Mounting a Second Telescope (Alt-azimuth
mode only)
The secondary telescope saddle (included) can be installed at
the end of the Atlas Pro mount's counterweight shaft to mount
a second telescope.
1.
Slide the counterweight shaft out and rotate it so the flat
strip at the end of the shaft is facing up, then lock the
shaft with the T-bolt.
2.
Loosen the Allen screw on the secondary saddle's silver
coupler ring and push the saddle onto the counterweight
shaft, as shown in (Figure 16a). Align the Allen screw
with the flat strip on the counterweight shaft.
3.
Use a 5mm Allen wrench to secure the saddle to the
counterweight shaft with the Allen screw in the center of
the saddle (Figure 16b). Also tighten the Allen screw on
the coupler ring with the same wrench (Figure 16c).
4.
Tighten the Dec. clutch, and then install the second
telescope on the secondary saddle. The second
telescope and its saddle should be situated to the left of
the mount when the telescope points forward.
5.
Loosen the counterweight shaft's locking T-bolt to test the
balance of the second telescope. Adjust the positioning
of the telescope in its tube rings or the dovetail bar's
position in the groove of the saddle until the telescope is
balanced. Then retighten the T-bolt.
6.
Loosen the Dec. clutch to check the balance of the
telescope mounted on the primary saddle. Make any
adjustments needed, then retighten the Dec. clutch.
7.
Loosen the counterweight shaft's locking T-bolt and rotate
the second telescope until it points in the same direction
as the main telescope. Lock the T-bolt again.
8.
Aim the main telescope at a distant object, and then
adjust the two vertical-adjustment T-bolts on the
secondary saddle (Figure 16c) to point the secondary
telescope to the same vertical level.
Figure 17 shows the mount in Alt-azimuth mode with the sec-
ondary saddle installed.
Note:
• Use the secondary saddle only when the Atlas Pro
mount is configured in Alt-azimuth mode.
• There is no mechanism on both the primary saddle and
the secondary saddle for aligning the two telescopes in
the azimuth direction.
• The 150mm counterweight shaft extension cannot be
used with the secondary saddle.

silver collar.
