Details
The Sky-Watcher Heliostar 76mm H-Alpha Solar Telescope is a specialized instrument designed for dedicated solar observation. Perfect for enthusiasts eager to explore the Sun's dynamic surface, this telescope reveals intricate solar phenomena invisible to regular white-light filters. It offers stunning views of prominences, sunspots, filaments, and other chromospheric details, making it ideal for both visual observers and solar imagers.
Equipped with advanced technology, this telescope delivers high-contrast solar images without the complexity or expense of traditional double etalon systems. Whether you're preparing for the upcoming solar maximum or involved in solar research and education, the Heliostar 76mm provides a reliable and safe platform to study our closest star.
Exceptional Solar Detail
Utilizing a finely tuned etalon filter, this telescope isolates the Hydrogen-alpha wavelength, unveiling the Sun's chromosphere in rich detail. Users can witness delicate plasma filaments, bright active regions, and the ever-changing solar surface with clarity rarely accessible outside professional observatories.
Innovative Etalon Technology
The integrated Solis etalon technology achieves a narrow bandpass under 0.55 angstroms, delivering performance comparable to costly double etalon setups but maintaining superior brightness. This innovation ensures users enjoy vivid contrast and intricate solar structures without sacrificing image brightness.
Precise Tuning Mechanism
Featuring the Trifid tuning system, the telescope allows accurate adjustment of the etalon filter by applying controlled pressure. This secure and stable tuning method enables observers to lock onto the precise Hydrogen-alpha emission line, accommodating shifts due to solar activity or atmospheric conditions.
Comprehensive Safety Features
Safety is paramount when observing the Sun. The Heliostar includes an 11.5mm blocking filter integrated into the eyepiece diagonal, tested to meet stringent international standards. This ensures safe solar viewing straight from the box, provided users follow recommended guidelines.
Ready-to-Use Accessories
Outfitted with mounting rings, a V-style dovetail, a solar finder, and a dual-speed Crayford focuser, the telescope is designed for ease of use. Included accessories like a sunshade, 20mm eyepiece, camera phone adapter, and a durable carrying case make this a complete solar observation kit ready for field use.
SolarQuest Tracking Mount
The optional SolarQuest mount offers automated solar tracking with one-button alignment via built-in GPS and HelioFind technology. Its lightweight design and adjustable tripod make it an excellent companion for extended solar sessions, educational settings, and eclipse chasing.
