Celestron NexStar 8SE 203mm f/10 Schmidt-Cassegrain GoTo Telescope
Key Features
  • 203mm Schmidt-Cassegrain Telescope
  • 2032mm Focal Length, f/10 Focal Ratio
  • StarBright XLT Optical Coating System
  • Single-Fork Motorized GoTo Alt-Az Mount
Representing the largest aperture in the series and drawing in more light to see deeper into space than smaller versions, Celestron's NexStar 8SE 203mm f/10 Schmidt-Cassegrain GoTo Telescope is a powerful yet portable scope that can be used for observing everything from the Moon and planets to deep-sky objects like stars, galaxies, and nebulae, while maintaining the user-friendly interface of the SE series. 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. While the focal ratio is a relatively slow f/10, the mount's precision tracking system allows it to be a competent shorter-exposure astrophotography imaging platform for the Moon and planets.

Celestron NexStar 8SE Overview

Representing the largest aperture in the series and drawing in more light to see deeper into space than smaller versions, Celestron's NexStar 8SE 203mm f/10 Schmidt-Cassegrain GoTo Telescope is a powerful yet portable scope that can be used for observing everything from the Moon and planets to deep-sky objects like stars, galaxies, and nebulae, while maintaining the user-friendly interface of the SE series. 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. While the focal ratio is a relatively slow f/10, the mount's precision tracking system allows it to be a competent shorter-exposure astrophotography imaging platform for the Moon and planets.

Driving the dual servo motors on the mount is the brain of the NexStar 8SE: The iconic NexStar+ computer hand controller. Packed with 40,000+ celestial objects, it can hold up to 100 additional user-defined destinations and is updatable 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.

Performance
  • 8" (203.2mm) aperture
  • f/10 focal ratio
  • 2032mm focal length
  • Crown optical glass primary mirror
  • StarBright XLT optical coatings: Multi-layer aluminum/SiO2 (quartz)/TiO2 (titanium 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
  • Internal focusing mechanism
  • Resolution: 0.69 arcsec (Rayleigh); 0.57 arcsec (Dawes)
  • Secondary mirror obstruction: 2.5"; 31% by diameter; 9.77% by area
  • Fastar capability: Secondary mirror can be removed and a DSLR or imaging rig mounted in its place for fast wide-field astrophotography
NexStar+ Computer Controller
  • 2-line, 16-character LCD display
  • 19 fiber optic backlit red LED buttons
  • Database of over 40,000 celestial objects plus 100 user defined
  • Automatically slew to planets, stars, constellations, and a variety of catalogs
  • Camera control: For piggyback wide-field or conventional astrophotography through the optical tube assembly, the controller can automatically trigger the shutter release to capture the image
  • 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
  • Constellation Tour: Allows you to take a tour of all the best objects within a particular constellation
  • Alignment procedures: SkyAlign, Auto 2-Star, 1-Star, 2-Star, and Solar System
  • SkyAlign alignment: Takes minutes, with minimal effort or experiencepoint the telescope at three bright objects in the sky, and the telescope does the rest
  • Nine slew speeds: 5°/sec, 3°/sec, 1°/sec, 2x, 4x, 8x, 16x, 32x, and 64x
  • Sidereal, Solar, and Lunar tracking rates for observing the fast-moving Moon, to slower-moving deep-space subjects
  • Tracking modes: Alt-Az, EQ North, EQ South, Off (no tracking when using as a terrestrial spotting scope)
  • RS-232 communication port allows for computer control
  • Flash updatable via the Celestron website
Database Details:
  • Solar system objects including the Sun, Moon, and planets
  • Named objects
  • Stars: Asterims, variable stars, double stars, named stars
  • Caldwell catalog
  • Messier catalog
  • NGC catalog
  • SAO catalog
  • Constellations
