Autoguide Rate –

Allows the user to set an autoguide rate as a percentage of sidereal rate. This is helpful

hen calibrating your telescope to a CCD autoguider for long exposure photography.

Mount Settings-

Once the mount settings have been calibrated (see Utilities section below) the values are

stored and displayed in the hand control. It is not recommended that the calibration valu

ach setting can be changed if necessary to improve the performance of the telescope.

•

Cone Value – This is the cone error value set when calibration stars are added

•

DEC Switch - This is the declination index error value set when calibrations stars are added.

•

RA Switch - This is the R.A. index error value set when Utilities / Calibrate Mount / R.A. Switch

is carried out. This procedure records the offset of the RA index switch from the Meridian.

tility Features

Scrolling through the MENU (9) options will also provide access to several advanced utility functions within

e CGE Series telescopes such as; Calibrate Goto, Polar Alignment, Hibernate as well as many others.

Calibrate Mount

- In order to optimize the performance and pointing accuracy of the CGE mount, the moun

has built-in calibration routines allowing it to compensate for mechanical variat

equatorial mount. Each calibration is completely automatic and in most cases

only needs to be performed once. It is highly recommend

inutes to go through the mount calibration procedures.

•

R.A. Switch Calibration - This procedure records the offset of

RA index switch from the meridian. To perform an RA Switch

Calibration, the mount must be polar aligned and a t

must have been performed with calibration stars.

•

Calibrating the RA switch will improve the pointing accuracy to

the initial alignment stars when the mount has been polar aligned

To successfully calibrate the R.A. switch of your telescope, you should

llow a complete alignment process which includes the following:

Complete a Two-Star alignment adding three calibration stars at

the end. (See Alignment Procedures earlier in this section).

Use the Polar Align Utility feature to polar align your telescope as

described later in this section.

Once polar aligned you must re-align your telescope using the

Two-Star alignment method and adding calibration star as an

option.

Finally, use the Utility/Calibrate Mount/ R.A. Switch feature to

properly calibrate the R.A. axis of the mount.

•

GoTo Calibration – Goto Calibration is a useful tool when attaching

heavy visual or photographic accessories to the telescope. Goto

Calibration calculates the amount of distance and time it takes for the

mount to complete its final slow goto when slewing to an object.

Changing the balance of the telescope can prolong the time it takes to

complete the final slew. Goto Calibration takes into account any slight

imbalances and changes the final goto distance to compensate.

Home Position –

The telescope's "home" position is a user-definable position that is used to store the

telescope when not in use. The home position is useful when storing the telescope in a permanent observatory

facility. By default the Home position is the same as the switch position used when aligning the mount. To set

the Home position for your mount simply use the arrow buttons on the hand control to move the telescope

ount to the desired position. Select the Set option and press Enter.
