How to Slew the Telescope
This section uses the direction buttons that control the motors. These are the four buttons laid out in a diamond pattern
underneath the control buttons. They will be referred to as the Diamond buttons. It is nice to see the telescope slew when
getting familiar with the operation of the telescope. It turns out, that when observing, the slew function is almost never
used because it is more convenient to move the telescope by hand. This is true for first time users as well as established
amateurs. Here is how to slew the telescope:
