Congratulations on your purchase of a Quark Hydrogen Alpha "Eyepiece"
solar filter, designed specifically for compatibility with Schmidt Cassegrain,
Maksutov, and F/15 or greater Refractor telescopes.
manual before using the product.
To use the filter, plug in the included power supply. For SCT or Maks,
place a red or yellow glass off axis ERF (not included) over the front of
the telescope, and the included wedge adapter between the telescope
and the Quark, with the set screw on the wedge adapter pointing on the
same side as the off axis hole. For F/15 or greater refractors, do not
use the wedge adapter. 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 an Energy Rejection
Filter.
This can be a red or yellow glass ERF mounted in front of the
telescope.
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 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/15 to F/30 light.
  • Page 3 USAGE: The Combo 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 ENERGY REJECTION: Energy Rejection Filters reduce the heat load on your filter assembly by absorbing or reflecting UV and/or IR light and transmitting light in the visual spectrum. These filters are Red, Yellow, or clear glass with an IR and UV reflective coating. The ERF can also serve as an aperture mask to accomplish a straight angle of incidence for light entering the filter.

  • Page 5: How It Works

    SCHMIDT CASSEGRAIN TELESCOPES: SCT telescopes typically employ front mounted Energy Rejection Filter (ERF) with an off-axis opening reduced aperture. Full aperture glass ERF’s prohibitively expensive and daytime seeing quality limits resolution. By reducing the aperture, the focal ratio of your SCT will be increased from the native focal ratio to the preferred ~F/30 beam.
  • Page 6 '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 8 DayStar filters should heed daytime seeing. While many of these conditions are beyond our control, observing in an area with ideal conditions, without pavement in the direction of viewing, and on days with no high cirrus will offer best results.
  • Page 9 Another effect present in CCD imaging of monochrome light of Hydrogen Alpha is the interference pattern - or Newton's Rings. effect is similar to interference testing of an optical surface between two flat surfaces. The sensor and cover slip cause a small interferometer inside the camera and cause a Newton's Ring moire' pattern.
  • Page 10 recombination in a computer. 12 bit or 16 bit cameras enable capturing these features in the same exposure, simplifying the image processing. Focal reducers: Because of the long effective focal length at the output of the Quark, the image scale will be quite large and small (1/2” or below) image sensors will only capture a fraction of the whole solar disk in one frame.
  • Page 11 0.4Å, where prominence structure is reduced due to high velocity and subsequent wing shift. Filaments appear as large, dark eyebrows across the surface of the Sun. With a brightness of about 10% of the disk scattering, they appear dark on the surface, but on the limb, show as a prominence. Active Region Filaments (ARF) differ from Quiescent Region Filaments (QRF).
  • Page 12 Inside an active region, where sunspots are originally linked by a FTA, a shear boundary forms. Field Transition Arches are different from filaments in that they are thin and not very dark. The FTA usually has plage or granular structure underneath. Plages: Most of the active region area is occupied by plage.

    Emerging Flux Regions: An area on where magnetic dipole, or "flux tube" surfacing on the disk, eventually producing a bipolar sunspot group. Each pole of an EFR is often marked by pores or small developing sunspots. Surges or even small solar flares can sometimes occur in EFRs.

    Yellow, never goes green LED indication: If after 20 minutes of the same knob position setting the LED has not turned green, the ambient temperature may be too hot or too cold for the Quark to regulate the temperature. However, the filter may still be usable while slightly mistuned and performance may not be affected.
