Details
The Sky-Watcher Heliostar 76mm H-alpha Solar Telescope is designed for enthusiasts eager to explore the Sun's dynamic surface in extraordinary detail. Ideal for both visual observation and imaging, this specialized instrument reveals solar phenomena far beyond the reach of conventional white light filters, capturing features such as prominences, sunspots, and plasma filaments with striking clarity.
Engineered to meet the needs of serious solar observers, the Heliostar combines advanced optical technology with user-friendly features, making it an excellent choice for anyone seeking safe and detailed views of our nearest star.
Exceptional Hydrogen-alpha Imaging
This telescope isolates the specific 656.3 nm wavelength of hydrogen-alpha light, unveiling the Sun's chromosphere and its intricate activity. Observers can witness solar prominences, spicules, and active regions with enhanced contrast, providing a vivid and engaging solar experience.
Advanced Etalon Filter Technology
Equipped with the innovative Solis Etalon system, the Heliostar achieves a narrow bandpass below 0.55Å, delivering double-stack level performance without the complexity or brightness loss typically associated with dual etalon setups. This streamlined approach allows for detailed solar observations with simpler operation.
Precision Tuning with Trifid Tuner
The integrated Trifid Tuner applies controlled pressure to the etalon plates, enabling fine adjustments to the transmitted wavelength. This feature ensures optimal alignment with solar emission lines, accommodating subtle shifts caused by atmospheric conditions or solar dynamics.
Robust Optical Design
Featuring a 76mm aperture and 630mm focal length with an achromatic doublet lens, the telescope provides sharp, high-resolution views. Its fully multicoated hydrogen-alpha lens enhances light transmission and contrast, while a dual-speed Crayford focuser allows for smooth and precise focusing.
Comprehensive Accessory Set
Ready for immediate use, the Heliostar includes mounting rings, a V-style dovetail, a dedicated solar finder, a 20mm 70° eyepiece, an 11.5mm blocking filter in a specialized diagonal for safety, a clip-on sunshade, and a camera phone adapter. All components are housed in a durable carrying case for convenient transport and setup.
Safety and Reliability
Each telescope is individually tested to meet rigorous ISO safety standards for solar observation. The included blocking filter and dedicated diagonal ensure safe viewing, emphasizing the importance of proper handling when observing the Sun.
