Telescopes & Astronomy

• Explore the Universe and control your NexStar Evolution telescope with the free Celestron SkyPortal Powered by SkySafari™ app app for iOS and Android!
• Portable 9.25-inch Schmidt-Cassegrain optical tube with StarBright XLT optical coatings and Fastar compatibility
• Computerized GoTo mount with high-performance worm gears and motors for improved tracking accuracy, along with reduced gear backlash
• Rechargeable lithium-iron phosphate battery with enough power for 10 hours of continuous observing
• Improved industrial design with manual clutches and integrated carry handles, plus the added convenience of two accessory trays and a USB charge port for your smart device

• Flat-field free of optical aberrations like field curvature, coma, astigmatism and chromatic aberration across an entire APS-C sensor.
• Unlike the larger RASAs that work with DSLR and large CCD cameras, the 8” model was designed with color astronomical CMOS cameras, smaller CCD cameras, and mirrorless cameras in mind. The telescope does not work with standard DSLR cameras.
• Ultra-Stable Focus System – precision linear ball bearing virtually eliminates image shift.
• Internal filter mount – seamlessly accommodates a Light Pollution Imaging Filter into the optical path.
• Performs over a wider spectral range than most telescopes, from 400-800 nm, so more of the light passing through the astrograph is in sharp focus.
• The CGX, with its 55 lb load capacity, is Celestron’s most innovative, state-of-the art, computerized equatorial mount to date, and provides a very sturdy and rigid platform for the fully-loaded RASA 8.
• The drive system utilizes low cog DC Servo motors with integrated optical encoders, belt and pulley motor connection, spring-loaded steel worm gears supported by precision sealed bearings, and brass worm wheels for smooth, accurate slewing and tracking performance with little backlash.
• Fully remote imaging capable, with optical limit switches, home sensors, through-mount cabling, and hard stops.
• Included Celestron PWI software allows direct computer control via USB 2.0 connection.
• Proven NexStar+ computerized telescope control technology supports functions to address imagers’ needs, such as All-Star Polar Alignment, Permanent Periodic Error Correction (PPEC), and adjustable tracking through meridian.

• 15mm parfocal Ultra Flat Field eyepiece designed for 1.25” focusers
• Incredibly crisp views from center to edge of field
• Fully multi-coated, 8-element lens design for excellent light transmission
• Wide 65° apparent field of view allows you to see more of the night sky
• Generous 16mm eye relief and fold-down rubber eyeguard for comfortable viewing with or without eyeglasses
• Molded rubber grip ring for non-slip handling

• Ultra-long 56mm focal length provides low power views in telescopes with a long focal length, perfect for viewing wide-field deep sky objects or daytime terrestrial vistas
• 4-element Plössl design provides sharp views to the edge of the 47° apparent field of view
• Fully multi-coated for best light transmission through the lenses, resulting in brighter images
• Comfortable eye relief (52mm) and fold-down rubber eyeguard for comfortable viewing with or without eyeglasses
• Knurled rubber grip ring for non-slip handling during observing sessions
• Threaded to accept most 2” filters

Add the Celestron Stereo Binocular Viewer to your repertoire and enjoy celestial views with more contrast and improved detail!

Our eyes work as a team, and our brains are wired to work with images that both eyes produce together. When we use just one eye to do observations through an optical device, the results are lacking somewhat in detail and contrast. A binoviewer uses two matching eyepieces to allow you to get the most out of your observations. Your eyes will relax, and you’ll find that you can observe for longer periods of time without suffering from eye fatigue.

• Large 80 mm objective lenses for excellent light gathering in low light conditions or for astronomical observing
• Detachable RSR rail for attaching an optional red dot finderscope
• Rubber armored for improved ergonomics and protection from every day use in the field
• Waterproof and nitrogen purged for use in all weather conditions
