Tracking Rate

View Time-Site

- Displays the current time and longitude/latitude downloaded from the optional CN-16 GPS

receiver. It will also display other relevant time-site information like time zone, daylight saving and local

sidereal time. Local sidereal time (LST) is useful for knowing the Right Ascension of celestial objects that

located on the Meridian at that time. View Time-Site will always display the last saved time and location entere

while it is

linking with the GPS. Once current information has been received, it will update the displayed

inform ion. If GPS is switched off or not present, the hand control will only display the last saved time and

locatio

ill continually track a celestial object as it moves across the night sky.

The tracking rate can be changed depending on what type of object is being

observed

Sidereal

This rate compensates for the rotation of the Earth by moving the

telescope at the same rate as the rotation of the Earth, but in the

pposite direction. When the telescope is polar aligned, this can

be accomplished by moving the telescope in right ascension only

Lunar

Used for tracking the moon when observing the lunar landscape.

Solar

sed for tracking the Sun when solar observing with the proper

filter.

Your telescope can store over 100 different user defined objects in its memory (99

sky objects and 9 land objects). The objects can be daytime land objects or an

interesting celestial

object that you discover that is not included in the regular

database. There are several ways to save an object to memory depending on what

type of object it is:

To go to any of the user defined objects stored in the database, scroll down to either

GoTo Sky Obj or Goto Land Obj and enter

wish to select and press ENTER. The telescope will automatically retrieve and

display the coordinates before slewing to the object.

Your telescope stores celestial objects to its database by saving its right ascension

and declination in the sky. This way the same object can be found each time the

telescope is aligned. Once a desired object is centered in the eyepiece, simply

scroll to the "Save Sky Obj" c

you to enter a number between 1-99 to identify the object. Press ENTER again to

save this object to the database.

This feature allows you to create your own custom tour of database objects by

allowing you to record the current position of

the object by selecting it from any one of the database catalogs. These objects then

can be accessed by selecting GoTo Sky Object.

You can also store a specific set of coordinates for an object just by entering the

R.A. and declination for that obje

and press ENTER. The display will then ask you to enter first the R.A. and then the

declination of the desired object.

The telescope can also be used as a spotting scope on terrestrial objects. Fixed land

objects can be stored by saving their altitude and azimuth relative to the location of

the telescope at the time of observing. Since these objects are relative to the

location of the telescope, they are only valid for that exact location. To save land

objects, once again center the desired object in the eyepiece. Scroll down to the

"Save Land Obj" c

enter a number between 1-9 to identify the object. Press ENTER again to save this

object to the database.
