Loosen the right ascension (R.A.) clutch with the
handle (Figure 8a), and rotate the R.A. axis until the
counterweight shaft is pointing toward the ground, as in
Figure 7b.

The Atlas Pro mount comes with a 150mm counterweight
shaft extension (Figure 9), which can be installed at this
point if necessary for balancing heavier payloads. Ensure
that the extension is tightly secured before installing
counterweights.
5.
Loosen the counterweight's lock knob and slide one or
more counterweights onto the counterweight shaft as
needed to balance your instrument. (See Section 2.5 for
details on how to balance the telescope.) Retighten the
lock knob to secure the counterweight on the shaft.

Replace the safety stop on the end of the counterweight
shaft. The safety stop prevents the counterweights from
falling on your foot if the lock knobs come loose.

Installing a Telescope on the Mount
The Atlas Pro mount is designed to hold a telescope payload
of up to 44 lbs. For heavier telescopes, the mount may not
provide sufficient stability for steady imaging.
1.
Before installing a telescope, be sure that:
• The counterweight shaft is pointing toward the ground.
• The counterweights are installed on the counterweight
shaft and have been moved to the bottom end of the
shaft.
• The R.A. axis is secured by tightening the R.A. clutch.
2.
Loosen the two clamp knobs on the primary dual-width
saddle plate (Figure 10) until the width of one of the
