The Sun in Hydrogen-Alpha: Full Solar Disk
Sunday, June 28th, 2026 at 4:32:39 PM · 2026/Astrophotography
A stunning full-disk hydrogen-alpha (Hα, 656.3 nm) image of the Sun captured on 28 June 2026 from Walnut Creek, California, rendered in false-color warm tones. The chromosphere is rendered in exquisite detail, showcasing multiple active regions with dark sunspots near the solar center, bright plage regions indicating strong magnetic activity, and long dark filaments snaking across the disk. Around the solar limb, delicate prominences erupt into the surrounding space, glowing in orange against the black background. The image was acquired with a Lunt LS60 60mm Hα solar telescope paired with a ZWO ASI585MM monochrome camera, with the best 1500 of 6838 frames selected and drizzle-stacked at 2× super-resolution for exceptional clarity. Post-processing via a custom Python lucky-imaging and drizzle pipeline — including multiscale sharpening and an asinh prominence boost — elevates this to a technically and artistically exceptional piece of solar astrophotography.
