USAGE:
The Combo Quark has a standard eyepiece snout so that it can be
inserted directly into the eyepiece drawtube.
The filter must be plugged in using the supplied power supply. The
etalon cavity is precision heated to regulate the wavelength of the filter
output.
Any other USB power source you wish to use must be rated for at least
1.5 amps at 5 volts. Computer USB ports and cell phone chargers do
not normally support this much power.
After letting the filter come up to temperature and settle, the light will turn
green and viewing can begin.
Because the Quark requires about 67mm of additional backfocus (99mm
when used with the wedge adapter), you will need to dial the focus knob
quite significantly.
Knob tuning:
If the image lacks contrast, you may need to adjust the center
wavelength of the filter.
A knob is provided to adjust the center wavelength of the filter. Turn the
knob counter clockwise to lower the wavelength towards the blue by up
to 0.5Å. Turn clockwise to raise the wavelength towards the red by up to
0.5Å. Each click of the knob is 0.1Å.
Additional tuning can be performed, just keep in mind that after every
adjustment of the knob the filter must settle in temperature for
approximately 5-10 minutes before your change becomes effective.
Tuning can also be used to observe Doppler shifted features moving
towards or away from you. A feature moving towards you will be brighter
in blue (counterclockwise) wing shift, away from you will be reddened
(clockwise knob tuning).
