Daystar Quark H-alpha eyepiece - Chromosphere model. The first Hydrogen Alpha eyepiece side filter system for refractors from f/4 to f/9

This new, All-In-One design marries high quality components of a telecentric barlow, adapters, snouts and Daystar hydrogen alpha filter into one simple assembly. Through design efficiency and optimization, now users can enjoy the known high quality optics of DayStar at an affordable price.

The Dystar Quark is available in a choice of "prominence" or "chromosphere".

For use on refractors of F/4 to F/9, the user needn't worry about configurations. Just insert in your diagonal, add an eyepiece and view.

The patent pending QUARK contains a custom Daystar Instruments 4.2X telecentric barlow lens fully optimized in coatings and optical design specifically for the Hydrogen Alpha wavelength. This highly specialized telecentric lens offers superior field flatness.

Exact filter bandpass will vary based on final telescope application, so QUARK assemblies are qualified to show either prominence or surface (chromosphere).  No specific FWHM bandpass is designated.  Now observers can buy a filter based on their desired observing goals instead of their budget.  Choose prominences and surface (Chromosphere) detail. Both are available for the same low price!  

The fully optimized design eliminates the need for any adapters.  It's all combined in one lightweight eyepiece sized device. The new, compact design configuration eliminates unnecessary components, weight and associated costs. We even reduced power consumption, so the Quark can now operate all day off a small, palm-sized optional battery pack. Baffles have been added to increase contrast and AR coatings are optimized for the 656nm wavelength.

Daystar Quark uniformity standard

Due to the nature of the mineral mica crystals used, the Daystar pricing structure is tied to etalon uniformity. The Daystar Quantum products are offered in SE grade and PE grade uniformity. All Quark filters are warranted to meet or exceed the SE grade uniformity standard.

Due to scarcity and certification requirements, PE grade uniformity is reserved for the top-end Quantum PE product line.  

The uniformity grade of a filter is based on the uniformity in abundances of chemical composition (and subsequent index of refraction) within the natural mica crystal. Prices for the PE grade filters reflect the rarity of the required uniformity in homogeniety.

  •     STANDARD SE GRADE filters are specified as: Spectral uniformity: The mean peak wavelength of all 12 mm. dia. areas shall be within 0.5 Angstrom of the full aperture wavelength measurement. (In fractions of a wavelength of light, this accuracy is equal to 1/13,126 wave).
  •     PROFESSIONAL PE GRADE filters are fabricated and qualified to very high uniformity tolerances to the specification of Spectral uniformity: The mean peak wavelength of all 12 mm. dia. areas shall be within 0.05 Angstrom of the full aperture wavelength measurement. (In fractions of a wavelength of light, this accuracy is equal to 1/131,260 wave).

QUARK Filters share the Standard SE grade filter specifications, and are specified as: Spectral uniformity: The mean peak wavelength of all 12 mm. dia. areas shall be within 0.5 Angstrom of the full aperture wavelength measurement

Daystar 480 doublet refractor optical tube features 80 mm aperture, F/6 focal ratio, dual speed Caryford Hybrid focuser, aluminium hard case, 2" dieletric mirror diagonal.
