B&H has put together the Celestron NexStar 4 SE 102mm f/13 Maksutov-Cassegrain GoTo Observation Kit to give you everything you'll need to get out and sky watch. It includes a 4" aperture (102mm) NexStar 4 SE Maksutov-Cassegrain telescope with a single-arm motorized fork mount and stainless steel adjustable-height tripod, the SkyPortal WiFi module that directly connects to your Windows or iOS smartphone running the free SkyPortal app, a Power Tank power pack to provide power to the telescope and small electronics in the field, an AC to DC power adapter, a five-piece eyepiece set, six 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.

  • Celestron NexStar 4 SE 102mm f/13 Maksutov-Cassegrain Go-To Telescope

    Celestron's NexStar 4SE 125mm f/13 Maksutov-Cassegrain GoTo Telescope is a powerful, versatile and user-friendly catadioptric-style scope that can be used for observing everything from the Moon and planets to bright deep-sky objects like stars, 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 Crown optical glass elements. Similar to their Schmidt cousins, the Maksutov design exchanges the conventional front corrector plate with a convex meniscus lens which results in a smaller secondary mirror — limiting obstruction and increasing contrast, while eliminating the need for periodic collimation. While the focal ratio is a relatively slow f/13, the scope's optical performance, added to the mount's precision tracking system and integrated equatorial wedge allows it to be a competent astrophotography/imaging platform for the Moon and planets.

    Driving the dual servo motors on the mount is the brains of the NexStar 4SE: the iconic NexStar+ computer hand controller. Packed with 40,000+ celestial objects, it can hold up to 100 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; and the ability to automatically trigger a camera's shutter release for Fastar or piggyback wide-field photography, or conventional prime-focus astrophotography.
