One of the special features of this Dobsonian mount is the ability for owners of Orion UK Newtonian OTAs (and other brands) to be able to just drop their tube straight into this rockerbox. It holds Newtonian telescopes up to 8" of aperture.
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 our 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. 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.
Mount includes: Rocker box, all PTFE bearing surfaces, polymer non scratch screw on feet, declination CNC machined bearing rings. To fit an OTA, tube rings and blocks are required to suit your OTA size.
