The CGX 1100 HD combines the powerful optical tube EdgeHD 11″ to the frame equatorial CGX, two pieces of equipment delivered together. This package is one of the best choices for those looking for a large diameter, impeccable image quality and a solid mount, designed for detailed observations and advanced astrophotography.
The EdgeHD 11″ is an aplanatic Schmidt-Cassegrain telescope that delivers images perfectly clean and flat over the whole field. With an aperture of 279 mm and a focal length of 2800 mm (f/10), it combines enormous light-gathering power with exceptional resolution, ideal for planets, galaxies, planetary nebulae and globular clusters.
Coatings StarBright XLT for maximum brightness and contrast. The tube also incorporates :
The frame CGX, included with the telescope, offers a load capacity of 25 kg and a robust mechanical assembly designed to support the 11″ tube while ensuring smooth and reliable tracking. It is suitable for both visual observation and demanding imaging setups, including remote-controlled operations.
In short, the CGX 1100 HD is a complete system that comes with the EdgeHD 11″ telescope and the CGX mount. It offers an exceptional combination of optical power, stability, and precision. It is an ideal choice for advanced astronomers and astrophotographers looking for a large-aperture instrument capable of unlocking the full potential of deep-sky objects.
The Moon in great detail and the planets: Jupiter’s bands and moons, Saturn’s rings. With a diameter of 279 mm, it captures a great deal of light: under a very dark sky, bright galaxies and nebulae become visible. Its maximum useful magnification is approximately 558× (2 × the diameter in mm); in practice, atmospheric turbulence often limits observation to lower magnifications.
No eyepiece is included with this model. The magnification is calculated by dividing the telescope's focal length (2,800 mm) by that of the eyepiece: for example, a 25-mm eyepiece provides 112× magnification.
It is an imposing instrument: the tube weighs about 13 kg and is about 61 cm long, and the mount weighs about 20 kg (plus 8.7 kg for the tripod).
Rarely. The optics are adjusted at the factory; from time to time, a star test is sufficient: point the telescope at a bright star, defocus it slightly, and the rings should be perfectly concentric. If necessary, adjustments can be made using the screws on the secondary mirror.
Yes: The motorized equatorial mount tracks the movement of the sky, allowing for exposures of the Moon, the planets, and bright deep-sky objects. Its ST-4 autoguiding port then enables longer exposures.
CGX equatorial mount, CGX tripod, accessory plate, 3 counterweights (11 lb / 5 kg each), NexStar+ hand controller, 8 mm Allen wrench, 12 V DC power cable, hand controller holder.
No. The Celestron CGX mount does not come with a power supply (only a 12-V cable is included). Power requirements: 12 V DC, 4 A. For home use, we recommend the'Pegasus Astro 12 V 10 A power supply with a 5.5 × 2.1 mm plug : regulated 12.5 V output, high current reserve, and it will later be able to power a Pegasus hub (Pocket Powerbox) for the camera and the anti-fog heating elements.
Here are a few accessories we've selected for this model, depending on your needs.
Optional 0.7× reducer for the 11-inch EdgeHD. Check the connections and focus with your camera.
Choose the 11-inch ring for this tube. A controller is recommended to regulate the heat; a suitable power supply must be purchased separately.
Motorized rear eyepiece holder that complements the mirror adjustment. Be sure to use the SC 3.3″ adapter (PL3600362); check the connections, back focus, load, and clearance with your mount and any reducer you may be using.
Optional motor for focusing the primary mirror. Check the shaft diameter, adapters, clearance, and 12-volt power supply. A rear eyepiece holder, if present, serves a different purpose and is not required for this motor.
Recommended diameter: 320 mm. Check the measurement and the mounting.
Recommended diameter: 350 mm. Check the measurement and the mounting.
For extended dew shield, Losmandy-compatible rail, and Cover V4 Pro-EC or Eclipse. Without extended dew shield: short kit.
