For use on Questar telescopes, the user needn't worry about configurations. Just insert in the diagonal, add an eyepiece and view. The QUARK contains a custom Daystar Instruments etalon and optical design specifically for the Hydrogen Alpha wavelength.  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.

*The QUARK assembly is a product of DayStar Instruments, using DayStar Filters' Fabry Perot etalon technology.
