Locate the back of your telescope and notice the 3 pairs of screws with one screw sticking further out than the other in each pair.

Remove the three 19.1 mm lower resting screws from your telescope using a Phillips #1 screwdriver.

While unfastening the 3rd screw, palm the back panel of your telescope so it doesn't fall off unexpectedly.

Carefully pull back the loose panel exposing the primary mirror and set it aside.
