Through design efficiency and optimization, now users can enjoy the known high quality optics of DayStar* at an affordable price. Quark* is available in a choice of \"prominence\" or \"chromosphere\". 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 for WIDER prominences with a little surface or MORE surface contrast (Chromosphere) and narrower prominences. Both are available for the same low price!\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eFor use on SCTs, Maks, or refractors of F\/15 to F\/30. The user needn't worry about configurations. Just insert Quark in your diagonal, add an eyepiece and view.\u003c\/li\u003e\n\u003cli\u003eSCT and Mak users need to purchase an Energy Rejection Filter specific to their telescope for safe operation.\u003c\/li\u003e\n\u003cli\u003eSCT owners must employ a front mount, off-axis, aperture reduced Energy Rejection Filter (ERF) in order to achieve optimum performance. This front mount ERF will generate a slower focal ratio through aperture reduction while preventing heat build-up in the optical tube assembly.\u003c\/li\u003e\n\u003cli\u003eMaktsutov owners who operate at a native ~F\/15 focal ratio do not need to reduce the aperture of the telescope, but must use front mount energy rejection to prevent overheating of the optical tube assembly.\u003c\/li\u003e\n\u003cli\u003eExact filter bandpass will vary based on final telescope application, so QUARK assemblies are qualified to show either prominences or surface (chromosphere).
