APM Telescope 152/1200 APO Triplet with CNC LW II Tube and 3.5" Feather Touch Focuser
The APM 152F/1200 is not only a wonderful, powerful visual APO telescope for lower power, wide-field observations and higher power, super high contrast planetary and double star observations, but it is also a superb imaging machine. The tube assembly has been redesigned to be even more compact and lightweight than previous models. The APM 152F/1200 can now be considered a fully portable high end APO that is solidly at home on medium sized, easily transportable( and relatively inexpensive) mounts. This model can be enjoyed visually with any binoviewer/diagonal combination without the use of a barlow/corrector. When used photographically with a matched field flattener you'll experience coverage up to a 6x7 cm format with pinpoint stars across the entire field...even into the corners!
The super strong, lightweight CNC LW II tubes incorporated in the APM 152F/1200 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 152F/1200 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 152F/1200 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).
