Details
The DayStar Combo Quark Prominence Filter transforms your compatible telescope into a powerful solar observing instrument, revealing the Sun's dynamic prominences in stunning hydrogen-alpha light. Designed for SCTs, Maksutov telescopes, and refractors with focal ratios from f/15 to f/30, this compact, all-in-one device simplifies solar viewing by integrating the essential filtering components into a single, easy-to-use eyepiece-sized assembly.
Ideal for solar enthusiasts seeking detailed views of solar prominences, this filter offers an accessible way to explore the Sun's vibrant outer atmosphere safely and effectively when paired with the appropriate energy rejection filter.
Seamless Integration with Your Telescope
The Combo Quark fits directly into your telescope's diagonal or focuser via a 1.25" nosepiece, eliminating the need for additional adapters. Its included 2° off-axis adapter ensures compatibility with SCT and Maksutov telescopes equipped with off-axis energy rejection filters, creating a simplified setup that minimizes weight and complexity.
Optimized Optical Performance
Engineered with precision baffles and anti-reflective coatings tailored for the 656nm wavelength, this filter enhances contrast and clarity, allowing you to witness the Sun's prominences with exceptional detail. The integrated blocking filter and clear aperture ensure optimal light transmission and safety.
Fine Tuning for Precise Observation
A convenient tuning knob offers wing shifting adjustments within a narrow range, enabling you to lock in the perfect hydrogen-alpha wavelength for your observing session. Detents at every 0.1Å provide tactile feedback for precise control, enhancing your solar viewing experience.
Compact and Energy Efficient Design
This lightweight unit operates on USB power, with an included international AC adapter and an optional portable battery pack for extended use. Its reduced power consumption means you can enjoy solar observations throughout the day without hassle.
Safe and Reliable Operation
To protect your telescope and ensure safe solar viewing, the Combo Quark requires the use of an off-axis energy rejection filter with SCT and Maksutov telescopes. Its thoughtful design includes a brass compression ring to safeguard your eyepiece, and it comes with a five-year warranty for peace of mind.
Convenient Storage and Expandability
The filter ships in a durable twist-case that keeps it protected and dust-free when not in use. Optional accessories, including 2" eyepiece holders and camera adapters, expand its versatility for imaging and video applications.
