Experience the gold-standard in astrophotography with the Celestron CGX-L 1100 RASA Computerised Telescope.

The ultra-fast, ultra-wide Celestron CGX-L 1100 RASA Computerised Telescope is the perfect companion for serious astrophotography. Coupled with the unbelievably sturdy CGX-L mount, this all-inclusive setup is the perfect, high-quality start to astrophotography you need.

 

Constructed with 4-element rare-earth glass.

The RASA 1100 utilises a Rowe-Ackermann Schmidt Astrograph optical design with 4-element rare-earth glass. As a result, images through a RASA are top-tier, free of false colour and aberrations such as coma or field curvature. The optical design ensures a remarkably small spot size and minimal vignetting - a result that is unprecedented for an astrograph in this price range.

With a focal ratio of f/2.2 and a focal length of just 620mm, the RASA 11 V2 is incredibly fast, offering wide-field images with a large 43.3mm optimised image circle. Expect edge-to-edge clarity, even with the largest astroimaging sensors with diagonals of up to 52mm wide. This combination ensures the RASA is an optical instrument capable of creating astonishing mosaics of the night sky for astrophotography, for surveying and even for comet hunting.

 

For advanced astrophotography.

The 11-inch RASA V2 OTA of the CGX-L 1100 Computerised Telescope is a dedicated astrograph, with a number of advanced features for astrophotography. The V2 features the new Ultra-Stable Focus System (USFS), named appropriately for the precision linear ball bearing at the heart of the system. During focusing, USFS minimises unwanted lateral motion of the primary mirror (focus shift). When the telescope is pointed at different positions in the sky, the USFS bearing limits movement of the primary mirror (mirror flop). The RASA 1100 V2 OTA is also compatible with the Celestron Focus Motor for electronic focusing (no retrofit kit needed).

The 1100 RASA V2 also features a 12V DC MagLev fan to provide optimal airflow and reduce cooldown time. The OTA is dust-filtered with vents and mesh filters to prevent dust ingress.

Every component of the 11 Rowe-Ackermann V2 OTA is hand-picked by Celestron for optimal performance with both DSLRs and astronomical CCD cameras. From the thickness of the glass or the Dovetail CGE bars on the OTA, the 1100 RASA Optical Tube Assembly is the epitome of optical excellence.

 

With the incredibly rigid CGX-L Computerised Equatorial Mount.

With the CGX-L 1100 RASA Computerised Telescope, you're not only purchasing high-quality optics - you're also getting a high-quality mount. With a payload capacity of over 34kg, the CGX-L EQ Mount is remarkably sturdy. Since the 1100 RASA V2 OTA weighs just 19.5 kg, this gives you almost 15kg of additional payload to work with for the rest of your imaging train. With the CGX-L, experience exceptionally accurate tracking under heavy load in a form factor that remains relatively compact and doesn't break the bank.

But there's more to the CGX-L Mount than just its high payload capacity. Experience some of the best mechanical features and technological advancements in the industry with the CGX-L, such as:

- Smooth & Accurate Operation Under Heavy Load with Larger 144mm Diameter Spring-Loaded Brass Worm Wheels & Stainless Steel Worm Gear

- Easier Polar Alignment Adjustments

- Support for Larger OTAs with a Longer 2700m Dovetail Saddle

- Remote-Operable with Features such as Home and Limit Optical Sensors

- Improved Cable Management

- Access to Celestron PWI (CPWI) Telescope Control Software

- Adjustable EQ Head Position for Optimal Center of Gravity and an Increased 3°-65° Latitude Range

- Supports Add-On Accessories such as StarSense AutoAlign
