How it works:

Light fro m t he tele scope enters th e blo cking filter

(at left),

where

wavelengths near H alph a are tran smitted whil e the re st are reflected

back out. Red H alpha light then p asses through the tele centric barlow

lens elem ents to achieve a sl ower fo cal ratio, m ore parallel lig ht beam.

The Etalon p asses a very narrow rang e of light wavelength s, but it is

sensitive to t emperature and lig ht an gle. In the

Quark, the Etalon is

heated to a pproximately 100-150°F to co ntrol the wavelength passed,

and the telecentric barlow controls the angle of light entering the Etalon.

While not in use, we re commend that users store the Qua rk with its end

caps on, in a climate controlled e

nvironment. The optical filter life

expectancy is extended up to 2-3 times by climate controlled storage.

Do n ot tou ch the internal, optical elements of the filter a ssembly. While

the exterio r glass

surface coatings a re d urable, they are ea

sily

scratched. A few specks of dust will have no effect on the quality of th e

image, a nd may be g ently blown off with a sque eze bulb. Do NOT u se

compressed air can s to

blow dust off any optical

surfa ces. S mall

amounts of residual 'film' will not affect visual performance. Fingerprints,

smudges and smears must be cleaned off. Preferred cleaning met hod is

to return the Quark to the DayStar Filters la boratory for prope r factory

cleaning.

Do not unscrew, open or separate your Quark filter assembly. The optical

elements are held under pressure by design and will become damaged if

opened. Opening the opti cal filter asse mbly will void your wa rranty. The

safest cleaning method i s to moisten a very soft, lint-free tissue, cloth or

"Qtip" with a pure acetone, methan ol, or Iso propyl Alcohol (reagent

grade) and gently whisk away the stain. Do not apply solutions directly to

the glass surface. Stroke from the center of the ape rture o utward only.

After each cleaning stroke, use a fresh applicator. The fewer strokes, the

better! The metal hou sing and othe r non optical parts are a nodized

surfaces and can be cleaned with Windex.
