B&H has put together the Celestron NexStar 4 SE Observation Kit to give you everything you'll need to get out and sky watch. It includes a 4" NexStar 4 SE catadioptric telescope with a stainless steel adjustable-height tripod, a Power Tank power pack, an AC to DC power adapter, a 5-piece 1.25" eyepiece set, 6 planetary filters, a Moon filter, a 2x Barlow lens, and a foam-lined hard carrying case for the eyepieces and filters. No matter where you are, or what you want to observe, this kit has you covered.

The NexStar 4 SE is an ideal telescope for observing the Moon and planets, bright deep sky objects, or terrestrial subjects. With a weight of just 21 lb including the tripod, the ultra-portable 4 SE features a precision optical system with a 1,325 mm focal length and f/13 focal ratio, and proprietary StarBright XLT multicoatings. Its motorized single-fork mount is controlled via the NexStar hand controller. With alignment aids, guided tours, and a database of over 40,000 objects, this Go-To enabled mount takes the guess-work out of astronomy and gets you viewing faster with quick set-up times and accurate tracking.

The Power Tank is a 12VDC power pack for getting you where you need to go and to run and charge your telescope and accessories when you're off the grid. It features two 12VDC accessory plugs and two USB ports for your electronics, and to get you safely to your observation site, it has an 800,000 candlepower spotlight. A low-power red light helps you set up without affecting your night-adjusted vision. If you're viewing closer to civilization and have access to an outlet, use the AC to DC adapter.

For your observation needs, there are five 1.25"-barrel diameter eyepieces that will produce 41x, 78x, 102x, 165x, and 221x magnifications. A 2x Barlow lens effectively doubles the magnification of each eyepiece for even more viewing versatility. Six planetary filters provide a wide array of light filtering ability for specific color wavelengths, while the neutral density Moon filter makes lunar viewing more comfortable with increased color and contrast. To store and carry your eyepieces and filters, a foam-lined hard carrying case is also included.

  • Celestron NexStar 4 SE 102mm f/13 Maksutov-Cassegrain Go-To Telescope
    Celestron's NexStar 4 SE 102mm f/13 Maksutov-Cassegrain Go-To Telescope is a powerful, versatile and user-friendly Maksutov-Cassegrain style telescope that can be used for observing everything from the Moon and planets to deep sky objects like galaxies and nebulae. Using Celestron's proprietary StarBright XLT multi-coating system, light transmission is increased throughout the entire optical path with anti-reflection multi-coated lenses, highly reflective multi-coated mirrors, and BK7 optical glass.

    The scope's Maksutov variation of the Cassegrain optical system exchanges the front corrector plate of the more common Schmidt design with a convex meniscus lens which not only eliminates the need for periodic collimation, but the nature of the lens requires a smaller secondary mirror which limits obstruction and increases contrast. This optical system, coupled with its precision tracking, allows it to be a competent astrophotography/astroimaging platform for the Moon and planets - despite its relatively slow f/13 focal ratio

    Driving the dual servo motors on the mount is the brains of the NexStar 4SE: the iconic NexStar computer hand controller. Packed with almost 40,000 celestial objects, it can hold up to 25 additional user-defined destinations and is updateable via the Celestron website. It has multiple alignment procedures to get you observing fast - including the super-easy SkyAlign system. Capable of being used in the northern or southern hemispheres, the NexStar has sidereal, lunar and solar tracking speeds to accurately follow near and deep-sky objects, plus nine slew speeds.
