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.

  • 4″ aperture

  • 1325mm focal length
  • BK7 optical glass primary mirror
  • StarBright XLT optical coatings: Multi-layer aluminum/SiO2 (quartz)/TiO2 (titanium dioxide)/Si02 (silicon dioxide) mirror coatings with flat reflectivity across the light spectrum for both astrophotography/astroimaging and visual observation
  • Multi-layer MgF2 (magnesium fluoride) and HfO2 (hafnium dioxide) anti-reflective lens coatings
  • High-transmission water white glass corrector lens with 97.4% light transmission
  • Resolution: Rayleigh: 1.36 arcsec / Dawes: 1.14 arcsec
  • Secondary mirror obstruction: 1.25″, 34.4% by diameter / 11% by area
NexStar Computer Controller
  • Two-line, 16-character LCD display
  • 19 fiber optic backlit red LED buttons
  • Database of over 38,000 celestial objects plus 25 user-defined
  • Automatically slew to planets, objects, constellations plus a variety of catalogs, including the Messier, NGC, Caldwell, and SAO brightest stars
  • Anti-backlash compensation programs-out play between gears for more precise tracking
  • Tour Mode: Shows a selection of the most popular objects for the time and date you are observing
  • Pre-programmed alignment systems including SkyAlign, Auto 2-Star, 1-Star, 2-Star, and Solar System for fast and easy set up
  • SkyAlign alignment: Takes minutes, with minimal effort or experience – Point the telescope at three bright objects in the sky, and the telescope does the rest
  • Pre-set sidereal, solar, and lunar slew speeds for observing the fast-moving Moon, to slower-moving deep space subjects
  • Nine slew speeds: 4°/sec, 2°/sec, 1°/sec, 0.5°/sec, 2x, 4x, 8x,16x, and 32x
