iOptron 8503 Telescope User Manual

(frequent slew and GOTO will deplete
battery power very quickly)
Using AC or DC adapter? Check the
plugs to the mount and to the power
outlet.
Using extension cord? Make sure the
cord is in good condition. Power drop
along the extension cord was known to
cause the problem. Also check all the
plugs and connections.
4. If the telescope does not respond to
commands, set the power switch to OFF
and then back to ON.
5. If the telescope does not slew after
power is applied or if the motor quits or
stalls, verify that there are no physical
obstructions that would impede
telescope movement.
Cannot seem to focus (No image
appears in the eyepiece):
1. Confirm that the dust cap has been
removed from the telescope.
2. Keep turning the focus knob. Your
telescope has a fine focusing
mechanism which allows you to focus
an image very precisely. However, this
means that you may have to rotate the
focus knob 20 to 40 complete turns to
achieve focus, particularly the first time
you use your telescope. After that, fewer
turns will be needed.
Images through the eyepiece appear
unfocused or distorted:
1. The magnification used may be too high
for the seeing conditions. Back off to a
lower power eyepiece.
2. If inside a warm house or building, move
outside. Interior air conditions may
distort terrestrial (land) or celestial
images, making it difficult, if not
impossible, to obtain a sharp focus. For
optimal viewing, use the telescope
outside in the open air instead of
observing through an open or closed
window or screen.
3. If viewing a land object on a warm day,
heat waves distort the image.
4. The optics within the telescope need
time to adjust to the outside ambient
temperature to provide the sharpest
image. To "cool down" the optics, set
the telescope outside for 10 to 15
minutes before observing begins.
Error Message:
“Warning! Motor driver overloaded.”
1. Check the hand controller cord. Unplug
it and re-plug into, or plug it into another
HBX port.
2. Check the power source.
The telescope does not GOTO the
right object, or the alignment is
always wrong:
1. Leveling (very important)
2. Site information (minutes ahead or
behind UT, DST).
3. Check the power source.
6.4. iOptron Customer Service
If you have a question concerning your
telescope, contact the iOptron Customer
Service Department. Customer Service
hours are 9:00 AM to 5:00 PM, Easter Time,
Monday through Friday. In the unlikely
event that the telescope requires factory
servicing or repairs, write or call the iOptron
Customer Service Department first, before
returning the telescope to the factory, giving
full particulars as to the nature of the
problem, as well as your name, address,
and daytime telephone number. The great
majority of servicing issues can be resolved
by telephone, avoiding return of the
telescope to the factory.
It is also strongly suggested to send your
technical questions to upport@ioptron.com.
