APM 175/1400 APO Triplet with CNC LW II Tube and 3.5" Feather Touch Focuser
The APM 175/1400 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, and is still considered transportable. The APM 175/1400 is a high end APO that is solidly at home on either a medium sized, transportable mount or in an observatory on a high-end mount with pier.
The super strong, lightweight CNC LW II tubes incorporated into the design of the APM 175/1400 refractor 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 175/1400 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 in the APM 175/1400 APO package are flat on both sides and have five tapped 1/4-20 inch holes perpendicular to the tube line with one centered. The middle two hole's center to center spacing is 60mm (2.362") and the outer two hole's spacing is 3.2" (Astro-Physics standard).
