How it works:
Light from the telescope enters the blocking filter (at left), where
wavelengths near Magnesium are transmitted while the rest are reflected
back out. Yellow Magnesium 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 wavelength passed,
and the telecentric barlow controls the angle of light entering the Etalon.
Care and cleaning:
While not in use, we recommend that users store the Quark with its 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 internal, optical elements of the filter assembly. 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 Quark to the DayStar Filters laboratory for proper 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 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.
