Sky-Watcher Heliostar 100Hα Solar Telescope

with Wave 100i Mount Kit

SKU S11335

• Bring the Sun into stunning hydrogen-alpha detail with the Sky-Watcher Heliostar 100Hα Solar Telescope and Wave 100i Mount Kit, a complete solar observing and imaging setup built for high-resolution views, outreach, and portable solar astronomy.
• The 100mm Hα optical tube delivers impressive double-stack-style performance at a single-stack price, using integrated Solis Etalon Technology and a Trifid Tuner to achieve a narrow <0.5Å bandpass for rich chromosphere contrast.
• View dramatic solar prominences, spicules, plage, filaments, active regions, sunspots, flares, and surface texture with far more dynamic detail than a standard white-light solar filter can provide.
• The Heliostar 100Hα is the official solar telescope of the Charlie Bates Solar Astronomy Project, making it an excellent choice for educators, clubs, eclipse chasers, and public outreach programs.
• A fully multicoated H-alpha lens and achromatic doublet design provide clean solar performance, while the 2.8-inch dual-speed rack-and-pinion focuser gives observers and imagers precise control.
• The included 20mm blocking filter diagonal is part of the telescope’s dedicated solar safety system and is designed specifically for use with the Heliostar.
• The Wave 100i GoTo strainwave mount adds compact power and precision, supporting up to 22 pounds without a counterweight or up to 33 pounds with an optional counterweight kit.
• EQ and AZ operating modes make this kit flexible for solar tracking, visual observing, imaging, and outreach setups where fast alignment and simple control matter.
• Built-in Wi-Fi, Bluetooth, RA power-off braking, home position functions, and red-lit setup aids help streamline your observing routine in the field.
• The included heavy-duty tripod with 2-inch rolled steel legs provides a strong foundation for the Wave mount system, with matching black trim for a clean Sky-Watcher setup.
