APM TMB 130/780 CNC-LW II APO Telescope

These tubes are made in Germany with non-compromising mechanical quality. The dew cap slides smoothly over the tube without producing any paint scratches. The focuser is a full 3.5" size. 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 position. The finder bracket has a quick exchange style screw system and is mounted on the rotatable focuser, which allows focuser rotation to bring the finder scope to the most comfortable observing position. The focuser comes with large anodized focuser knobs and moves extremely smooth when racking. The focuser comes with a screwed on 3.5"/2" adapter and a 2"/1.25" clamp ring style adapter to protect your eyepieces and diagonals from scratches. The tube rings are flat on both sides and offer three tapped 1/4-20 inch holes perpendicular to the tube line with the outer two hole's center to center spacing of 60mm (2.362"). The center tapped hole can be used for different mounting plates with only a single center hole. The tube's internal baffles are matched for a large usable photographic field . This system with the matched field flattener for 6x7 medium format film offers a image circle of appropriate size. This APM TMB 130F/6 is not only a wonderfull powerfull visual APO for lower power widefield observations and highest power, highest contrast planetary and doupbe star observations, but also a superb imaging maschine. By adding the matched designed 6 x 7 fieldflattner if will offer you pin point stars across the entire field to the outer edges either by use of new larger CCD cameras or medium format cameras like the Pentax 6 x 7.
