Our OD400S and L is one of our most popular Dobsonian models. Being f4 / f/5.3 the tube easily fits across the back seat of a family car with room to spare. Weighing less than 25 Kg, it is an ideal quick set up medium sized instrument with minimum weight. The mounting is made from aluminium plate, similar to that used in aircraft production and is incredibly strong and coated with hard polymer for scratch resistance.
