the lenses are blackened to cut down on internal reflections. The 1.25” barrel will fit in standard 1.25” focusers and diagonals, and the Barlow will accept 1.25” eyepieces. A metal thumbscrew locks the eyepiece firmly in place.
