How it works:

After the objective, light from the telescope enters the blocking filter (at

left), where wavelengths near H alpha are transmitted while the rest are

reflected back out. Red H alpha light then passes through the telecentric

barlow lens elements to achieve a slower focal ratio, more parallel light

beam. The Etalon passes a very narrow range of light wavelengths, but

it is sensitive to temperature and light angle. In the Quark, the Etalon is

heated to approximately 100-150° F to control the wa velength passed,

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

While not in use, we recommend that users store the optics with their

end caps on, in a climate controlled environment. The optical filter life

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

Do not touch the optical elements. While the exterior glass surface

coatings are durable, they are easily scratched. A few specks of dust will

have no effect on the quality of the image, and may be gently blown off

with a squeeze bulb. Do NOT use compressed air cans to blow dust off

any optical surfaces. Small amounts of residual 'film' will not affect visual

performance. Fingerprints, smudges and smears must be cleaned off.

Preferred cleaning method is to return the telescope to the DayStar

Filters laboratory for proper factory cleaning.

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

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

opened. Opening the optical filter assembly will void your warranty. The

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

"Qtip" with a pure acetone, methanol, or Isopropyl Alcohol (reagent

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

the glass surface. Stroke from the center of the aperture outward only.

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

better! The metal housing and other non optical parts are anodized

surfaces and can be cleaned with Windex.
