Remove the dust cover from the other end of optical tube
assembly.
Use the focus knob
to bring objects into focus. You may
need to turn the focus knob quite a few turns to focus your
telescope for the first time. Always start observing using a
low power eyepiece (such as a 25mm eyepiece) to get a nice
wide field of view. Later you can change to high power if so
desired. Higher powered eyepieces have a much narrower
field of view. So it’s more difficult to initially locate objects
using higher powered eyepieces.
