Sayfayı Yazdır1. If you examine the polar axis assembly, you will see that the center of the polar shaft is hollow. You may need
to rotate the internal Dec. shaft by moving the top of the Dec. axis (or the cradle plate if it is attached) to align the
sight hole that has been drilled into it. Now, you can look through the shaft to the other side. The end of the R.A.
axis is threaded to accept the optional polar axis telescope used for polar alignment.
2. Loosen the two ½-13 socket head bolts on each side of the mounting using the 3.8" hex key provided. Use the
3/16" hex key to loosen the ¼-20 socket head cap screw on each side of the mount base.
3. Move the polar axis up or down and the entire pier east or west until Polaris is visible through the hollow shaft
of the polar axis.
4. Fine azimuth adjustments: With the mount now oriented approximately towards the pole, use the two small
black knobs on each side of the mount to make fine adjustments in azimuth. You must back off the opposing
azimuth knob in order to move the other knob in that direction.
Fine altitude adjustments: These adjustments are made with the large black knob moving the polar axis up and
down. We have found that fine altitude alignment can be made also by using the turnbuckle on the north leg of
the pier.
5. At this point, you have achieved rough polar alignment, which may be sufficient for most casual visual
observations. When the R.A. motor is engaged, it will compensate for the rotation of the earth and keep the
target object within the eyepiece field of view. Your target object will slowly drift since polar alignment at this
stage is only approximate. However, you can make corrections with your hand controller, as we will discuss later.
6. If rough polar alignment is sufficient, snug the two ½-13 screws and two 1/3-20 screws to lock the mount into
position.
POLAR ALIGNMENT:
Follow these instructions if you want to fine-tune the polar alignment of your mount. If not,
you may skip this section and move onto "Assemble Cradle Plate and Counterweight Shaft".
1. Polar axis telescope – The pole can be viewed through the polar axis with our optional polar axis telescope.
Please read the instructions that were included with the polar axis telescope.
2. If you don't have a polar axis telescope, you may use the star drift method.
3. When the proper alignment has been achieved, snug the two ½-13 screws and two ¼-20 screws lightly to
secure the polar axis and recheck alignment. If no movement has occurred, finish tightening the two bolts as
much as possible to prevent movement when the telescope and counterweights are attached.
IMPORTANT: Failure to tighten the side bolts can cause the axis to slip, with resultant damage to the mount.
ASSEMBLE CRADLE PLATE AND COUNTERWEIGHT SHAFT:
1. Attach the cradle plate to the Dec. axis with the four ¼-20 x 5/8" screws provided. The cradle plate should not
cover the Dec. clutch knob. Screw the counterweight shaft to the Dec. axis. Please refer to Diagram 4.
NOTE: During disassembly, the cradle plate may remain attached to the declination axis or removed as
desired.
IMPORTANT: Always attach the counterweights before mounting the telescope to prevent sudden
movement of an unbalanced tube assembly, which may cause damage or injury. Remember that the
counterweights are heavy and will hurt if they fall on your toe.
2. Remove the hand knob and washer from the base of the counterweight shaft. Add sufficient counterweights to
the counterweight shaft to balance the telescope you intend to use. Always use two hands to attach or move
