Key Features:

• Increased Aperture: The 9.25-inch model provides more light-gathering power (34% more than the 8"), allowing for better views of fainter deep-sky objects.
• Improved Field of View: Larger aperture offers brighter and sharper views, especially for observing or imaging distant galaxies, nebulae, and other faint objects.
• Better for Deep-Sky Imaging: With the EdgeHD optics, this scope ensures flat-field imaging, ideal for wide-field astrophotography.
• CGX Mount Features: The same advanced tracking and support for heavy imaging equipment, with the mount handling payloads of up to 55 lbs.

Best For:

• Intermediate astrophotographers who need an improved aperture for capturing deep-sky objects.
• Advanced visual observers wanting better detail and performance over the 8".

3. CGX EdgeHD 11"

• Aperture: 279 mm (11 inches)
• Focal Length: 2800 mm (f/10)
• Optical Tube Weight: 28 lbs (12.7 kg)
• Total Weight with CGX Mount: Approx. 95 lbs (43 kg)
• Mount Type: CGX Equatorial Mount
• Payload Capacity: 55 lbs (25 kg)

Key Features:

• High Light-Gathering Ability: The 11-inch aperture gives you a significant boost in light-gathering power (89% more than the 8"), which means more detail in faint deep-sky objects.
• Improved Resolution: The 11" EdgeHD provides sharp, high-resolution imaging, making it a solid choice for both planetary and deep-sky imaging.
• Astrophotography Powerhouse: With its larger aperture and longer focal length, this model is capable of producing highly detailed images of planets, galaxies, and nebulae.
• Robust Mount: The CGX mount provides precise tracking and stability, even when loaded with imaging accessories, guidescopes, and other astrophotography gear.

Best For:

• Serious astrophotographers and advanced visual astronomers who require high resolution and a larger aperture for long-exposure imaging and detailed visual observations.
• Deep-sky enthusiasts who need the extra aperture for fainter objects and distant galaxies.

4. CGX EdgeHD 14"

• Aperture: 355.6 mm (14 inches)
• Focal Length: 3910 mm (f/11)
• Optical Tube Weight: 46 lbs (20.87 kg)
• Total Weight with CGX Mount: Approx. 106 lbs (48 kg)
• Mount Type: CGX-L Equatorial Mount
• Payload Capacity: 75 lbs (34 kg)

Key Features:

• Largest Aperture: The 14-inch model is the largest and most powerful in the CGX EdgeHD lineup, offering 2589x light-gathering power compared to the human eye, which allows it to resolve even the faintest and most distant objects.
• Ultra-High-Resolution Imaging: Perfect for research-grade astrophotography or professional-level observations. The high resolution (0.29 arcseconds) is ideal for capturing high-detail images of planets, galaxies, and nebulae.
• CGX-L Mount: Paired with the CGX-L mount, this setup can handle heavier payloads (up to 75 lbs), making it suitable for complex astrophotography setups that include multiple imaging and guiding instruments.
• Observatory-Grade Setup: Given the size and weight, this telescope is ideal for permanent setups in observatories or semi-permanent installations.

Best For:

• Professional astrophotographers and research astronomers who need the best possible resolution and aperture.
• Permanent or semi-permanent observatories where transport and setup are not concerns.
• Users aiming to observe or image the faintest and farthest objects in deep space, such as distant galaxies, nebulae, and clusters.
