IMPORTANTIMPORTANT

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

IMPORTANTIMPORTANT

IMPORTANT: Remove the

Gibraltar Mount HeadGibraltar 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 HeadTripod Head

Tripod Head. Lay the encoder assembly with the attached

metal strap onto the

Tripod HeadTripod 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

NEVER loosen the 2 screws from this disk, or you will lose the accuracy of the alignment

mark.

1) Note the

Wipe any excess grease from the exposed surfaces and save the parts for possible future

tighten one of the shorter #6-32 button head screws into the side of the

encoder accuracy, squeeze the sides of the

against the encoder body as you tighten the second button head screw to the

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 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 so that the two semi-circle

Alignment MarksAlignment 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.”
