APM - LZOS Telescope Apo Refractor Astrograph 105 f/4.6 - 52mm 3.5" FT

For sure we also offer this great lens with our fantastic M82 Riccardi reducer/corrector. The result of popular developments in recent years is the new 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 M82, 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 52mm.

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 M82 Reducer with f/4.6 it is also an excellent astrograph. This system, with the specially matching field flattener / reducer generates a fully illuminated and corrected field for full-format cameras and shows pin-point star images right into the corners, even with the latest large sensors.
