The Skywatcher Solar Telescope ST 76\/630 Heliostar-76 H-alpha<\/strong> is an impressive and safe solar telescope for observing active solar phenomena such as prominences, solar flares and granulation. Thanks to its extremely narrow H-alpha bandwidth of less than 0.5 \u00c5ngstr\u00f6m, this telescope reveals details that remain invisible with ordinary solar filters.<\/p>\n\n\n\n

The Heliostar uses a high-performance Etalon filter<\/strong> which passes only light with a wavelength of 656.28 nanometers - the characteristic light emitted by hydrogen. In this particular H-alpha line, the chromosphere of the sun<\/strong> visible, the area in which spectacular phenomena occur: fiery prominences, filaments, spikules and solar flares that can be followed in real time.<\/p>\n\n\n\n

\n
\"Skywatcher<\/figure>\n<\/figure>\n\n\n\n

Unlike many other systems with a dual Etalon stack, the Heliostar achieves this performance with only one filter element. This provides lower weight, easier operation and a more favorable price, without compromising image quality.<\/p>\n\n\n\n

Safety is paramount with this telescope. All optical elements are equipped with filters and coatings that block harmful UV and infrared radiation. The integrated <\/font><\/font>sunfinder <\/font><\/font><\/strong><\/font>makes<\/font><\/font><\/strong> it easy to safely center the sun without looking directly at it.<\/font><\/font><\/p>\n\n\n\n

\n
\"\"<\/figure>\n<\/figure>\n\n\n\n

The blocking filter<\/strong> with a diameter of 11.5 mm is located in the included eyepiece adapter and provides comfortable and safe observation. The 1.25\u2033 connection can also be unscrewed to allow a T2 thread<\/strong> expose, allowing compatibility with planetary cameras - ideal for solar photography in the H-alpha band. The optics provide a sharp, high-contrast image at magnifications up to about 150x.<\/p>\n\n\n\n

The high-quality <\/font><\/font>Crayford focuser<\/font><\/font><\/strong> with a 2\u2033 mount offers smooth and precise adjustment, allowing both visual observers and photographers to achieve maximum sharpness. Thanks to the Vixen-style dovetail, the telescope fits almost any standard mount. The included carrying case also provides secure storage and transport.<\/font><\/font><\/p>\n\n\n\n

Application<\/strong><\/h3>\n\n\n\n

The Skywatcher Heliostar-76 is designed for anyone who wants to observe the sun in its full dynamics.
What you can see with it:<\/p>\n\n\n\n

    \n
  • Dramatic prominences at the solar rim<\/li>\n\n\n\n
  • Dark filaments in the chromosphere<\/li>\n\n\n\n
  • Bright solar flares (flares) in real time<\/li>\n\n\n\n
  • Structure in the solar surface, such as spikules and granulation<\/li>\n\n\n\n
  • High-resolution sunspots<\/li>\n<\/ul>\n\n\n\n

    Use the telescope only according to the safety instructions<\/strong>. Never observe the sun without the integrated block filter and optical system.<\/p>\n\n\n\n
