DayStar Instruments Quark Prominence Filter
Available on backorder
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. Through design efficiency and optimization, now users can enjoy the known high quality optics of DayStar* at an affordable price.
This is the prominence (bandpass 0.8-0.6Å) optimized version of the Daystar Quark. It shows prominences that appear bright and detailed against a jet black background sky again with no sweet spot issues.
For use on refractors of F/4 to F/8**, the user needn’t worry about configurations. Just insert in your diagonal, add an eyepiece and view.
The patent pending QUARK* contains a custom Daystar Instruments 4.2X telecentric barlow lens fully optimized in coatings and optical design specifically for the Hydrogen Alpha wavelength. This highly specialized telecentric lens offers superior field flatness.
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. DayStar 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.
