The CGX 925 HD unites the renowned optical tube EdgeHD 9.25″ and equatorial mount CGX, This makes them ideal for high-resolution imaging, detailed observations and remote-controlled installations. With over 235 mm opening, this system offers an observational power of more than 1100× greater than the human eye.
The model EdgeHD is an optimized version of the classic Schmidt-Cassegrain: it produces a coma-free image, with a perfectly flat field to the edges.
It's a true astrograph, designed to deliver fine stars on the largest sensors, without field curvature.
With a focal length of 2350 mm (f/10), It is ideal for planets and planetary nebulae,
globular clusters, galaxies and deep-sky imaging requiring high resolution.
Treatments StarBright XLT ensure optimum light transmission.
The tube also incorporates :
Visit CGX provides a load capacity of 25 kg, precise engines and mechanics
completely redesigned to fluidify movement, facilitate positioning and improve stability.
It's perfect for advanced imaging setups, even when remotely controlled.
In short, the CGX 925 HD is a top-of-the-range instrument designed for those who want to
a large-aperture telescope capable of delivering impeccable images,
for both visuals and astrophotography. An ideal choice for a personal observatory or remote-controlled installation.
The Moon in great detail and the planets: Jupiter’s bands and moons, Saturn’s rings. With a diameter of 235 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 470× (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 (2,350 mm) by that of the eyepiece: for example, a 25-mm eyepiece provides 94× magnification.
It is an imposing instrument: the tube weighs about 9.53 kg and is about 55.9 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, 2 x 11 lb (5 kg) counterweights, 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 EdgeHD 9.25-inch. Check the connections and focus with your camera.
Select the 9.25-inch ring for this tube. A 12-volt power supply or compatible controller 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.
Recommended diameter: 280 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.
