using the Azimuth Adjustment Knob and “◄” or
“►” button (The “▲” and “▼” buttons do not work
here)
. Press ENTER to confirm.
(3) The telescope will point to Star A again and
repeat above step until the error is minimum, or at
your decision. Press the BACK button to exit
alignment procedure.
10. Manual Operation of the Mount
: Now you can
observe astronomical objects using the arrow keys of
a Go2Nova
TM
hand controller. Flip the I/O switch on
the telescope mount to turn on the mount. Use
►,◄,▼ or ▲ buttons to point the telescope to the
desired object. Use the number keys to change the
slewing speed. Then press STOP/0 button to start
tracking.
11. Setup Controller:
The time and site information of the
observation location needs to be entered for precise
GOTO.
Turn the mount power on. Wait for controller lights on.
Press the MENU button. Move the cursor to “Set Up
Controller” and press ENTER. Select “Set Up Time
& Site” and press ENTER.
Enter the date and check if it is Daylight Saving Time
using arrow keys and number keys. Enter your time
zone (add or subtract 60 minutes per time zone) by
entering minutes “behind” UT or “ahead of” UT, such
as:
• Boston is 300 minutes “behind” UT
• Los Angeles is 480 minutes “behind” UT
• Rome is 60 minutes “ahead” of UT
• Sydney is 600 minutes “ahead” of UT
All the time zones in North America are “behind” UT.
You may also find your observation longitude and
latitude coordinate from your GPS navigator, a GPS
capable cell phone or from internet. “W/E” means
western/eastern hemisphere; “N/S” means
northern/southern hemisphere; “d” means degree; “m”
means minute; and “s” means second. Use number
keys and arrow keys to enter your location information.
Move the cursor to the end of the screen to select
Northern or Southern Hemisphere.
12. One Star Alignment:
Perform One Star Align to
correct the Zero Position discrepancy. To further
improve the GOTO accuracy, refer to the full manual
for more details.
13. Go to an Object:
The mount is now ready to GOTO
and tracking targets. Press MENU button, select
“Select and Slew” and press ENTER. Select a
category (ex. “planets, sun, moon”). Then select an
object (ex. “moon”). Then press ENTER. The
telescope will automatically slew to the object and
start tracking.
14. Sync to Target:
If the star is not in the center of the
eyepiece, one can use this function to center and
synchronize the object to improve the local GOTO
accuracy. Press MENU button and select “Sync. To
Target.” Press ENTER. Next use the arrow keys to
move object until it is centered in your eyepiece. Then
press ENTER again on the hand controller. A Select
and Slew has to be performed before “Sync to
Target” operation. This is most useful if you are
looking for some faint objects near a bright star.
“Sync to Target” is similar to “one star alignment”.
15. Identify Nearby Bright Objects:
After slewing to an
object using hand controller, a list of nearby bright
object(s) will be displayed by pressing the “?” button.
16. Adjust Gear Mesh Tension:
The Gear Switch
Locking Screws also serve as gear mesh tensing
adjusters. You may adjust R.A. and/or DEC gear
meshing tension by turn the Gear Switch Locking
Screws as needed.
