DAYSTAR FILTERS
Congratulations on your purchase of a Quark Calcium "Eyepiece" solar filter,
designed specifically for compatibility with F/7 or greater Refractor
telescopes. Please read this manual before using the product.
To use the filter, plug in the included power supply. Then insert the
Quark and insert an eyepiece or camera in the rear of the Quark. Turn
the knob to point straight away from the light. When the light turns
green in about 5-15 minutes your viewing experience can begin.
To prevent damage, we strongly recommend using a UV/IR cut filter over
80mm of aperture.
Warnings:
Do not disassemble the filter, the blocking element is separated from the
etalon and the complete assembly must be used together for safe viewing.
Do not power the filter from a computer or cell phone charger as the Quark
requires a high current power supply (> 1.5A) for operation.

  • Page 1 DAYSTAR FILTERS CALCIUM QUARK Congratulations on your purchase of a Quark Calcium “Eyepiece” solar filter, designed specifically for compatibility with F/7 or greater Refractor telescopes. Please read this manual before using the product. To use the filter, plug in the included power supply. Then insert the Quark and insert an eyepiece or camera in the rear of the Quark.

  • Page 2: Cautions And Warnings

    A few very important points that owners and operators must understand: • DayStar Filters are interference filters. If light reaches a DayStar Filter at an angle, it will cause wavelength wing shift. For our application on a telescope, DayStar owners need F/7 to F/30 light.
  • Page 3 USAGE: The Calcium 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.
  • Page 4 Note that Red and Yellow glass ERFs are NOT compatible with the Calcium Quark as they do not pass the Calcium wavelength, by the nature of colored glass. Please note, a Herschel Wedge or white light filter cannot be used with the Quark.

  • Page 5: How It Works

    Hinode spacecraft and Dutch Open Telescope have further popularized the H line in recent years. For all of these reasons, we are offering the Calcium Quark in H line. How it works: Light from the telescope enters the blocking filter, where wavelengths near Calcium H are transmitted while the rest are reflected back out.

  • Page 6: Care And Cleaning

    '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.
  • Page 7 Eyepiece Selection: Daystar Recommends Tele Vue Plossl series eyepieces of 12mm to 32mm. Remember that at long focal ratios, a high powered eyepiece can exceed Dawes' limit. Observers will find best results with an eyepiece which is 12mm or greater to avoid this. Eyepieces of higher power will result in a fuzzy disk without the ability to focus well.
  • Page 8 - A jet-stream moving overhead can also hurt seeing conditions even on a clear day. DayStar Filters are high power viewing platforms and this high resolution can be susceptible to seeing issues. Solar Observers using high powered, high resolution telescopes and DayStar filters should heed daytime seeing.
  • Page 9 Please advised, however, that due to the nature monochromatic light and its effects on a CCD camera, certain negative effects likely occur. The DSLR imager must aware that most camera manufacturers (Canon and Nikon) use an IR blocking filter which greatly reduces the transmission of Hydrogen Alpha light.
  • Page 10 Exposure time: Imaging solar vs. nighttime astrophotography is very different. Dark sky imaging requires long exposure times to capture enough light. Solar imaging offers ample light, so exposures should be very short. Plus, fluctuations in seeing dictate that short <1/10 second frame rates will be better, as seeing cells move quickly to distort the image and can come and go during a long exposure.
  • Page 11 Features of the Sun in Calcium: By observing the sun with a narrow bandpass filter tuned to 3968.5Å, we can observe the behavior of the Sun's Chromosphere. chromosphere is like a shell of around Sun's photosphere, always moving and changing. The chromosphere's structure behaves differently in active regions than quiet areas, where magnetic field lines are stronger.
  • Page 12 On the limb you may see prominences, a detail of the chromosphere projected against the dark black contrast of space. Prominences are typically much fainter Calcium than Hydrogen Alpha. Filaments are Prominences seen on the disk of the Sun and are a challenging observation at Calcium. Active Regions concentration of magnetic...

  • Page 13: Troubleshooting

    Troubleshooting: Blank, featureless disk: Ensure power is applied and LED is green. Try moving focus in and out significantly, up to three inches (76mm). It may be necessary to remove your diagonal, and view straight through. Make sure a 12 to 32mm eyepiece (not included) is installed. Ensure knob is pointing straight away from the power jack.

  • Page 14: Specifications

    Red indication can also mean an electrical fault in the Quark electronics. If power source changes do not resolve the red indication, please return the Quark to DayStar for inspection and repair. Specifications: Wavelength: 3968.5Å (H line) Tuning knob: Wing shift +/- 0.5Å in 0.1Å increments. FWHM: 5Å.
