Congratulations on your purchase of a Quark Magnesium "Eyepiece"
solar filter. Please read this manual before using the product.
To use the filter, plug in the included power supply, then place the
Quark after your telescope's diagonal and insert an eyepiece or
camera in the rear of the filter. Turn the knob to point straight away
from the LED light.
minutes your viewing experience can begin.
To prevent damage, we recommend using an Energy Rejection Filter on
telescopes of 80mm aperture or more, or when tracking the Sun for long
periods. This can be a UV/IR cut filter mounted before the diagonal, or a
full aperture 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 1 DAYSTAR FILTERS MAGNESIUM QUARK Congratulations on your purchase of a Quark Magnesium “Eyepiece” solar filter. Please read this manual before using the product. To use the filter, plug in the included power supply, then place the Quark after your telescope’s diagonal and insert an eyepiece or camera in the rear of the filter.

  • Page 2: Cautions And Warnings

    A few very important points that owners and operators must understand: • DayStar filters are rear-mounted and can be applied to a choice of telescopes if applied properly. If application is incorrect, the filter will not perform as specified. •...
  • Page 3 USAGE: The Quark is designed for use on F/4 to F/9 refractors. Combined with an integrated 4.3x telecentric barlow, this results in a F/17 to F/38 final image respectively, to provide the best performance from your filter. Because of the included barlow, images will appear 4x larger than without the Quark, and ample additional backfocus is available.
  • Page 4 Magnesium wavelength and cannot used with Magnesium Quark. Please note, a Herschel Wedge or white light filter cannot be used with the Quark. These filters pass very little light by design and so will...

  • Page 5: How It Works

    '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 6 Eyepiece Selection: Daystar Recommends Tele Vue Plossl series eyepieces of 25mm, 32mm, and 40mm. Remember that at F/30, a high powered eyepiece can exceed Dawes' limit. Observers will find best results with an eyepiece which is 32mm or greater to avoid this. Eyepieces of higher power will result in a fuzzy disk without the ability to focus well.
  • Page 7 - 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 8 Solar Imaging Tips: Daystar recommends MONOCHROME imaging whenever possible for best results. The recent availability of CCD cameras and DSLR cameras has offered a simple opportunity solar observers to image the Sun with a Digital SLR camera. Please advised, however, that due to the nature of monochromatic light and its effects on a CCD camera, certain negative effects are likely to occur.
  • Page 9 Lucky Imaging: Virtually all solar imaging can benefit from the technique of Lucky Imaging, where a high speed camera is used to capture hundreds or thousands of frames in a short time span. Then special software can be used to select and stack just the frames least affected by atmospheric seeing.
  • Page 10 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. Large pixel sizes (9 microns and above) will enable a larger field of view.
  • Page 11 Magnesium versus Hydrogen: The Magnesium I “b-line” triplet is of interest for plasma physics studies of the sun’s low atmosphere between 600km and 900km. The line offers insight into distinction between isotrophic microturbulent and vertical macroturbulence, the latter being a means of accounting for large-scale motions such as granulation and the five-minute oscillation.
  • Page 12 Features of the Sun in Magnesium: Active Regions concentration of magnetic acitivity with several types of features contained in a close area. Sunspots are concentrations of magnetic flux that appear as dark spots their colder temperatures. Sunspots last from days to weeks, and change in quantity with the 11 year solar cycle.

  • Page 13: Troubleshooting

    Troubleshooting: Blank, featureless disk: Thin clouds or haze may be present, try again later. Check solar activity, no sunspots may be present. Try moving focus in and out by 1-2 inches (2-5cm). Ensure Quark is installed AFTER diagonal. Make sure a 25 to 40mm eyepiece (not included) is installed. Ensure knob is pointing straight away from the power jack.
