When transporting the telescope, take care not to bump or drop the instrument; this type of
abuse can damage the optics or affect the GOTO tracking accuracy.
7.3. Troubleshooting
The following suggestions may be helpful with operation of the Solar 60
TM
telescope.
The power indicator light on the mount does not come on or there is no response when
pressing hand controller’s arrow keys:
(1) Verify that the power switch on the mount is in the ON position.
(2) Verify that the hand controller cord is firmly connected to the HBX port on the mount, or
switch the cord to the other HBX port.
(3) Check the power source, which include:
Using the battery? Are the batteries installed correctly? Are the batteries fresh? How
long have they been used? (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.
The mount is turned on and hand control is displaying the information screen. When an
arrow key is placed, the motor is running but the mount is not moving:
Please check the slew speed on the LCD screen. Press the SPEED key to change it to MAX
and try it again.
Cannot seem to focus (No image appears in the eyepiece):
(1) Confirm that the dust cap has been removed from the telescope.
(2) Make sure the glass solar filter is taken off if observing any other object except Sun.
(3) Keep turning the focus knob slowly in one direction.
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:
