Telescopes & Astronomy

A comprehensive and authoritative account tracing the development of the telescope from its earliest origins to the modern era. History of the Telescope by Henry C. King is an essential reference for astronomers, historians of science, and anyone fascinated by how this revolutionary instrument transformed our understanding of the universe.

• Get extra enjoyment out of your Celestron FirstScope Telescope!
• Kit includes a Moon filter and two eyepieces with 24X and 50X magnification
• The 5x24 finderscope makes locating objects much easier
• Take your FirstScope telescope anywhere with the nylon carry bag
• Learn more about the night sky with BONUS Astronomy Software download

• 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.

Unleash the power of your smartphone to take you on a guided tour of the night sky—no telescope experience required. Patented, award-winning StarSense sky recognition technology uses your smartphone to analyze star patterns overhead and calculate the telescope’s position in real-time. 

NOTE: to protect your scope optics from dust in storage we recommend the Pegasus 6-8" Dust cover for the bottom of your scope. (Product Number 126685)
