APM 304/3600 APO Triplet with CNC LW II Tube and 3.5" Feather Touch Focuser
The APM 304 is an observatory-class triple-air-spaced super ED APO 12" refractor that offers the observer professional results, both optically and photographically. With this instrument you will cross new observing thresholds! See planetary details with your own two eyes that are similar to those shown on the finest CCD images, or, explore the deep regions of space and capture images that will rival those of professional instruments.
The super strong, lightweight CNC LW II tubes incorporated into the design of the APM 304/3600 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 304/3600 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 304/3600 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. Since this telescope is custom made, the manufacturer will take any requirements you might have into account before building your telescope.
