Troubleshooting:
Blank, featureless disk:
Ensure power is applied and LED is green.
Try moving focus in and out significantly, up to three inches (76mm). It
may be necessary to remove your diagonal, and view straight through.
Make sure a 12 to 32mm eyepiece (not included) is installed.
Ensure knob is pointing straight away from the power jack.
Check for droop, all connections between telescope and Quark must be
tight and square.
Dim, dark view:
Ensure UV/IR cut filter passes 397nm with a good transmission.
Wear a hood to block ambient light.
Reconfigure telescope to a faster focal ratio.
Poor contrast:
Check that optical surfaces are clean. Dust specks do not affect the
view, check for smudges such as oil from fingerprints.
Try adjusting wing shift knob up 3-4 clicks clockwise past center and
wait 5-15 minutes. If that does not improve the view, try down 3-4 clicks below
center and wait 5-15minutes.
Atmospheric seeing or transparency may be poor, try again later.
Blurry image:
Blurry views are typically due to poor seeing. Poor seeing can be
caused by the presence of heat waves from concrete, asphalt, or machinery.
Weather effects like the jet stream can also cause blurring. Try moving to a
different location or else observe on a day when weather conditions are
improved.
Yellow LED indication:
Your filter is adjusting to the wavelength chosen by the knob. Wait
approximately 5-15 minutes for the temperature to adjust and then light should
turn green, indicating that the filter has settled to its required temperature and is
on band for viewing.
Yellow, never goes green LED indication:
If after 20 minutes of the same knob position setting the LED has not
turned green, the ambient temperature may be too hot or too cold for the Quark
to regulate the temperature. However, the filter may still be usable while slightly
mistuned and performance may not be affected.
This can also occur if plugged into a computer USB port, which causes
the filter heater to reduce its current draw. Use the supplied power adapter or a
source rated for 1.5 amps, not a data USB port.
Red LED indication:
This usually indicates that the Quark is not receiving enough voltage. If
powered by battery, recharge the battery. Make sure to use the supplied AC/DC
wall adapter, as cell phone chargers and PC USB ports do not have enough
current capability for the Quark.
