    Orion tele-extenders permit high-magnification "eyepiece projection" photography of the Moon and planets with a Schmidt-Cassegrain telescope. Orion tele-extenders are designed to fit all Celestron and Meade Schmidt-Cassegrain telescopes. Made of anodized aluminum, the tele-extender fits over a 1.25" telescope eyepiece, with one end threading onto the eyepiece holder (visual back) of the telescope, and the other end threading into the T-ring (sold separately) attached to your DSLR camera body. This Standard Tele-Extender is a fixed-length cylinder that provides a single projection magnification depending on the focal length of the eyepiece you use. Some 1.25" telescope eyepieces have housings that are too wide to fit inside the tele-extender.
    A T-ring converts a SLR or DSLR camera mount to a standard T-thread. All camera adapters and universal camera adapters will fit this T-thread. This wide (48mm) T-ring supports full 35mm format cameras. A wide format T-ring is needed for astrophotographic applications using a Nikon DSLR or SLR camera and a focal-reducer / corrector lens.
    This Orion telescope eyepiece adapter lets you use an eyepiece with a barrel diameter that is different from that of your telescope's focuser or star diagonal. Thumbscrew holds the eyepiece securely. Made of anodized aluminum. Use 1.25" telescope eyepieces in a .965" focuser or diagonal.
    This Orion Eyepiece Adapter lets you use a telescope eyepiece of a different size from your telescope's focuser or star diagonal. Internal compression ring holds 1.25" telescope eyepieces securely, without scratching. Black-anodized aluminum. Use 1.25" eyepieces in a 2" focuser or diagonal.
    This versatile filter acts like a dimmer switch for your telescope, toning down the brightness of the Moon or planets to a level that is comfortable. The reduction in brightness and glare unmasks detail in your viewing subject and greatly improves contrast. The filter consists of two high-grade glass polarizing filters in a rotating cell that allows you to adjust the amount of light transmission from 1% to 40%. Such control is highly desirable for lunar observing because the Moon's brightness varies with its phase. The filter is great for terrestrial observing too, especially on sunny days. The filter has an anodized aluminum cell, which threads into the barrel of any standard 2" eyepiece. Storage case included.
    The RS-232 Cable for Celestron Computerized Telescopes connects the GoTo Hand Controller to a PC to use astronomy software to control your telescope.

In seconds, the IntelliScope's two high-resolution digital encoders pinpoint the object, placing it right in the telescope's field of view. The internal database includes 837 stars (including double and variable stars), 7,840 NGC objects, 5,386 IC objects, 101 Messier objects, 8 planets, and 99 user-entered objects. It also features 12 monthly tours of the coolest objects. Whether you are an entry-level or expert astronomer, the Object Locator makes observing the night sky with your IntelliScope Dob incredibly easy and fun.
    Enjoy a wide-field window into the heavens served up by Stratus eyepieces. With an apparent field of 68-degrees -- which translates to a 71% greater viewing area than that of a typical Plossl -- Stratus eyepieces quite literally put more stars in your eyes. In the same way you feel more a part of the action watching a big-screen TV, with Stratus you will feel like you are really experiencing your celestial targets, rather than just viewing them from afar. Each ocular features a monster 1-1/4"-diameter eye lens to look into. Each also has a generous 20mm of eye relief, so you'll get the big picture even if you wear eyeglasses. The optics are fully multi-coated to maximize light transmission to your eyes, and the lens edges are blackened to ensure excellent contrast. Stratus eyepieces fit in both 1.25" and 2" focusers. Each is threaded for filters and comes with protective lens caps.
    Go to a star party and sidle up to any guy or gal who's got a serious telescope. Take a peek in their accessory case and you're almost certain to spot one or more Panoptics.
