Description

The Celestron 0.7x Reducer Lens features a custom 5-element optical design and is engineered to maintain the flat-field performance of the EdgeHD 1400 aplanatic Schmidt optical tube assembly (OTA). This reducer lens provides a substantial 5.75" back focus to accommodate an assortment of imaging accessories. It offers high index optical elements, including extra low dispersion, Lanthanum elements, which provide high contrast viewing while minimizing chromatic aberration. All air-to-glass surfaces are treated with multiple layers of anti-reflection coatings for maximum light transmission and color correction, and the interior of the housing has blackened edges to minimize internal reflection and further enhance image contrast.

The reducer lens features large-diameter lens elements and up to 60mm clear aperture, which ensure that the image circle remains at a generous 42mm for use with large CCD sensors. The mechanical design incorporates a computer-assisted CNC machined aluminum housing for precise spacing and alignment of optical elements and threaded metal covers on the lens assembly to protect your lens from dust and scratches.

Performance

5-element optical layout designed specifically for the EdgeHD 14" Optical Tube Assembly to maintain its flat-field performance
The EdgeHD 0.7x lens provides generous back focus to accommodate additional accessories and a wide variety of cameras. Also allows use of existing EdgeHD T-adapters and other Celestron imaging accessories (sold separately)
Makes your EdgeHD 1400 Optical Tube Assembly one full F-Stop faster than f/11, reducing your exposure time by one-half to capture the same brightness of the object
Increase the field of view by 43%, which is better for capturing wide field images of larger galaxies and nebulae

Glass

The EdgeHD Reducer Lens uses rare earth Lanthanum glass elements for clear, high contrast viewing while minimizing chromatic aberration
All air-to-glass surfaces have multiple layers of coating for maximum light transmission and color correction
All lens elements have blackened edges to minimize internal reflection and maximize contrast

Full Frame Design

Threads directly onto the 3.25" threads of the EdgeHD Optical Tube, which reduces mechanical vignetting and allows for use with larger (full frame) sensors and Off-Axis Guiders
60mm clear aperture lens optimized for a 42mm image circle for use with large CCD sensors

Mechanical Design

Computer-assisted CNC machined aluminum housing for precise spacing and alignment of optical elements
Threaded metal covers for both ends of the lens assembly to protect your lens from unwanted dust and scratches
