Sky-Watcher - Heliostar 76Ha Solar Telescope
The Heliostar 76mm H-alpha Solar Telescope is a new addition to the Sky-Watcher collection, featuring a dedicated Hydrogen-alpha (Hα) solar telescope. Viewing the Sun through Hydrogen-alpha reveals a much deeper insight into its surface activity, far exceeding the capabilities of a white light solar filter.
Sky-Watcher - Heliostar 76Ha Solar Telescope
Heliostar 76Ha
- Heliostar 76mm H-alpha Solar Telescope is a new addition to the Sky-Watcher lineup, offering a dedicated Hydrogen-alpha (Hα) solar telescope.
- Provides deeper insights into the Sun’s surface dynamics, surpassing white light solar filters.
- Allows observation of solar prominences, sunspots, plage areas, surface granulation, plasma filaments, and more, capturing stunning solar views and images.
- Hydrogen Alpha (Hα) solar telescopes observe the Sun at a specific wavelength of 656.3 nm, essential for detailed studies of prominences, filaments, sunspots, and solar flares.
- Unlike white-light telescopes, Hα telescopes focus on solar activity in the chromosphere, just above the photosphere.
- Meets ISO12312-2 safety standards after rigorous testing.
- Features Trifid Tuning and Solid Etalon systems, delivering double-stack performance at the cost of a single etalon filter.
- Tuned to <0.55Å for detailed surface views, with high-resolution observations made easy by its 76mm aperture.
- Comes equipped with a Vixen-style dovetail, Heliostar solar finder, Dual Speed Crayford Focuser, 11.5mm blocking filter, clip-on sunshade, 20mm 70° eyepiece, camera phone adapter, and carry case.
H-Alpha Solar Observation
The Heliostar 76mm H-alpha Solar Telescope introduces a fresh addition to the Sky-Watcher family, offering a specialized Hydrogen-alpha (Hα) solar telescope. Observing the Sun through Hydrogen-alpha provides a deeper understanding of its surface dynamics, far surpassing what a white light solar filter can show. With this telescope, you can observe solar prominences at the Sun's edge (often mistakenly called 'flares'), active sunspot regions, bright plage areas, surface granulation, delicate plasma filaments, and more, allowing you to capture stunning views and images of our star.
Hydrogen Alpha (Hα) solar telescopes are specialized tools designed to observe the Sun at a specific wavelength of 656.3 nm, which corresponds to the red line in hydrogen's Balmer series emission spectrum. This wavelength is essential for studying solar events such as prominences, filaments, sunspots, and solar flares in high detail. Unlike standard white-light telescopes, which capture the Sun's full spectrum, Hα solar telescopes focus on specific solar activity occurring in the chromosphere, a layer of the Sun's atmosphere just above the photosphere.
ISO12312-2 safety standards have been met with various testing.
Trifid Tuning and Sky Watcher's Solis Etalon System - Double Stack <0.55Å Bandpass - No Double Stack Filter Needed
With their own Trifid Tuning and Solid Etalon systems, the Heliostar 76mm Hα Solar Telescope delivers exceptional double-stack performance at the cost of just a single etalon filter. There's no need for expensive double-stack setups, as the 76Hα is inherently tuned to <0.55Å, offering detailed surface views. With its 76mm aperture, it allows for high-resolution observations and imaging with ease.
