Experience the Sun Like Never Before

Discover the dynamic beauty of our nearest star with the Heliostar 100 Hα. Featuring a full 100mm aperture, native <0.5Å H-alpha performance, and advanced Solis Etalon Technology with the Trifid Tuner, it reveals breathtaking prominences, filaments, plages, and surface detail straight out of the box.

Bigger Aperture. Greater Detail.

Every extra millimeter counts when observing the Sun.

The Heliostar 100 delivers a substantial increase in resolution and light gathering over smaller solar telescopes, allowing you to see finer chromospheric structures and capture stunning high-resolution solar images.

Whether you're observing towering prominences or intricate filament networks, the Heliostar 100 is built for exceptional visual performance and astrophotography.

Native Double-Stack Performance

Why compromise?

The Heliostar 100 achieves a native bandpass below 0.5Å, producing outstanding surface contrast without the expense or complexity of adding a second etalon. Advanced Solis Etalon Technology and the precision Trifid Tuner work together to deliver high-contrast views across the solar disk.
