6. Determine the latitude range that you need (refer to Diagram 3)
and position the hole that is marked “A” in Diagram 5 at that
location. Note that this hole is located at the rounded part of the
altitude bar.
7. Attach two of the screws (one on either side of the adjuster bar),
but do not tighten. Rotate the altitude adjuster bar around this pivot
point until one of the other holes lines up. Insert the remaining two
screws. Lightly tighten so that you still have some ability to move
the bar.
8. Note that the altitude adjustment knob is attached to a threaded
rod that travels through the altitude adjuster bar. Turn the knob so
that the altitude adjuster bar is positioned approximately in the
middle of the threaded rod. You should see about half of the
threaded rod protruding from both sides of the altitude adjuster
bar. This will allow you to move the mount fully within the altitude
range.
9. At the end of the threaded rod mentioned in the last step, you will
see a small brass altitude adjuster thrust pad. This is the part that
will come in contact with the polar axis as you ease it back into
position. Loosen the altitude locking knob (motor/gear side) and
lower the polar axis so that it rests comfortably on this pad. The
threaded rod should be positioned at a right angle to the polar axis
housing. Firmly tighten the altitude adjustment screws.
10. Turn the altitude adjustment knob to raise or lower the polar axis to your approximate observing latitude. Tighten
the altitude locking knobs with finger pressure only. You do not need to tighten with the hex key.
11. Firmly tighten both polar axis pivot screws with the hex key.
Attach Pier Adapter to Pier Post
If you purchased the pier from Astro-Physics, the pier top adapter of the 1200 may be already attached to the top of the
pier. If you are constructing your own pier or tripod, you will need to incorporate this part. The pier adapter was designed to
fit into a 10" x 0.094" wall tube. Use six (6) screws to attach this part. Note that with the Astro-Physics pier, you can orient
the pier adapter so that one of the pier legs faces "north" or "south" as you prefer.
Assemble Pier (purchased separately)
Begin by assembling the portable pier at the
desired observing location. Note which
direction is north.
1. Slide the three legs onto the nubs of
the base and rotate the assembly so
that one of the legs points toward
north (or south, if that is your
preference).
2. Place the pier post on the base
orienting the center azimuth block
directly north. If you choose to have
one leg north, then the pier adapter
plate will have to be installed with the
azimuth block directly over a
turnbuckle. If you have one leg south,
the pier adapter plate will have to be
installed with the azimuth block over
and between two of the pier post
turnbuckles.
3. Attach the tension rods. The
turnbuckles should be drawn tight
until the whole assembly is stiff enough to support your weight without movement.
