APM - LZOS Telescope Apo Refractor Astrograph 105 f/4.6 - 42mm 3.5"ZTA

The bigger brother of the 100/800mm is the high quality Super-ED Apo 105/650mm. The result of popular developments in recent years is the Super ED Apo series from APM. LZOS has specially developed a new type of glass that comes extremely close to fluorite without having to accept the difficult properties of fluorite. This extreme ED glass characterizes this very high-quality lens series, which is extremely efficient and at fair, affordable prices.

The "small" 105/650mm comes with a large 3.5" FeatherTouch™ focuser, which is famous for its excellent quality. Features: 360° rotatable and separately clampable, 1:10 micro reduction, adapter to 1.25" is included. The tube is of course internally optimized and stable, the dew cap can be retracted, the front and rear end caps and a connection system for a viewfinder are on board.

With the Riccardi Reducer M63, the focal length is reduced to 488mm, whereby the aperture ratio is reduced from f/6.2 to f/4.6. The fully corrected image circle is 42mm with less than 10% vignetting on the edge and 52mm with less than 30% vignetting on the edge.

The APM/LZOS 105 f/6.2 is not only a wonderfully powerful visual apochromat for observations at low magnifications for planets and double stars at high magnification with the highest contrast. But with the Riccardi M63 Reducer with f/4.6 it is also an excellent astrograph. This system, with the specially matching field flattner / reducer generates a fully illuminated and corrected field for full-format CCDs and shows pin-point star images right into the corners, even with the latest large CCDs.
