And it goes without saying that the move from 12 to 16 inches is sure to be immediately obvious to the eye. This chapter takes a look at the largest instruments commonly used by amateurs – those in the 12- to 16-inch aperture class. They offer hug

If you step away from an 8-inch Dob and place your eye at the focus of a 16-inch instrument, the first thing you’ll notice is how much more bright (4-fold) the objects have become. Only af

Once an amateur astronomer gets a look at Omega Centauri or the Orion Nebula (M42) through a 16-inch Dobsonian, chances are he or she will be pining for more aperture. You see, there’s really no substitute for it. More light
