This remarkable hydrogen-alpha solar image was captured on July 4, 2026 using a Lunt LS60THa dedicated solar telescope paired with a ZWO ASI585MM monochrome camera on an EQ-G equatorial mount. The image reveals the Sun's chromosphere in extraordinary detail, showcasing dark filaments threading across the solar disk, bright plage regions near active areas in the upper portion, and several solar prominences arcing along the limb — most notably visible at the upper edge. The warm golden-amber false coloring is characteristic of hydrogen-alpha solar photography, which isolates the 656.28nm emission line of ionized hydrogen. The full-disk presentation was produced using a lucky-imaging true-HDR fusion pipeline (rim v5) with 2x drizzle processing, which enhances resolution and dynamic range to simultaneously capture fine chromospheric texture and delicate limb prominences.
