  • Daystar Combo Quark Prominence Solar Filter

    The Daystar Combo Quark Prominence Solar Filter transforms long focal ratio telescopes, from f/15 to f/30, into dedicated hydrogen-alpha solar instruments in a single, eyepiece-style unit. This all-in-one assembly integrates a Fabry Perot etalon with AR coatings optimized for the 656nm wavelength and is powered by a standard 5V 1.5amp USB source, eliminating the need for complex adapter configurations.

    An All-In-One Hydrogen-Alpha Filter for f/15-f/30 Telescopes

    Daystar's Combo Quark simplifies hydrogen-alpha solar observing by integrating the filter, adapters, and snouts into a single, lightweight device. Designed for telescopes with focal ratios of f/15 or longer, such as Schmidt-Cassegrains, Maksutovs, and classic long-tube refractors, it operates just like an eyepiece. Simply insert the Quark into your diagonal, add your preferred eyepiece to the brass compression ring, and you are ready to view.

    Optimized for Prominences: Contrast-Enhancing Baffles and 656nm Coatings

    This model is specifically qualified to reveal solar prominences—the dramatic eruptions of plasma seen along the limb of the Sun. To maximize image contrast, the Quark features internal baffles and anti-reflection coatings precisely tuned for the 656nm hydrogen-alpha wavelength. This specialized design ensures that faint, eruptive details stand out clearly against the blackness of space.

    5V USB Power for All-Day Solar Sessions

    The internal Fabry Perot etalon requires precise heating to stay on-band, which is managed by a low-draw 5V, 1.5amp USB power system. This modern power solution allows the Quark to operate from various sources, including the included 90-240VAC wall adapter with international plugs or an optional palm-sized battery pack for field use. The efficient design enables continuous, all-day operation without significant power consumption.

    Critical Safety Requirements for SCT and Maksutov Telescopes

    Safe solar observing is paramount. When using the Combo Quark with a Schmidt-Cassegrain or Maksutov-Cassegrain telescope, you must use an off-axis Energy Rejection Filter (ERF). Using this filter with a full-aperture SCT or Mak without an ERF will concentrate excessive heat and light, resulting in permanent damage to your telescope's secondary mirror. The required ERF is sold separately and must be matched to your specific telescope model.

    Combo Quark: Prominence vs. Chromosphere Models

    Daystar offers the Combo Quark in two distinct versions tailored to different observing goals. While the Chromosphere model excels at revealing fine surface texture like filaments and plages, this Prominence model is specifically qualified to maximize contrast for outbursts and loops extending beyond the solar disk. This allows you to choose a filter based on your primary interest rather than a specific bandpass, as the final performance is a function of your telescope's focal ratio.

  • How do I use the Daystar Combo Quark Prominence filter with my 8" f/10 SCT?

    You must first install an off-axis Energy Rejection Filter (ERF), sold separately, over the front of your telescope. Once the ERF is securely in place, insert the Combo Quark into your diagonal, then place a standard eyepiece into the back of the Quark. The Quark's internal optics will bring your telescope's focal ratio into the required f/15-f/30 range for proper operation.

    What can I expect to see with the Daystar Combo Quark Prominence and a long f/15 refractor?

    With an f/15 refractor, this filter is perfectly suited for high-contrast views of the solar limb. You can expect to see eruptive prominences, detached filaments, and delicate loops set against a dark background. Surface detail like granulation and plages will be visible but less pronounced than with the companion Chromosphere model.

    What kind of power supply does the Daystar Combo Quark Prominence filter need?

    The Daystar Combo Quark Prominence filter uses a standard USB 5V, 1.5amp power source. It includes a 90-240VAC wall adapter with international plugs. For portability, it can also be powered by a small, optional USB battery pack, allowing for extended observing sessions in the field.

    Do I need any special adapters for the Daystar Combo Quark Prominence filter?

    No, the Daystar Combo Quark Prominence is an all-in-one design that fits directly into a standard 1.25" or 2" diagonal. The only essential accessory is an off-axis ERF for SCT and Maksutov telescopes, which is a critical safety component, not a mechanical adapter.

    What is the difference between the Daystar Combo Quark Prominence and Chromosphere models?

    The two models are tuned for different solar features:

    • Prominence Model (this one): Optimized for high-contrast views of features on the Sun's edge (limb), like flares and eruptions.
    • Chromosphere Model: Optimized for viewing details on the Sun's surface (disk), such as filaments, plages, and granulation.

    Why doesn't the Daystar Combo Quark Prominence have a specific bandpass rating?

    The final filter bandpass of the Daystar Combo Quark Prominence is dependent on the focal ratio of the telescope it's used with. Instead of providing a fixed FWHM number that can be misleading, Daystar qualifies each unit to perform best for a specific observational goal—in this case, viewing solar prominences.
