ASTRO-PHYSICS 900 German Equatorial 빠른 시작 매뉴얼

altitude position). Some resistance will be

felt with this operation as you are pushing

against the weight of the polar housing and

the resistance of the remaining polar axis

pivot screw (which has not been loosened).

Before attempting to remove or move the

altitude adjuster bar, you must tighten the

altitude-locking knob on the motor/gear

housing side. This will prevent any

downward movement of the polar axis during

positioning of the altitude adjuster bar.

While supporting the altitude adjuster bar,

remove the two screws that support it on

each side (4 screws in all). If upgrading,

gently remove your old Altitude Adjuster Bar.

If you are changing latitude positions, keep

the two ends of the bar in contact with the

side of the mount, don't remove it completely (this tip is for your convenience).

Determine the latitude range that you need and position the altitude adjuster bar so

that the hole that is marked "A", as shown in the diagram, is located at the

appropriate hole position numbered 1-4 in the lower diagram. Note that hole "A" is

located at the rounded part in the center of the altitude bar. Hole "A" is the "latitude

hole."

Attach two of the screws (one on either side of the adjuster bar) through the

appropriate altitude adjustment position hole and into hole A of the adjuster bar, but

do not tighten. Rotate the altitude adjuster bar around this pivot point until the

corresponding hole lines up. Consult the diagram to determine which hole of the

altitude adjuster bar should be used. Be very careful since the holes marked C and B

are very close to one another, as are the holes marked D and E. The incorrect hole

may appear to line up, however it will be slightly off. If you try to attach at the incorrect

hole, you may strip the threads of the altitude bar. The correct hole will orient the

adjuster to be roughly perpendicular to the axis once the axis is lowered into place.

Once you have located the correct hole, insert the remaining two screws, and lightly tighten so that you still have

some ability to wiggle the bar.

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.

10. 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 adjuster bar fixing screws.

11. 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.

12. Firmly tighten both polar axis pivot screws with the hex key.
