the RATE button, and then choose a number between 0 
(slowest) and 9 (fastest). You may find that Rate 4 is best 
for centering the object in the EZ Finder, while Rate 3 or 
less is best for centering in the eyepiece view. When the 
star is centered in the eyepiece, press ENTER.

5.  The hand controller will now generate a list of bright stars 

to choose as your second alignment star. Scroll through 
the list using the Scroll keys and refer to the appropriate 
star chart in the back of this manual to choose a second 
alignment star. Ideally, you want this star to be about 60 
degrees (i.e., about six fist-widths held at arm’s length) 
away from the first alignment star in azimuth, and pref-
erably at roughly the same altitude. The more distance 
between the two alignment stars, the better accuracy the 
alignment will produce. 
Once you’ve selected the second 
alignment star, press ENTER. The mount will now auto-
matically slew to the selected star, which should land in 
or near the field of view of the EZ Finder II. When it stops 
slewing you’ll hear a beep, then the hand controller will 
instruct you to use the directional buttons to center the star 
in the eyepiece. After you’ve done that, press ENTER.

The message “Alignment Successful” should display on the 
LCD. You may now use the hand controller to locate objects 
to view. At this time it is recommended that you switch to the 
low-power DeepView 2" eyepiece for acquiring targets using 
the GoTo system.
If the message “Alignment Failed” displays, it usually means 
the star positions do not correspond with the location and 
date/time information input during setup. Please check your 
user input settings before starting again.
NOTE: To ensure the accuracy of the star alignment, make 
sure to end the movement of the telescope with the UP 

or RIGHT directional button when centering the object in 
the eyepiece view.

NOTE: The hand controller will beep when the telescope 
has finished slewing to an object. Do not try to adjust the 
telescope position further before you hear the beep. The 
hand controller will only respond to the ESC key while 
slewing.

Two-Star Alignment

The standard two-star alignment is suggested if you have a 
star chart handy or are able to identify two bright stars visible 
in the night sky. To perform the two-star alignment, you follow 
the same steps described for the Brightest Star alignment, 
except that the hand controller will not prompt you to select a 
directional region for a bright star. Instead, you’ll be presented 
with a list of stars available in your current sky to choose from, 
for each of the two alignment stars.
Use the supplied 12.5mm Illuminated Plössl to ensure accu-
rate centering of your alignment objects. Refer to the appro-
priate star chart in the back of this manual for help in locating 
a specific star.
NOTE: When the power is on, you may choose to adjust 
the telescope electronically by using the hand control or 
manually by pushing the tube with your hand. The tele-
scope will calculate the coordinates accordingly and dis-
play the information correctly on the hand controller.

NOTE: The hand control’s backlit display will become 
dimmer and the button Illumination will turn off if left idle 
for 30 seconds. Pressing any button will re-illuminate the 
display.

NOTE: After doing a successful star alignment, the infor-
mation is stored in the hand controller even after the 
power has been turned off. You will only need to perform 
the star alignment once as long as these two criteria are 
met: 1. The telescope is moved to its Home position, i.e., 
the telescope is “parked” (Choose Menu > Utility Func. 
> Park Scope > Home position) before turning off the 
power, and 2. The telescope setup, including the mount, 
has not been moved. Changing accessories shouldn’t 
upset the alignment as long as it is done carefully. When 
the hand controller is turned on for the next session, 
make sure to choose YES when prompted whether to 
start from the Home position. The time entered during 
initial setup should be based on the same source as last 
time. For example, if you enter the time from your watch 
for this observing session, the time you enter next ses-
sion should also be read from your watch.
