APM - LZOS Telescope Apo Refractor Astrograph 105 f/4.6 - 42mm 2.5"ZTA

If you like to safe a little bit money, our Super-ED Apo 105/650mm with the APM 2.5" ZTA focuser should be interesting. 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.

This variant comes with a high quality 2.5" APM ZTA focuser. 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.

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 latest large CCDs.
