Just insert in your diagonal, add an eyepiece and view. Through design efficiency and optimization, now users can enjoy the known high quality optics of DayStar at an affordable price.įor use on refractors of F/4 to F/8*, the user needn't worry about configurations. 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. The Prominence version has a bandpass of 0.8 - 0.6 Å, which will deliver bright, high-contrast views of prominences against a jet black sky. The Chromosphere version features a bandpass between 0.5 - 0.3Å (depending on your telescope's f-ratio), making it the perfect choice for viewing surface detail, although prominences will still be visible. The Quark is available in either Prominence or Chromosphere versions, depending on your goals. The UV/IR-cut filter must be the first optical element to receive concentrated light.įor telescopes which do not fit the above specifications, you must purchase a DayStar energy rejection filter to fit your particular telescope. Do not use a UV/IR-cut filter with oil-spaced objectives or any telescope with an integrated field flattener or Petzval lens. For refractors under 120mm of aperture, a screw-in UV/IR-cut filter can be used if placed in front of the telescope diagonal. To prevent damage to your telescope, the Quark must be used with an appropriate energy rejection filter (sold separately). The DayStar Instruments Quark Hydrogen-alpha Eyepiece is a revolution in Solar observation and imaging, allowing users to experience incredible views with their telescope of choice for a fraction of the cost of competing, purpose-built Solar telescopes.Ĭlick here for a tutorial on Solar photography with DayStar H-alpha filters and Player One cameras!
