Description and specs

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 experience—point 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

Mount & Tripod

Mount:

  • Single-fork alt-az
  • Dual-axis servo motors allow for precise tracking with virtually no vibration
  • Motor resolution: 0.26 arcsec
  • Optical encoders track mount movement to improve tracking and GoTo accuracy while allowing the mount to maintain alignment when moved manually
  • Communication ports: Autoguider port, Aux port, hand controller
  • Runs on eight user-supplied AA batteries or optional 12 VDC power supply

Tripod:

  • Stainless steel legs
  • Adjustable height accommodates a variety of observation positions or users
  • Tray holds accessories such as eyepieces and filters and adds stability and vibration reduction
  • Weight: 10 pounds

Included Accessories

Eyepiece:

  • 1.25"-diameter barrel
  • 25mm focal length produces 81x magnification
  • Anti-reflection multi-coated glass improves color rendition and contrast
  • Threaded barrel accepts most 1.25" astronomical filters
  • Fold-down rubber eyecup for use with or without eyeglasses
  • 33' field of view at 1000 yards

Diagonal:

  • 1.25" input and output accepts most 1.25" astronomical eyepieces and accessories
  • 90° angle puts head in a comfortable position when observing at or near the zenith
  • Corrects view horizontally, but not vertically

StarPointer Finder:

  • Projects a single red dot in line of sight
  • Unmagnified view ensures a wide field of view to make finding objects faster and star-hopping navigation easier
