Details
The DayStar Combo Quark Chromosphere Filter is an innovative solar filter designed for amateur astronomers who want to explore the Sun's dynamic chromosphere in stunning detail. Ideal for use with SCTs, Maksutovs, and refractors operating between f/15 and f/30, this compact, all-in-one device transforms your telescope into a specialized solar observatory with minimal setup.
By integrating high-quality optical components, adapters, and a hydrogen-alpha filter into a single lightweight unit, it simplifies solar viewing without sacrificing performance. Whether you seek to observe subtle surface features or broader solar prominences, this filter offers a versatile solution tailored to your solar observing goals.
Streamlined Design for Easy Use
The Combo Quark eliminates the need for multiple adapters by combining essential elements into one eyepiece-sized device. This reduces weight and complexity, allowing quick installation directly into your telescope diagonal. Its compact form factor encourages spontaneous solar sessions without cumbersome setup.
Optimized Optics for Enhanced Contrast
With specialized anti-reflection coatings tuned to the hydrogen-alpha wavelength (656 nm) and internal baffles, the filter enhances solar contrast and clarity. This careful optical optimization reveals fine chromospheric details and subtle surface structures with remarkable sharpness.
Flexible Compatibility with Popular Telescopes
Designed for SCTs, Maksutovs, and refractors within a specific focal ratio range, the filter supports a variety of telescope types. Users must incorporate an appropriate Energy Rejection Filter (ERF) for safe operation, especially on SCT and Maksutov scopes, ensuring protection against heat buildup and maintaining optimal image quality.
Precision Tuning and User Control
A convenient tuning knob allows precise adjustment of the filter's passband, enabling observers to fine-tune views of the solar chromosphere. Detents at small increments provide tactile feedback for accurate positioning, while LED indicators communicate power and readiness status during use.
Portability and Power Efficiency
Powered via USB with a low current draw, the Combo Quark can operate off a compact battery pack for extended periods, making it suitable for field observations. It ships in a protective twist-case to keep the filter safe and dust-free between sessions.
