The HELIOSTAR 100Hα Solar Telescope is a premium 100mm hydrogen-alpha (H-alpha) solar telescope engineered for serious solar observers and astrophotography enthusiasts. Delivering an exceptional ≤0.5 Angstrom bandpass, this high-performance solar scope reveals extraordinary detail across the Sun’s surface, making it ideal for both visual observation and solar imaging.

Designed as a complete solar observing system, the HELIOSTAR 100Hα includes a 22mm 70° wide-angle eyepiece, solar zenith prism, and solar guider, everything you need to begin capturing stunning solar views right out of the box.

Hydrogen-alpha solar observing unlocks dynamic features of the Sun that are completely invisible with standard white light solar filters. With the HELIOSTAR 100Hα, you can observe:

• Dramatic solar prominences extending from the Sun’s limb
• Active sunspot regions and evolving solar activity
• Bright plage areas surrounding sunspots
• Intricate surface granulation and chromospheric texture
• Flowing solar filaments and plasma structures

This narrowband H-alpha solar telescope isolates light at 656.28 nanometers, allowing you to experience the Sun as a constantly shifting, highly active star in stunning real-time detail.

The HELIOSTAR-100Hα incorporates multiple layers of solar protection and precision filtering to ensure safe and high-contrast viewing:

• Infrared (IR) thermal reflection film to reduce heat buildup
• UV and heat-blocking filters for eye safety
• Stray light suppression for improved contrast
• Front and rear filtering system for precise wavelength isolation

Only monochromatic hydrogen-alpha light passes through the system, ensuring optimal visibility of solar activity while maintaining strict safety standards.

Powered by Sky-Watcher’s advanced Solis etalon technology, the HELIOSTAR 100Hα achieves a 0.5Å bandpass without requiring a dual etalon system. This innovation reduces cost and complexity while still delivering high-contrast, detailed views of the solar disk, perfect for observers who want premium performance without additional upgrades.

The HELIOSTAR-100Hα meets the ISO 12312-2:2015 international safety standard for direct solar observation. Always follow proper solar viewing guidelines and use the telescope as instructed to ensure safe operation.

The Sky-Watcher Wave 100i Strainwave Mount is a compact, high-precision mount designed for astrophotographers and visual observers alike. Weighing just 9.5 lbs, it delivers an impressive payload capacity of 22 lbs without a counterweight and up to 33 lbs with one, making it ideal for a wide range of setups.

Built on strain wave (harmonic) drive technology, the Wave 100i provides smooth, low-backlash tracking with excellent accuracy—perfect for long-exposure imaging. It features a 300:1 transmission ratio for precise control, a fast 2400x slew rate (10°/sec), and supports sidereal, lunar, and solar tracking.

With dual AZ/EQ capability, a wide 0°–90° latitude range, and a dual Vixen/Losmandy saddle, the Wave 100i offers versatility, portability, and performance in one streamlined package.
