APM Telescope 130F/780 APO Triplet Refractor with CNC LW II Tube
The APM 130mm f/6 triple air-spaced Super APO refractor offers up perfect color and spherical correction. The 130mm (5.12") objective not only pulls in more light than a 4" model, you can also push the magnification on planets and double stars! The super strong, lightweight CNC LW II tubes are manufactured in Germany of the best materials and with fine attention to details and overall mechanical quality. The dew shield slides smoothly over the optical tube assembly without scratching the paint. The tube's internal baffles are matched for a large usable photographic field.
The Starlight Instruments Feather Touch focuser included with the APM 130F/780 APO is a full 3.5". It rotates smoothly and with zero image shift. This zero shift rotation is very important when your camera has already achieved its best focus and you would like to rotate it to the best possible position. The 50mm quick release finder bracket and dovetail base are mounted on the fully rotatable focuser, allowing you to rotate your finder, just like your camera, to the best position. The Feather Touch focuser comes with large anodized knobs, an attached 3.5" to 2" adapter and a 2" to 1.25" clamp-style adapter to protect your eyepieces and diagonals from scratches.
The included tube rings with the APM 130F/780 APO are flat on both sides and offer three tapped 1/4-20 holes perpendicular to the tube line. The center spacing between the two outer holes is 60mm, or 2.362". The center tapped hole can be used for mounting plates that only have a single center hole.
What's more you get special glass type OK-4 - designed and melted in LZOS - which allows to achieve perfect color correction within visible range of spectrum. OK-4 glass similar to fluorite has unique optical parameters. Made of OK-4 apo-lenses (apochromatic lenses) ensure image quality characterized by round-mean-square wavefront deviation not exceeding 0.035 wavelength (532nm).
