Sky & Telescope’s Hot Products 2019 Award

"Incredibly fast optical speeds allow deep-sky imaging with short exposures, opening up a new world of scientific- and recreational-astrophotography possibilities."

Product Highlights
  • Large 11"-Diameter Aperture
  • 620mm Focal Length / f/2.2 Focal Ratio
  • StarBright XLT Optical Coating System
  • Motorized Computer-Controlled CGX Mount

The Celestron CGX 1100 EQ 11" f/2.2 Rowe-Ackermann Schmidt Astrograph combines a powerful astrophotography optical tube assembly (OTA) and a 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 extra payload capacity for guide scopes, imaging rigs, and other accessories. This near-research grade astrograph combination is ideal for imaging at home or at more remote sites.

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 GoTo EQ Mount with Tripod

Celestron's CGX GoTo EQ Mount with Tripod improves on their venerable CGEM 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 55-pound payload and outfitted with high-torque motors with 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 long periods of time. Its Vixen/Losmandy dual dovetail saddle makes the mount compatible with most plates in use today. To provide a stable platform for the mount and your OTA, a heavy-duty stainless steel tripod is included that sports large 2"-diameter legs, an accessory tray that doubles as a stabilizer, and an adjustment range from 47.25 to 77.5" including the head.

The brain of the CGX EQ is the 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 to 100 custom user-defined objects and filters for custom object lists. Its intuitive menu-driven user interface allows you to observe the heavens with nine slew speeds and three tracking rates, plus 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 new users and experienced stargazers.
