without the Quark, and ample additional backfocus is available.

The filter mu st be plu gged in usi ng th e su pplied power supply. The

etalon cavity is precision h eated to regulate the wave length of the filter

output.

Any other US B power source you wi sh to use m ust be rated fo r at least

1.5 amp s at 5 volts. Co mputer USB ports and cel l phon e chargers d o

not normally support this much power.

knob counter clockwise to lower the wavelength towards the blue by u p

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.

Tuning i s required on tele scopes with "droop" of th e focu ser, be cause

even very sli ght tilts will effectivel y lower th e ce nter wavelengt h of the
