Features

• 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

When you are finished using the telescope, please make sure that all of the pieces are placed back inside the tech kit. If any piece is missing or damaged, please contact LOANERKITS@GEORGIALIBRARIES.ORG. Thank you for your cooperation.
