By popular demand, we are introducing a Sodium D line version of the Quark, for use in refractors F/4-F/9. Sodium gives outstanding views of active regions, plage, and granulation, in a pleasing yellow/orange color.
This new, All-In-One design marries high quality components of a telecentric barlow, adapters, snouts and Daystar Sodium D line 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.
This day/night combo offers incredible performance and value. For solar viewing just insert the Quark in the 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. Exact filter bandpass will vary based on final telescope application. No specific FWHM bandpass is designated, however the etalon will be approximately 0.3-0.5 angstroms. Now observers can buy a filter based on their desired observing goals instead of their budget. 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.
*The QUARK assembly is a product of DayStar Instruments, using DayStar Filters' Fabry Perot etalon technology.
