Vai al moduloThe Sky-Watcher Heliostar 100mm H-alpha is a high-end solar telescope designed for experienced solar observers and astrophotographers. Featuring a bandwidth of <0.50Å, it reveals fine solar chromosphere details including prominences, flares, granulation, and filaments with sharp contrast and resolution.
Its 100 mm aperture and 800 mm focal length (f/8) combine with the Solis Etalon Technology and mechanical Trifid Tuner to provide professional-grade performance without the complexity or cost of a double etalon. The 2” dual-speed Crayford focuser ensures smooth, precise focusing for imaging or visual use.
A 20 mm internal blocking filter is integrated into the 1.25” Solar Zenit diagonal, offering safe and consistent performance. Each unit is individually tested under solar observation and fully compliant with ISO 12312-2 safety standards.
The Heliostar 100 pairs ideally with the Sky-Watcher SUNGT mount for a portable, fully automated solar tracking setup.
Important Note: This is a dedicated solar telescope designed exclusively for solar observation. Improper use may cause serious and permanent eye injury.
