Telescopes & Astronomy

Wide dovetail bar to fit CGE or Losmandy style saddles

• 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.

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).

• 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

• 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.

• 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.

• 8" Schmidt-Cassegrain optical tube assembly (OTA)
• Features Celestron's premium patented StarBright XLT optical coatings
• 2032 mm focal length (f/10)
• Fastar compatible
• Tube constructed of durable and lightweight aluminum
• Includes: 25mm eyepiece (81x), 6x30 optical finderscope, star diagonal, 1.25” visual back, CGEM style dovetail bar

NOTE: The recommended solar filter for this scope for solar observing is the Astrozap Glass Solar Filter (Product No. 124451) 

The Celestron X-Cel LX 2.3mm eyepiece delivers high-magnification views ideal for planetary and lunar observation, featuring a fully multi-coated six-element lens design and a generous 60° apparent field of view. With 16mm of comfortable eye relief, pop-up rubber eyeguards, and a threaded 1.25" barrel that accepts standard filters, it's a premium choice for detailed, high-contrast viewing.

• X-Cel LX eyepieces, optimized for planetary viewing, offer a 60° field of view through a six-element fully multi-coated lens system
• Pop-up rubber eyeguards provide comfort and increase contrast.  Raise and lower with a simple twist.
• A treaded rubber grip offers a no-slip grip, even with gloves on
• 1.25” barrels are threaded to accept filters

The Celestron Dew Heater Ring is the ideal dew prevention solution for your Celestron telescope.

The Dew Heater Ring permanently mounts to your 5" Celestron Schmidt-Cassegrain optical tube, replacing your retaining ring, so you'll never be caught without it.

The installation process is quick and easy (follow the manual for instructions).
