Dobsons are alt-azimuthal telescopes, as everybody knows. This may be a disadvantage if you want to observe planets at say 400x. It does work, of course, but it requires some practice and smooth operation of the telescope mount. Nevertheless, it would be nice, if Jupiter would just stay in the middle of your field of view.
There is a relatively simple method to realize an equatorial mount for Dobsonians, particularly if you are interested in visual use only. More..........
