Daystar Instruments QUARK is the first Hydrogen Alpha
COMBO CHROMOSPHERE MODEL for SCTs, Maks, or F/15 and longer
This new, All-In-One design marries high quality components of 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 SCTs, Maks, or refractors of F/15 to F/30, the user needn't
worry about configurations. Just insert in your diagonal, add an eyepiece and
view. SCT and Mak users need only to purchase an off axis ERF specific to their
telescope for safe operation. 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.
Not for use with full aperture SCTs/Maks, or damage to your secondary
mirror will result. SCTs/Maks must use an off axis ERF, sold separately.

Filters' Fabry Perot etalon technology.
