Step 5. Set telescope to PARK POSITION

If you are using the telescope for land object observing, skip to Step 6.

(1)Loosen the altitude clutch; point the telescope tube directly up at the zenith. Tighten the clutch.

(2)Position the mount so that the “N-S” mark is aligned with the earth’s magnetic north and south poles (a compass may be helpful).

(3)Level the mount using the bubble on the mount by adjusting the height of the mount base or tripod legs.
