Details
The DayStar Quark Solar H-alpha Filter is a precision optical accessory designed for solar observation and imaging. It enables astronomers to view the Sun in the hydrogen-alpha spectral line, revealing fine solar details such as prominences, filaments, and surface granulation that are invisible in white light.
Ideal for advanced amateur astronomers and solar imaging enthusiasts, this filter provides a dedicated solution for safe and detailed solar study, transforming standard telescopes into specialized solar instruments.
High-Precision Etalon
Feature: Internal narrowband etalon optimized for H-alpha wavelength.
Advantage: Isolates the hydrogen-alpha spectral line with a narrow bandpass.
Benefit: Delivers sharp and high-contrast views of solar chromospheric features.
Compact and Integrated Design
Feature: All-in-one filter unit with integrated blocking filter.
Advantage: Simplifies setup by eliminating the need for multiple filter components.
Benefit: Enhances user convenience and reduces optical alignment complexity.
Tuning Mechanism
Feature: Adjustable tuning control for precise wavelength alignment.
Advantage: Allows fine spectral adjustment to compensate for Doppler shifts and temperature changes.
Benefit: Ensures optimal filter performance and image clarity under varying observing conditions.
Compatibility
Feature: Designed to fit standard 1.25" eyepiece barrels.
Advantage: Compatible with a wide range of refractors and Maksutov-Cassegrain telescopes.
Benefit: Offers flexibility for integration with existing telescope setups.
Optical Coatings
Feature: Multi-coated optics throughout the filter.
Advantage: Minimizes reflections and maximizes light transmission.
Benefit: Produces brighter and clearer solar images with reduced ghosting.
