The Heliostar 100H\u03b1 is a precise tool for solar astronomy and comes with extensive accessories including a 22mm 70\u00b0 wide angle eyepiece, a solar zenith prism and a solar finder scope. <\/p>\n<p>Hydrogen-alpha solar observing allows you to observe the incredible dynamics on the sun&#8217;s surface that a white light solar filter cannot provide. Starting with the prominences at the edge of the sun, active sunspot regions, flares, solar granulation, thin, snake-like plasma filaments and much more, which you can experience during breathtaking observations or capture on photos. When observing the Sun in the narrow H-alpha wavelength, the observer is rewarded with exciting and impressive real-time observations of our nearest star with its fiery, majestic activity.  <\/p>\n<p>The HELIOSTAR-100H\u03b1 uses a variety of technologies to protect the human eye during observation, including a coating that reflects infrared radiation, a special filter that blocks heat, and a filter that blocks UV light and prevents the effects of stray light. It uses a combination of front and rear filters to allow only monochromatic light with a wavelength of 656.28 nanometers, which is emitted by the hydrogen atoms, to enter and block all other wavelengths. This allows the observation of active prominences in the H-alpha wavelength.  <\/p>\n<p>Sky-Watcher&#8217;s Solis Etalon technology allows the Heliostar-100H\u03b1 to achieve a very narrow bandwidth of just 0.5Angstrom without the need for an expensive second etalon with the same performance. This allows the observer to experience the sun in detailed images directly &#8220;out of the box&#8221; without additional, expensive accessories. <\/p>\n<p>The Sky-Watcher HELIOSTAR-100H\u03b1 complies with the transmission requirements of ISO 12312-2:2015 (filters for direct observation of the sun). Always use the telescope according to the instructions and always be particularly careful when observing the sun! <\/p>\n<p><em><strong>Safety information:<\/strong><\/em><\/p>\n<p><em><strong>Always be particularly careful when observing the sun. Improper use of the telescope can lead to serious and permanent damage to the eyes!<br \/>\nAttention: The 20mm blocking filter in the removable star diagonal mirror is part of the Heliostar safety equipment.
