Through design efficiency and optimization, now users can enjoy the known high quality optics of DayStar at an affordable price.\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eFor 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 QUARK contains a custom Daystar Instruments 4.2X telecentric barlow lens fully optimized in coatings and optical design. This highly specialized telecentric lens offers superior field flatness.\u003c\/li\u003e\n\u003cli\u003eExact filter bandpass will vary based on final telescope application. No specific FWHM bandpass is designated, but it will be around 0.5Å or lower. The fully optimized design eliminates the need for any adapters. It's all combined in one lightweight eyepiece sized device.\u003c\/li\u003e\n\u003cli\u003eThe 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.\u003c\/li\u003e\n\u003cli\u003eCompatible with yellow glass ERFs offered by Daystar.  Red glass ERF filters will not pass Sodium. Daystar also recommends use with a UV\/IR cut filter for safety. Users need to purchase an Energy Rejection Filterspecific to their telescope for safe operation.\u003c\/li\u003e\n\u003cli\u003eBaffles have been added to increase contrast and AR coatings are optimized for the 589nm wavelength.
