i have a 12 inch bintel solid tube dob. it lives in the carport with one of the silver covers from ebay on it when not in use. its the older style with the teflon sliders. ive fitted a lazy susan bearing to the base and it spins easily now. i see they have the adjustible tension nobs on the tube now( got to better than taking one of the springs off) i have made a trolly to move it around cause set up it is nasty to drag. at high mag its a bugger to keep say planets in sight and once you lose it it takes an eyepiece change(or zoom) to line it up for another 5 seconds veiwing. wide field views are fantastic, so much stuff up there. for high mag id look for some tracking dob with a goto mount. the goto mount from andrews is the next purchase id like to make, have to save up for it though$$.
