Note: East/West Filtering – In order to ensure the best

possible full-sky pointing accuracy, your computerized

mount automatically ﬁlters and chooses its initial

alignment stars so that the ﬁrst two alignment stars

are located on one side of the Meridian and any

calibration stars are on the opposite side of the

Meridian, as indicated by the “W” or “E” displayed in

the upper-right corner of the LCD. East/West ltering

can be changed simply by pressing the MENU button

at any time during the alignment process.

Tips for adding calibration stars:

• Although for casual observing it is not necessary to add

calibration stars, it is recommended that you add as many

as three calibration stars for optimal point accuracy.

• Choosing calibration stars that are near the celestial

equator offer the better results than stars near the

celestial poles.

• Although it is not necessary to use calibration stars if the

telescope mount has not been moved since its original

alignment/calibration, it may be necessary to recalibrate

the telescope if the optical tube has been removed for any

reason.

Note: Meridian – The Meridian is an imaginary line in the

sky that starts at the North celestial pole and ends at the

South celestial pole and passes through the zenith. If you are

facing south, the meridian starts from your Southern horizon

and passes directly overhead to the North celestial pole.

For safety purposes, the Sun will not be displayed in any of

the hand control’s customer object lists unless it is enabled

from the Utilities Menu. To allow the Sun to be displayed on

the hand control, do the following:

1. Press the BACK button until the display reads

“Advanced VX Ready”

2. Press the MENU button and use the Up and Down keys

to select the Utilities menu. Press ENTER.

3. Use the UP and Down keys to select Sun Menu and

press ENTER.

4. Press ENTER again to allow the Sun to appear on the

hand control display.

The Sun can be removed from the display by using the same

procedure as above.

Tip: To improve the telescope pointing accuracy, you can

use the Re-Align feature as described below.

Quick-Align

Quick-Align uses all the date and time information entered at

startup to align the telescope. However, instead of slewing to

the alignment stars for centering and alignment, the telescope

bypasses this step and simply models the sky based on the

information given. This will allow you to roughly slew to the

coordinates of bright objects like the Moon and planets and

provides the telescope with information needed to track

objects in any part of the sky (depending on accuracy of

polar alignment). Quick-Align is not meant to be used to

accurately locate small or faint deep-sky objects or to track

objects accurately for astroimaging.

To use Quick-Align, simply select Quick Align from the

alignment options and press ENTER. The telescope will

automatically use the entered date/time parameters to align

itself with the sky and display Alignment Successful.

Note: Once a Quick-Align has been done, you can use the

Re-alignment feature (see below) to improve your

telescope’s pointing accuracy.

Last Alignment

The Last Alignment method will automatically recall the last

stored index positions to continue using the alignment that

was saved when the telescope was last powered down.

This is a useful feature should your telescope accidentally

lose power or be powered down.

Note: Just like with Quick-Align, you can use the Re-alignment

feature (see below) to improve your telescope’s

pointing accuracy after using the Last Alignment

method. To maintain a more accurate alignment over

a series of observing sessions, use the Hibernate

feature described later in this chapter.

Re-Alignment

The mount has a re-alignment feature which allows you to

replace any of the original alignment stars with a new star or

celestial object. This can be useful in several situations:

• If you are observing over a period of a few hours, you may

notice that your original two alignment stars have drifted

towards the west considerably. (Remember that stars are

moving at a rate of 15° every hour). Aligning on a new star

that is in the eastern part of the sky will improve your pointing

accuracy, especially on objects in that part of the sky.
