Celestron EdgeHD 1400 Reducer Lens .7x

Technical Details

Celestron Reducer Lens .7x - EdgeHD 1400 The EdgeHD 0.7x Reducer, specifically designed for Celestron's 14" model, boasts a meticulously crafted 5-element optical design. This design is unique in its ability to maintain the flat-field performance of the EdgeHD optical system. In contrast to standard reducers, it sustains sharpness across the entire field and provides ample back-focus.

This ensures smooth compatibility with an extensive array of imaging accessories and camera configurations, facilitating quicker imaging and a broader field of view.

Key Features

• 5-element optical design
• Full f-stop increase in speed
• Field of view expansion by 43 percent
• High-index optical elements
• Full Frame Imaging Capability
• Advanced Optical Glass and Coatings

High-index optical elements, including extra-low dispersion and rare-earth lanthanum glass, provide excellent contrast whilst minimising chromatic aberration. All air-to-glass surfaces are fully multi-coated to maximise light transmission and enhance colour accuracy.

Blackened lens edges further reduce internal reflections, delivering improved contrast and overall image clarity.

Full Frame Imaging Capability

With large diameter lens elements and a 60mm clear aperture, the reducer produces an optimised 42mm image circle suitable for full-frame sensors and large CCD cameras.

It threads directly onto the 3.25" rear cell of the EdgeHD optical tube, reducing mechanical vignetting and enabling the use of off-axis guiders and other advanced imaging accessories.

Precision Engineering and Durable Construction

The housing is CNC machined from aluminium to ensure precise alignment and spacing of the optical elements, maintaining consistent performance in demanding conditions. Threaded metal covers are included on both ends of the lens assembly to protect the optics from dust and scratches when not in use.

Versatile Imaging System Integration

When paired with the Fastar capability of the EdgeHD system, this 0.7x reducer provides an ideal intermediate focal length between the native f/11 configuration and optional f/2 imaging setups.

This versatility allows astrophotographers to adapt their equipment for a wide range of imaging scenarios, making the EdgeHD platform one of the most complete and flexible imaging systems available in its class.
