Celestron Reducer Lens 0.7x for EdgeHD 800
- Reducer 0.7x
- the four-lens reducer for 8 inch EdgeHD has a special optical design that retains the flattened field of view of the EdgeHD telescopes. Unlike universal reducers, it also offers sufficient backfocus for a wide range of photographic accessories.
- the 0.7x EdgeHD reducers contain lenses with an extreme refractive index, including lanthanum lenses with very low dispersion. As a result, the particularly high contrast of the EdgeHD optics remains undiminished despite the many additional lenses and there is no color aberration over a very wide spectral range.
- each glass-air surface in this lens system is multi-coated to maintain maximum transmission and color fidelity. All lens edges are carefully blackened to completely suppress internal reflections.
- the elaborate CNC-milled aluminum housing ensures exact spacing and alignment of the lenses. Metal screw caps protect the lenses from dust and damage.
- together with the f/2 HyperStar option and the f/7 Edge-HD reducer, the f/10 Celestron EdgeHD Schmidt-Cassegrain optics are by far the most versatile telescope optics in their price class
- suitable for EdgeHD 1400
Reducer 0.7x EdgeHD 800
Design: four-lens reducer that retains the flat field of view of the Edge HD telescopes
105mm backfocus at f/7 (133.35mm at f/10) allows for a variety of accessories and cameras. The optional EdgeHD T adapter is in two parts and accepts DSLR cameras with T2 bayonet rings which have a flange focal distance of 55mm. This adapter therefore serves both distances.
A full f-stop faster than f/10: Reduces the exposure time by half with the same image brightness.
Enlarges the image field by 43%: Ideally suited for large field images, e.g. of large-scale galaxies and nebulae.
Glass
Lanthanumglass elements:
In the EdgeHD reducers, lenses made of lanthanum enable clear, high-contrast images with minimal chromatic aberration
Fully multi-coated lenses: All glass air surfaces are multi-coated for maximum light transmission and color fidelity
Blackened lens edges: All lenses have blackened edges to eliminate internal reflections and increase contrast
Optimized for APS-C format sensors: Fits most DSLR cameras as well as Nightscape CCD cameras
Mechanics
Aluminum housing:
CNC-machined aluminum housing for precise lens spacing and alignment.
Metal screw cap for both ends of the reducer: Protects the optics from dust and scratches.
Features:
The EdgeHD 0.7x reducer makes e.g. Your EdgeHD 1100 Schmidt-Cassergrain by a full aperture faster than f/10, halving the exposure time required to achieve the same image brightness
Optics with four lens elements
Provides a comparable flat image to the original EdgeHD optics
Enlarges the field of view by 43%
105mm backfocus, which means enough room for modern optical accessories and a variety of cameras
Allows the use of existing EdgeHD T-adapters with or without EdgeHD reducer
