APM / LZOS Astrograph 105 mm f / 4.6, 52mm image circle, 3.5 "Starlight excerpt
APM-LZOS 3-lens SuperED astrograph in the new special package with Riccardi M82 reducer
The dew cap and the main pipe are made of Kruppax 50, all other parts are made of high quality aluminum, CNC turned or milled. Tube and dew cap are painted with RAL 9001 cream white, the aluminum parts are painted black. The dew cap is screwed and slidable for the purpose of shorter transport length and ends in the front area with an inner panel, which effectively suppresses dew in the optics over a longer period of time.
The 3.5 "focuser works with a high-precision rack that is adjustable with the drive pinion and can be rotated by 360 ° without any play. The possibility of rotation without play is particularly important in photography to first set the focus and then to determine the best section by rotating .
The 50 mm viewfinder bracket is attached to the extension itself with a quick-change device, which is so precisely worked that it remains constantly adjusted even after the viewfinder has been changed several times.
The extension ends with a reducing adapter 3 "-2" with clamping ring and an adapter 2 "-1.25" with brass clamping ring. The complete extension with viewfinder holder can also be rotated through 360 °, so that the viewfinder can always be brought into the most comfortable position for you, the attached and focused 35mm or medium format camera can always be rotated into the desired position, but also so that you can take your star diagonal with you You do not have to loosen the eyepieces when you change the position of the sky, just turn the extension. The rotation and the focusing drive can be clamped using a hand screw.
The pipe clamps are made of black powder-coated, CNC machined aluminum and come with a flat base, a central thread 1 / 4-20 "and 2 outer threads 1 / 4-20" with 60 mm hole spacing (Astrophysics standard).
The APM / LZOS 105 F / 6.2 is not only a wonderfully powerful visual apo for observing at low magnifications and planets and double stars at high magnification with the highest contrast, but also an excellent one with the Ruiccardi M82 Reducer with f / 4.6 Astrograph. This system with the specially matching field flattner / reducer generates a fully illuminated and corrected field for full format CCDs and generates pin-fine star images right into the corners, even with the latest larger CCDs.
With the Riccardi Reducer M82 the focal length is reduced to 488m, whereby the aperture ratio is reduced from f / 6.2 to f / 4.6. The fully corrected image circle is 52mm.
