QUARK MANUAL PDF
For use in refractors from F/4 to F/7 and up to 80mm aperture the user does not need to worry about settings.
Just insert it into your diagonal, add an eyepiece, and see.
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 4.2x telecentric lens offers superior field uniformity and allows you to achieve the device's ideal working focal length between F15 and F30.
The exact bandpass filter will vary depending on final telescope assemblies, so QUARK is qualified to display prominence or surface (chromosphere). A specific FWHM bandpass is not designated.
Now observers can choose to purchase a filter based on their observing goals rather than their budget.
Choose the prominences and detail of the surface (Chromosphere). Both are available for the same low price!
Fully optimized design eliminates the need for adapters.
Everything is combined in a lightweight device the size of an eyepiece.
The new compact design configuration eliminates unnecessary components, weight and associated costs. We've even reduced power consumption, so Quark can now run all day on an optional small, palm-sized battery.
Baffles have been added to increase contrast and the AR coatings are optimized for the 656nm wavelength.
*The QUARK array is a product of DayStar Instruments, utilizing DayStar Filters' Fabry Perot etalon technology.
