The Sun in Hydrogen-Alpha, Full Solar Disk
Sunday, June 28th, 2026 at 4:32:39 PM · 2026/Astrophotography
A high-resolution hydrogen-alpha (Hα, 656.3 nm) image of the full solar disk captured from Walnut Creek, California on 28 June 2026, using a Lunt LS60 60 mm solar telescope and ZWO ASI585MM monochrome camera. The chromosphere is rendered in rich golden-amber false colour, revealing multiple active regions with dark sunspots, bright plage surrounding them, and sinuous dark filaments arcing across the solar surface. Solar prominences are visible erupting around the limb, particularly prominent at the top of the disk, appearing as delicate reddish-orange structures against the black background of space. The extraordinary surface texture — the fibril and supergranulation structure of the chromosphere — is resolved across the entire disk thanks to drizzle super-resolution stacking of the best 1,500 frames from nearly 7,000 captured. This is a technically exceptional piece of solar astrophotography processed with a custom lucky-imaging and drizzle pipeline, including multiscale sharpening and an asinh prominence boost.
