As you can see, once you have chosen between refractor or a reflector, if you go a reflector, then you get to choose what mount you put your telescope on. An eq mount or a "dob" mount
Dob is short for dobsonian and is the mount only, but it is now accepted that a dob is the whole telescope and mount
