The Heliostar 100Hα is a precision tool for solar astronomy, offering a full suite of accessories including a 22mm 70° wide-angle eyepiece, solar zenith prism, and solar guider.\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan\u003eHydrogen-alpha solar observing allows you to unlock the incredible dynamics of surface of the Sun far beyond what a white light solar filter can deliver. From solar prominences on the limb of the Sun (often mistakenly called 'flares'), to active sunspot regions, bright plage patches, surface granulation, wispy, snake-like plasma filaments, and more, the star of the solar system is yours to capture in breathtaking views and images. When viewing the Sun in the narrow H-alpha bandwidth, the observer is rewarded with thrilling, awe-inspiring real-time views of our nearest star in it's full fiery majesty, seething with activity.\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan\u003eThe HELIOSTAR-100Ha uses multiple technologies to protect the human eye during solar observation, including an infrared thermal ray reflection film, a special filter to block heat, and a filter to block UV light from entering, blocking stray light that affects observation. It uses a combination of front and rear filters to allow only monochromatic light with a wavelength of 656.28 nanometres emitted by hydrogen atoms to pass through, whilst blocking other light of different wavelengths. This allows the observation of quite active prominences in the H-Alpha band.\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan\u003eSky-Watcher's Solis etalon technology allows the Heliostar-100Ha to achieve a 0.5A bandpass without the costly expense and complexity of a second etalon to achieve the same performance. This allows the observer to obtain detailed images of the solar disk right out of the box without any further expense.\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan\u003eThe HELIOSTAR-100Ha conforms to and meets the transmission requirements of ISO 12312-2:2015 (Filters for the direct observation of the Sun).
