Model: Apo 105/650 CNC-LW II
The 105mm Apo f/6.2 with the new lightweight and compact CNC Tube and new 3.5" Starlight focuser utilizing a 1:10 fine focus is not only a most powerful visual telescope but also one of the best wide field astrographs on the market. 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
