Skywatcher Heliostar 76 H-Alpha Solar Telescope with SESTO SENSO

The SkyWatcher Heliostar 76mm H-Alpha Solar Telescope opens a new window into the dynamic surface of our star. Designed specifically for observing the Sun in the Hydrogen-alpha (Hα) wavelength at 656.28 nm, it reveals incredible chromospheric details invisible through standard white-light filters — including solar prominences, filaments, flares, and fine granulation.

With its 76mm aperture and 630mm focal length (f/8.3), the Heliostar provides crisp, high-resolution images. Its Solis Etalon technology with integrated tuner delivers a native <0.55Å bandpass, achieving double-stack level performance without the need for additional etalons. This makes it an exceptional choice for both visual observation and advanced imaging, offering excellent surface contrast and limb detail.
