Details

Magnesium, a bright green color is easily visible in the center of the human eye's highest sensitivity. Studies of the Mg line relate to boundary layers between granulation and spicule. In addition to heavy surface mottling and high contrast granulation, the Mg line also shows plages in equal or higher detail as the Calcium line. Magnesium wavelength studies will reveal Zeeman splitting in absorption of magnetized areas of active regions.

 

 

For 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. 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. DayStar even reduced power consumption, so the Quark can now operate all day off a small, palm-sized optional battery pack (not included in the box).
