Solar Chromosphere in Hydrogen-Alpha Light

This stunning hydrogen-alpha solar image captures the Sun's chromosphere at 656.3nm wavelength, revealing fine surface detail invisible in white light. The granular texture of the solar surface is clearly visible, along with dark sinuous filaments — suspended magnetic plasma structures — arching across the disk, particularly prominent in the western hemisphere. The brilliant orange-red limb glows with small prominences and spicules erupting into the corona. The image was produced using a Lunt LS60THa 60mm f/8.3 hydrogen-alpha telescope at 500mm focal length, a ZWO ASI585MM monochrome camera, and a Sky-Watcher EQ6 tracking mount. A multi-exposure HDR ladder combined with lucky-imaging stacking and 2x drizzle processing produced exceptional sharpness and dynamic range across the full solar disk.
