APM 254/2250 APO Triplet with CNC LW II Tube and 3.5" Feather Touch Focuser

The APM 130mm f/9.2 triple air-spaced Super APO refractor offers up perfect color and spherical correction, and you will not believe high resolution, high contrast results on the planets! The 130mm (5.12") objective not only pulls in more light than a 4" model, it allows you to 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 super strong, lightweight CNC LW II tubes incorporated into the design of the APM 254/2250 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 254/2250 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 254/2250 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).

Please note: This optical tube assembly is rather front-heavy. For an additional fee, the factory will install additional weight to the rear portion of the tube, at the balancing point of your choice. If you are interested in this upgrade, please contact OPT and we will investigate your options and pricing for you. Image shows APM 254/2250 with optional Paramount and accessories.
