Celestron 0.7x Reducer Lens for EdgeHD 1400

Celestron EdgeHD 0.7x Focal Reducer – 14” EdgeHD

Unlock the full astrophotographic capabilities of your 14” EdgeHD optical tube with Celestron’s premium 0.7x Focal Reducer. Engineered with a sophisticated 5-element optical design, this reducer preserves the award-winning flat-field performance of the EdgeHD system while delivering faster imaging speeds and a wider field of view.

Unlike generic alternatives, this reducer offers generous back focus, ensuring compatibility with a wide array of imaging accessories and full-frame sensors—making it the ideal tool for advanced astrophotographers.

Optical Performance

• Optimised for EdgeHD 14”
  Custom 5-element optical design maintains the flat, coma-free field across large sensors, preserving pinpoint stars edge to edge.

• Faster Imaging
  Reduces your focal ratio from f/11 to f/7.7, allowing you to cut exposure times in half without sacrificing image quality.

• Expanded Field of View
  Increases your imaging area by 43%, ideal for capturing large-scale celestial objects like nebulae and galaxies.

• Lanthanum Glass Optics
  Incorporates high-index Lanthanum elements to minimise chromatic aberration and enhance contrast for sharp, colour-accurate results.

• Fully Multi-Coated Lenses
  Advanced coatings on all air-to-glass surfaces maximise light transmission and improve overall image brightness and fidelity.

• Blacked Lens Edges
  Reduces internal reflections and boosts contrast—critical when imaging faint, deep-sky subjects.

Full-Frame Imaging Ready

• 60mm Clear Aperture
  Designed to accommodate full-frame sensors with a 42mm image circle, ensuring maximum coverage with minimal vignetting.

• Direct Thread Connection
  Attaches directly to the 3.25" rear threads of the EdgeHD 14”, enhancing rigidity and reducing optical path obstructions—ideal for heavy imaging payloads.

• Off-Axis Guider Compatible
  Maintains the native back focus of the EdgeHD system at f/11, allowing use of Celestron T-adapters and guiding accessories without additional spacing requirements.

Premium Mechanical Construction

• CNC-Machined Aluminium Housing
  Precision-machined for accurate optical spacing and alignment, ensuring consistently sharp images across the frame.

• Protective Metal End Caps
  Threaded covers on both ends of the reducer keep the optics safe from dust and damage during storage or transport.

System Integration & Flexibility

Combine the 0.7x Reducer with your EdgeHD 14” and the optional Fastar system to create a truly versatile imaging platform, capable of f/11, f/7.7, and even ultra-fast f/2 capture speeds. From narrowband deep-sky imaging to fast snapshots of wide nebulae, this setup offers unmatched adaptability in its class.

Key Benefits at a Glance:

• Custom 5-element reducer designed specifically for the EdgeHD 14”

• Reduces focal length for wider, faster imaging (f/11 → f/7.7)

• Maintains flat-field correction across full-frame sensors

• High-quality Lanthanum and ED glass for optimal clarity and contrast

• Full 60mm aperture and 42mm image circle for large sensor support

• Durable, protective mechanical design with threaded connections

Whether you’re upgrading for deep-sky astrophotography or building a robust imaging rig for professional results, the Celestron EdgeHD 0.7x Reducer for 14” is the optical upgrade that delivers performance, versatility, and imaging excellence.
