            <description>Sky-Watcher Heliostar 76 Hα

Overview

The Sky-Watcher Heliostar 76 Hα is a dedicated solar telescope designed exclusively for observing the Sun in the hydrogen-alpha (Hα) band at a wavelength of 656.28 nm. Unlike white-light filters, which show only the photosphere, an Hα telescope reveals the chromosphere — the outer layer of the Sun&#039;s atmosphere. This makes visible details that remain invisible through a standard solar filter: prominences, filaments, flares, and spicules.</description>

            <description>Sky-Watcher Heliostar 76 Hα

Überblick

Der Sky-Watcher Heliostar 76 Hα ist ein dediziertes Sonnenteleskop, das ausschließlich zur Beobachtung der Sonne im Wasserstoff-alpha-Band (Hα) bei einer Wellenlänge von 656,28 nm ausgelegt ist. Im Gegensatz zu Weißlichtfiltern, die lediglich die Photosphäre zeigen, ermöglicht ein Hα-Teleskop den Blick in die Chromosphäre – die äußere Schicht der Sonnenatmosphäre. Dadurch werden Details sichtbar, die mit einem normalen Sonnenfilter unsichtbar bleiben: Prot…</description>
