DayStar Questar Quark - Chromosphere or Prominence

The DayStar Instruments Questar Quark - Hydrogen-Alpha Filter with a choice of Chromosphere or Prominence was new in the Fall of 2015 to Questar 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 3.5 Inch Classic Questar Maktsutov telescopes. The user needn't worry about configurations. Just thread the Questar Quark in either port, add an eyepiece and view.
Note: Questar users need to purchase an Energy Rejection Filter 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 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. 
  • The front, male combo threaded eyepiece snout with 2 unique mating threads is specifically matched to the QUESTAR axial and rear ports. The QUESTAR Quark can come to focus in the axial port with or without the Barlow magnification lens engaged. 
  • 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.
