Telescopes & Astronomy

Unleash the power of your smartphone to take you on a guided tour of the night sky—no telescope experience required.

Patent-pending StarSense sky recognition technology uses your smartphone to analyze star patterns overhead and calculate its position in real time. Check phone compatibility here.

StarSense Explorer app automatically generates a list of objects currently visible. View planets, brighter nebulae and galaxies, star clusters, and double stars from the city. Or take your telescope to darker skies to view faint, deep sky objects.

Manual altazimuth mount with smooth, dual-axis slow-motion controls makes it easy to follow the on-screen arrows to your desired target. When the bullseye turns green, it’s ready to view in the telescope’s eyepiece.

127mm (5”) Newtonian reflector with highly reflective coatings and enough light gathering ability to view all the best celestial objects.

Includes 25mm and 10mm eyepieces, 2x Barlow Lens, StarSense smartphone dock, a red dot finderscope (in case you want to use the telescope without your phone), and a full-height tripod.

NOTE: The Starsense telscope uses your smartphone as a navigation device only, not to take photos.

• 5” (125 mm) f/10 Schmidt-Cassegrain includes StarBright XLT coatings for better light transmission
• The most compact and portable of Celestron’s German equatorial mounts offers the same rigidity as our larger mounts with minimal flexure and an improved industrial design
• Holds a maximum instrument capacity of 30 lb
• Every feature an astroimager wants: PEC, an autoguider port, the ability to image across the meridian, and more
• NEW dual saddle plate is compatible with narrow CG-5 dovetails and wider CGE dovetail. Also compatible with Vixen format dovetails longer than 100mm, but not compatible with Losmandy D format plates.
• Latitude range allows the mount to perform between 7° and 77° latitude

• 11" Schmidt-Cassegrain Optical Tube Assembly (OTA)
• Features Celestron's premium patented StarBright XLT optical coatings
• 2800mm focal length (f/10)
• Fastar compatible
• Tube constructed of durable and lightweight aluminum
• Includes: 40mm eyepiece (70x), 9x50 optical finderscope, star diagonal, 1.25” visual back, CGEM-style dovetail bar

NOTE: For solar observing the recommended solar filter is the Astrozap Glass solar filter 308-314 mm (Product Number 124447). This solar filter is a perfect fit for this OTA.

• Features Celestron's premium patented StarBright XLT optical coatings
• 3910mm focal length (f/11)
• Fastar compatible
• Tube constructed of durable and lightweight aluminum
• Includes: 40mm eyepiece (98x), 9x50 optical finderscope, 2” star diagonal, 2” visual back, CGEM-style dovetail bar

• Fast, wide-field 11” f/2.2 optical design with rare-earth glass for images free of false color, coma, and field curvature
• Large 43.3mm optimized image circle maintains pinpoint stars to the far corners of even the largest astroimaging sensors, while the usable field extends even further to 52mm for larger format sensors
• New Ultra-Stable Focus System (USFS) minimizes focus shift and mirror flop
• Integrated air-cooling system features a quiet, high-output 12V MagLev fan and vents with mesh filters to prevent dust ingress
• Common camera adapters (T-thread and M48) included for easy attachment to popular CCD and DSLR cameras

• Take beautiful images of deep-sky objects from light-polluted suburban locations with the Rowe-Ackermann Schmidt Astrograph 11 (RASA 11) using this light pollution suppression filter
• Custom designed to replace the RASA’s optical window, so you still get optimum optical performance even with the addition of the filter
• Selectively blocks unwanted light pollution while providing over 90% transmission at critical wavelengths
• Maintains a more neutral color balance than other light pollution imaging filters, perfect for imaging colorful nebulae and galaxies
• Every filter is individually tested for light transmission. A graph of test results for your specific filter is included for your reference

• The Celestron Universal T-Adapter connects a DSLR or SLR camera to a refractor for prime focus photography
• The adapter’s chrome barrel slides into any focuser that accepts 1.25” accessories
• T-Threads accept camera brand specific T-Ring (sold separately)

• Store your entire telescope kit—optical tube, mount, and tripod—in one protected, portable, grab-and-go case.
• Ultra-durable 900 denier outer and super smooth inner polyester layers, sandwich 16mm thick EPE foam sheets to create a protective barrier for your telescope, tripod and mount.
