Daystar Filters SODIUM Quark filter

Daystar Filters SODIUM Quark Filter

• Innovative Sodium D-Line Technology: Introducing the Sodium D-line version of the Quark, designed specifically for use in refractors F/4-F/9.
• Enhanced Sunspot Detail: Offers high-resolution sunspot detail, plague, granulation, and potentially super-granulation, depending on the observer's resolution and seeing conditions.
• Flare Footprint Visualization: Capable of showing flare footprints, also known as flare kernels, highlighting the initial stages of solar flares.
• Brighter than Calcium and Hydrogen Alpha: The Sodium D line is brighter, enabling easy observation and very short exposures for observers.
• Sodium D2 Line Focus: Concentrates on the D2 line at 5890, ensuring precise solar observations.
• Narrow Bandpass: All Sodium D line Quarks feature a bandpass of 0.5 or narrower, for focused and detailed imaging.
• All-In-One Design: Combines a telecentric barlow, adapters, snouts, and the Daystar MgI b2 line filter into a single, efficient assembly.
• Easy Setup: Simply insert in the diagonal, add an eyepiece, and view; no complex configurations needed.
• Custom Telecentric Barlow Lens: Includes a custom Daystar Instruments 4.2X telecentric barlow lens, optimized for excellent field flatness.
• Adaptable Filter Bandpass: The exact filter bandpass varies based on the telescope application, with etalons ranging approximately from 0.3-0.5 angstroms.
• User-Focused Design: Eliminates the need for additional adapters, integrating all components into a lightweight, eyepiece-sized device.
• Energy Efficiency: Features reduced power consumption, allowing operation all day off a small, optional palm-sized battery pack.
• Flexible Eyepiece Compatibility: Offers 1.25" or 2.0" combo eyepiece snouts with safety indent slot for easy diagonal insertion.
• Accessory Options: Standard 1.25" eyepiece drawtube output, compatible with optional 2" and SCT accessories.
• Protective and Adjustable Features: Brass compression ring for eyepiece protection, tuning knob for wing shifting, LED indicators for operational status.
• Extended Warranty: Comes with a 5-year warranty for long-term reliability.
• Optimal Performance Range: Best suited for F/4 - F/8 refractors, allowing full disk viewing on refractors up to ~450mm focal length.
• Convenient Storage: Ships in a Twist-Case for safe, dust-free storage.
• Application Note: Not suitable for off-axis applications.
