The Sky-Watcher Heliostar 76Hα is a specialized prominence telescope designed with advanced safety features to protect the observer’s eyes. It incorporates multiple technologies, including an infrared thermal reflection film to effectively block heat and a dedicated ultraviolet (UV) filter to eliminate harmful rays. These features work in tandem to minimize stray light, ensuring a safe and enhanced viewing experience.

Description

The Sky-Watcher Heliostar 76Hα is a specialized solar telescope designed for enthusiasts eager to explore the Sun’s dynamic features, particularly solar prominences. With a 76mm aperture and a focal length of 630mm (f/8.3), it offers a balanced combination of portability and detailed solar observation.

Key Features:

• Hydrogen-Alpha Observation: The Heliostar 76Hα utilizes a combination of front and rear filters to isolate the hydrogen-alpha wavelength at 656.28 nanometers. This narrowband filtering, with a bandwidth of less than 0.5 angstroms, enables observers to view solar prominences and surface details with exceptional clarity.
• Advanced Optical Design: Incorporating multiple technologies to protect the observer’s eye, the telescope features a thermal infrared reflection film, a special heat-blocking filter, and an ultraviolet light-blocking filter. These components work together to eliminate stray light and ensure safe solar viewing.
• Precision Focusing: Equipped with a 2-inch Crayford focuser, the Heliostar 76Hα allows for smooth and precise focusing adjustments, enhancing the overall observing experience.

The Sky-Watcher Heliostar 76Hα is an excellent choice for both novice and experienced solar observers, offering a safe and detailed view of the Sun’s dynamic phenomena.
