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.

80mm refractor with fully coated glass optics for bright, sharp views.

Includes 25mm and 10mm eyepieces, 2x Barlow Lens, StarSense smartphone dock, erect image diagonal, 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.

• Connect your Canon mirrorless camera to the 8” RASA with one simple solution—no other adapters required.
• Places the camera sensors at the proper backfocus distance for the 8” RASA for pinpoint stars across the entire field of view.
• Uses the camera’s bayonet mount for a secure connection that won’t rotate once installed.
• Made of machined aluminum with black anodized finish.

• Connect your Sony mirrorless camera to the 8” RASA with one simple solution—no other adapters required.
• Places the camera sensors at the proper backfocus distance for the 8” RASA for pinpoint stars across the entire field of view.
• Uses the camera’s bayonet mount for a secure connection that won’t rotate once installed.
• Made of machined aluminum with black anodized finish.

• 6” (150mm) 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
• 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
• Accessories include a 25mm eyepiece, 1.25” star diagonal and 6x30 finderscope

The 6” Schmidt-Cassegrain optical tube offers 40% more light gathering ability than a 5” telescope. The Schmidt-Cassegrain design also eliminates chromatic aberration, making it a good choice for entry-level astroimaging.

NOTE: The recommended solar filters for this scope for solar observing are;

- the Orion 185 mm (7.17") Glass Solar Filter (Product No. 125081) or

- the Meade Glass White Light Solar Filter 172 - 180 mm (Product No. 125918).

• 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.
• NEW Ultra-Stable Focus System – six precision sealed ball bearings virtually eliminate image shift.
• Integrated air cooling system –12V DC MagLev fan reduces cooldown time and provides optimal air flow while filtering out dust.
• Internal filter mount – seamlessly accommodates a Light Pollution Imaging Filter into the optical path.
• CGE dovetail mounting rail.
• Performs over a wider spectral range than most telescopes, from 390-800 nm, so more of the light passing through the astrograph is in sharp focus.
