DayStar Quark Hydrogen Alpha Chromosphere Eyepiece
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.
For use on refractors of F/4 to F/9, the user needn't worry about configurations*. Just insert in your diagonal, the Quark, add an eyepiece and view.
The 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.
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.
*Please note, the Quark may be used as a standalone unit with refractors up to 80mm in diameter. Between 80 and 100mm, a UV/IR Cut filter is required. Above 100mm, a front-mounted Energy Rejection Filter is required.
