The Sun has never been more exciting to observe. Now, there’s a powerful new way to experience it. Meet the HELIOSTAR 100Hα, a premium 100mm hydrogen-alpha solar telescope engineered for serious observers and imaging enthusiasts who want to explore the dynamic surface of our nearest star in stunning detail.
Join us April 4th, 2026 at the store for a live demo of this new telescope. We'll have Jeff Simon from SkyWatcher here, and you'll get a early chance to see the Heliostar 100 in action, and ask your questions.
WHEN: April 4th 2026 12-3pm PST
WHERE: 5348 Topanga Canyon Woodland Hills, CA 91364
See the Sun Like Never Before
Unlike traditional white light solar filters, hydrogen-alpha (Hα) observing reveals the Sun’s active, ever-changing chromosphere. With the HELIOSTAR 100Hα, you can witness:
- Towering solar prominences dancing along the limb
- Complex filaments stretching across the solar disk
- Active sunspot regions and bright plage
- Fine surface detail and evolving solar activity in real time
With a ≤0.5 Angstrom bandpass, this telescope isolates the specific wavelength of hydrogen-alpha light (656.28nm), delivering high-contrast, richly detailed views that bring solar activity to life.
Precision Engineering Meets Simplicity
At the heart of the HELIOSTAR 100Hα is advanced optical performance powered by Sky-Watcher’s Solis etalon technology. This innovation achieves a tight 0.5Å bandpass without the need for a dual etalon system, reducing both cost and complexity while maintaining exceptional image quality.
Whether you're observing visually or capturing solar images, you’ll get impressive performance right out of the box with no upgrades required.
The HELIOSTAR 100Hα isn’t just a telescope, it’s a complete solar observing solution. Included accessories like a 22mm wide-angle eyepiece, solar zenith prism, and solar guider ensure you can start observing immediately, whether you’re a seasoned astronomer or stepping into solar viewing for the first time.
Built for Safety and Confidence
Solar observing demands precision—and safety. The HELIOSTAR 100Hα is designed with multiple layers of protection, including:
- Infrared (IR) thermal reflection to minimize heat
- UV and heat-blocking filters
- Advanced stray light suppression for better contrast
It meets ISO 12312-2:2015 standards for safe solar viewing, giving you peace of mind while exploring the Sun.
A New Era of Solar Exploration
With increasing solar activity and more eyes turning skyward, there’s never been a better time to explore the Sun. The HELIOSTAR 100Hα delivers the performance, safety, and ease-of-use needed to make every observing session unforgettable.
If you’ve been waiting for the right moment to step into hydrogen-alpha solar astronomy, or upgrade your current setup, this is it.
