Description

The Celestron CGX-L 1100 EQ 11" f/2.2 Rowe-Ackermann Schmidt Astrograph combines a powerful astrophotography optical tube assembly (OTA) and a ultra heavy-duty research-quality equatorial mount to give users the ability to capture images of near and deep-sky objects like the Moon, planets, nebulae, galaxies, clusters, and binary stars. The optical tube weighs 43 pounds, leaving plenty of pounds in the mount's 75-pound payload capacity for guide scopes, imaging rigs, and just about any other accessories.

Celestron 11" f/2.2 Rowe-Ackermann Schmidt Astrograph v.2 (OTA only)

This updated second-generation Celestron 11" f/2.2 Rowe-Ackermann Schmidt Astrograph v.2 builds on the success and performance of its earlier iteration with the addition of an improved Ultra-Stable Focus System that minimizes both focus shift and mirror flop to improve image quality.

The RASA system is specifically designed for astrophotography and astroimaging with a large 11" aperture and fast f/2.2 focal ratio. The optical tube assembly (OTA) is being offered by itself without a mount and comes with a Celestron CGE-style dovetail plate for use on mounts that accept the larger Losmandy-size mounting system.

Using 4-element rare-earth optical glass lenses ensures accurate color rendition and eliminates aberrations such as coma and field curvatures. The StarBright XLT multi-coating system, which includes anti-reflection coatings on the lenses and highly reflective coatings on the mirrors, increases light transmission throughout the entire optical path. A 12VDC MagLev fan reduces cooldown time and provides optimal airflow through the optical tube while filtering harmful dust from the interior.

The 43.3mm imaging circle is made to cover today's large DSLR and CCD imaging sensors to capture full-frame shots without vignetting, while a fast focal ratio reduces exposure times and background noise without sacrificing image quality and gives you more time for multiple shots of the same object with different filters for later post processing and stacking. Since this OTA is designed as an imaging scope, a 42mm T-thread camera adapter and 48mm camera adapter are provided. Other adapters are available separately if required.

Optical Performance

11" diameter wide-field aperture enables detailed images to be captured of even the faintest deep-sky objects like wispy nebulae
620mm focal length is optimized for wide-field imaging, creating huge mosaics of the night sky, surveying, and comet hunting
Fast f/2.2 focal ratio requires significantly shorter exposures versus slower f/10 OTAs with reduced background noise—this allows more images to be captured, especially with different filters, for post-processing and stacking
Rowe-Ackermann Schmidt Astrograph (RASA) design is purpose built for astrophotography and imaging performance and cannot be used for visual observation
Proprietary StarBright XLT fully multi-coated optical system
Four-element rare-earth glass for true color rendition without aberrations like off-axis coma and field curvature across the entire field of view
42mm T-thread and M48 camera adapters included for attachment to CCD and DSLR cameras
Wide 400-700nm spectral range improves images of deep-space objects like galaxies and nebulae
Internal Ultra-Stable Focus System
Image circle: 43.3mm (1.7")
Resolution: 0.49 arcsec (Rayleigh), 0.41 arcsec (Dawes)
Back focus: 55mm (2.16") with included camera adapter, 72.8mm (2.86") from top of threaded collar
Optical window can be removed and replaced with optional filters such as a light pollution filter
12 VDC MagLev fan reduces cooldown time, provides airflow, and filters dust—runs on eight user-supplied AA batteries or an optional 12VDC power adapter

StarBright XLT Coating System

Multi-layer mirror coatings made from layers of aluminum, SiO2 (silicon dioxide), and TiO2 (titanium dioxide)
Reflectivity is flat across the light spectrum, for both astrophotography/astroimaging and visual observation
Multi-layer anti-reflective coatings made from layers of MgF2 (magnesium fluoride) and HfO2 (hafnium dioxide)
High-transmission water white glass corrector lens with 97.4% light transmission

Ultra-Stable Focus System

Utilizes a linear ball bearing that moves the primary mirror to achieve focus
Minimizes focus shift—unwanted lateral motion of the primary mirror during focusing that causes shifting of the image
Minimizes mirror flop—movement of the primary mirror when the telescope is pointing to different positions in the sky
Compatible with an optional focus motor for even more precise focus control

Mounting

OTA only—mount and tripod required for proper use
Large CGE (Losmandy) dovetail plate makes it compatible with a wide variety of heavy-duty mount heads
OTA weight: 43 pounds; ensure mount and tripod can support this weight plus any additional gear like imaging systems and guide scopes

Celestron CGX-L GoTo EQ Mount with Tripod

With an upgraded payload capacity, tripod, and internal gears, the Celestron CGX-L GoTo EQ Mount improves on their venerable CGX platform to provide users with a heavy-duty research-quality mount for larger optical tube assemblies (OTAs), accessories, and imaging rigs. Engineered to carry a 75 lb payload, and outfitted with high-torque motors and a heavy-duty belt-drive system to improve tracking stability and reduce backlash, it is able to smoothly and accurately track near- and deep-sky objects for extended periods of time.

The Vixen/Losmandy dual dovetail saddle has also been lengthened to 10.6" to improve stability and offer greater security for larger OTAs. To provide a solid platform for the mount and your OTA, a heavy-duty stainless steel tripod is included, sporting massive 2.75"-diameter legs, an accessory tray that doubles as a stabilizer, and an adjustment range from 35.75" to 52.75". The minimum height has been lowered almost a foot versus the earlier CGX model to accommodate a wider range of users and different observation positions.

The brain of the CGX-L is the venerable NexStar+ computer controller. Equipped with a database of 40,000 objects, including the planets, stars, nebulae, galaxies, and the complete Messier catalog, it can also be programmed with up 200 custom user-defined objects with filters added for custom object lists. Its intuitive menu-driven user interface gives you the power to observe the heavens with nine slew speeds, three tracking rates, anti-backlash compensation, and Permanent Periodic Error Correction (PPEC) for smoother movements in the motors and improved tracking over time. Features such as guided tours, extended information on 200 popular objects, and multiple alignment options make the NexStar+ controller easy to use and invaluable to both new users and experienced stargazers.
