One of the special features of Orion Optics Dobsonians is the ability for existing owners of their OTA or even competitor's OTAs to be able to just drop their tube straight into one of Orion Optics mounts. A further tremendous advantage is the ability to exactly balance the tube to avoid it moving with the weight of added equipment, large eyepieces, cameras, large finders etc. Typical Dobsonian designs are renowned for the tube swinging down when equipment, even of the slightest weight is added. To avoid this, elaborate devices are often used which seldom work properly. More common is to increase the drag on the declination axis thus increasing the drag on those bearings and, as a consequence, creating a severe problem in not allowing smooth adjustment of the telescope's position. With the use of Orion Optics fully adjustable tube cradles and PTFE bearing surfaces you have the capability of adjusting the balance point exactly to accompany the additional equipment you may have added. For absolute perfect axis control, see the optional Friction Brake option below. If you feel the focus mount is not exactly in the most comfortable position for viewing, just rotate the tube for a better, friendlier position.
