IMPORTANT IMPORTANT IMPORTANT IMPORTANT IMPORTANT: Read these instructions fully and carefully before installing encoders. This
instruction sheet gives the attachment points for the optical encoder kit supplied with Tele
Vue’s Sky Tour computer. These instructions also basically apply to other computer kits
designed for the Gibraltar mount.
Azimuth Encoder
IMPORTANT
IMPORTANT IMPORTANT IMPORTANT IMPORTANT: Remove the Gibraltar Mount Head Gibraltar Mount Head Gibraltar Mount Head Gibraltar Mount Head Gibraltar Mount Head from the tripod before installing the
azimuth encoder.
1) With the tripod upside-down, tray removed and legs spread, note the 2, #6-32 tapped
holes in the underside of the Tripod Head
Tripod Head Tripod Head Tripod Head Tripod Head. Lay the encoder assembly with the attached
metal strap onto the Tripod Head Tripod Head Tripod Head Tripod Head Tripod Head, making sure the electrical pins don't contact the metal
head. Thread the #6-32 socket head screws into the head, leaving them loose enough
so the encoder assembly can slide for positioning.
2) Turn the tripod right side-up and re-attach the triangular tray.
3) Gently lower the Gibraltar Mount Head Gibraltar Mount Head Gibraltar Mount Head Gibraltar Mount Head Gibraltar Mount Head into the Azimuth Bearing Hole Azimuth Bearing Hole Azimuth Bearing Hole Azimuth Bearing Hole Azimuth Bearing Hole until it is fully
seated. Expect some resistance when the Azimuth Bearing Shaft Azimuth Bearing Shaft Azimuth Bearing Shaft Azimuth Bearing Shaft Azimuth Bearing Shaft engages the Azimuth Azimuth Azimuth Azimuth Azimuth
Encoder Bushing Encoder Bushing Encoder Bushing Encoder Bushing Encoder Bushing. Reach under the Tripod Head Tripod Head Tripod Head Tripod Head Tripod Head and tighten the azimuth encoder
assembly.
Altitude Encoder
IMPORTANT
IMPORTANT IMPORTANT IMPORTANT IMPORTANT: Note which arm of the Mount Head Mount Head Mount Head Mount Head Mount Head has the Altitude Alignment Mark Altitude Alignment Mark Altitude Alignment Mark Altitude Alignment Mark Altitude Alignment Mark
(drilled mark straddling the Yoke Arm Yoke Arm Yoke Arm Yoke Arm Yoke Arm and Bearing Cover Disk Bearing Cover Disk Bearing Cover Disk Bearing Cover Disk Bearing Cover Disk, see drawing below).
NEVER loosen the 2 screws from this disk, or you will lose the accuracy of the alignment
mark.
1) Note the Yoke Arm
Yoke Arm Yoke Arm Yoke Arm Yoke Arm and Bearing Cover Disk Bearing Cover Disk Bearing Cover Disk Bearing Cover Disk Bearing Cover Disk without the alignment mark. The side of
this arm has 2, #6-32 tapped holes that accept an encoder assembly. (The Bearing Cover Bearing Cover Bearing Cover Bearing Cover Bearing Cover
Disk Disk Disk Disk Disk almost covers them) Remove the two screws holding this Bearing Cover Disk Bearing Cover Disk Bearing Cover Disk Bearing Cover Disk Bearing Cover Disk in place.
Wipe any excess grease from the exposed surfaces and save the parts for possible future
use.
2) Push the Altitude Encoder Shaft Altitude Encoder Shaft Altitude Encoder Shaft Altitude Encoder Shaft Altitude Encoder Shaft into the Encoder Shaft Encoder Shaft Encoder Shaft Encoder Shaft Encoder Shaft Hole Hole Hole Hole Hole in the center
of the Brass Bearing Brass Bearing Brass Bearing Brass Bearing Brass Bearing. Lock it to the bearing by tightening the Allen key
Encoder Shaft Set Screw Encoder Shaft Set Screw Encoder Shaft Set Screw Encoder Shaft Set Screw Encoder Shaft Set Screw located in the side of the Brass Bearing Brass Bearing Brass Bearing Brass Bearing Brass Bearing.
3) Next, place the bell shaped Encoder Housing Encoder Housing Encoder Housing Encoder Housing Encoder Housing over the altitude encoder. Securely
tighten one of the shorter #6-32 button head screws into the side of the Yoke Arm Yoke Arm Yoke Arm Yoke Arm Yoke Arm. To ensure
encoder accuracy, squeeze the sides of the Encoder Housing Encoder Housing Encoder Housing Encoder Housing Encoder Housing so that you feel it press
against the encoder body as you tighten the second button head screw to the Yoke Arm Yoke Arm Yoke Arm Yoke Arm Yoke Arm.
This will prevent the encoder body from moving within the housing while the shaft rotates.
Electrical Connectors
Plug the phone jacks into the receptacles, noting the longer wire connects to the
altitude encoder.
Getting Started With Your Computer
1) Mount the telescope within Gibraltar’s Cradle
Gibraltar’s Cradle Gibraltar’s Cradle Gibraltar’s Cradle Gibraltar’s Cradle and balance it using the
Gibraltar Mount instructions.
2) Turn the computer on. The Sky Tour will request “ALIGN MARK” (other
computers might say “level me”). Swing the Cradle
Cradle Cradle Cradle Cradle so that the two semi-circle
Alignment Marks Alignment Marks Alignment Marks Alignment Marks Alignment Marks come together to form a circle. (The mark was precision drilled
in a fixture with the cradle base carefully set 90° to the azimuth axis.) A low
power eyepiece such as a 32mm or 40mm Plössl used in reverse will make a
great magnifier to assist in aligning the semi-circles.
3) Follow your computer’s instructions for “STAR FIX” alignment to the night sky.
“I've found the computer a lot of fun and very educational even after 40 years
as an amateur who disdains the complexity of setting circles. It's great for locating objects,
learning the names of stars, and identifying objects. I hope you enjoy the Gibraltar mount
with our telescope and its computer capabilities. Please write me with your comments and
suggestions on all aspects of its operation and use.” - Al Nagler
