Reducer for 800 Edge HD
The EdgeHD Reducer offer a specially designed for the EdgeHD
Telescopes calculated optics with five optical elements (including with
lanthanum glass), while maintaining the flat field of view of the EdgeHD
optics.
Shorten in contrast to simpler reducers for the APS format
Edge-HD Reducer does not match the original backfocus of 146 mm. Through this
Not only can any DSLR camera be connected, but also
all known CCD cameras with filter wheels and (AO) active optics
systems and off-axis guiding adapters.
The 0.7x EdgeHD Reducer contain lenses with extreme refractive index,
including very low dispersion lanthanum lenses. As a result, remains
the particularly high contrast of the Edge HD optics despite the many
additional lenses get undiminished and it arises over a
no chromatic aberrations over a very wide spectral range.
Each glass-air surface in this lens system is designed to obtain maximum
Transmission and color fidelity multi-coated. All lens edges
are carefully blackened to completely eliminate internal reflections
suppress. The large lenses with a diameter of up to 60mm
enable a fully illuminated image circle with a diameter of 42mm
– also suitable for large CCD sensors.
The complex CNC-milled aluminum housing provides the exact
distances and precise alignment of the lenses. screw cap
Made of metal protect the lenses from dust and damage when the
Edge HD Reducer is not used.
Along with the f/2 HyperStar option and the f/7 Edge HD reducer
the f/10 Celestron EdgeHD Schmidt-Cassegrain optics for far
most versatile telescope optics in its price class.
Allows the use of existing EdgeHD T-adapters with or without
