DayStar Spotting Scope Quark - Prominence

The DayStar Instruments Spotting Scope Quark - Hydrogen-Alpha Filter with a choice of Chromosphere or Prominence is now in for Spotting Scope owners. This 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 Instruments at an affordable price.


For use on Spotting Scopes. The user needn't worry about configurations. Just thread the Spotting Scope Quark into the barrel, add an eyepiece and view.
- Exact filter bandpass will vary based on final scope application, so QUARK assemblies are qualified to show either prominences or surface (chromosphere). No specific Full-Width-at-Half-Maximum (FWHM) bandpass is designated. Either model is available for the same price.
- Now observers can select a filter to buy based on their desired observing goals instead of their budget. Choose between prominences and surface (Chromosphere) detail. Both selections 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. 

Some Specifications and Features: 

  • Baffles have been added to increase contrast and AR coatings are optimized for the 656 nm wavelength. We even reduced power consumption, so the Quark can now operate all day off an optional small, palm-sized battery pack. Not for use with full aperture SCTs, or damage to your secondary mirror may result. SCTs must use an off-axis ERF, sold separately. 
  • There is a brass compression ring to protect your eyepiece. Uses USB power, 5V 1.5 amp Includes 90 to 240VAC wall adapter with international plug adapters. Tuning knob allows wing shifting +/- 0.5A with detents at every 0.1A LED indicator for power, warming, ready, fault.
