With the SkyWatcher Heliostar 76/630 H-alpha solar telescope, you can observe spectacular activity on our central star, such as prominences, which cannot be seen with conventional telescopes.
The SkyWatcher Heliostar 76/630 H-alpha solar telescope is the renowned manufacturer’s first instrument specifically developed for amateur astronomers to observe solar phenomena visible in the H-alpha wavelength range. It allows observation of prominences along the Sun’s limb, as well as surface and chromospheric details and active phenomena such as solar flares, which are not visible in white light.
At the heart of the instrument is a filter optimized for the 656.28 nm H-alpha wavelength, with a bandwidth below 0.5 Å. The tuning ring allows fine adjustment of the filter to enhance either solar surface details or prominences. The blocking filter has a diameter of 11.5 mm, allowing the entire solar disc to fit within the field of view, making the instrument well suited for imaging.
The 76 mm solar telescope features a 630 mm focal length and an F/8.3 focal ratio. Focusing is provided by a 2" dual-speed Crayford focuser. Aligning the Sun is quick and easy with the solar finder integrated into the handle connecting the tube rings.
The finely crafted optical tube of the SkyWatcher Heliostar 76/630 weighs just 3.8 kg. This makes it easy to transport and convenient to use even on mounts with lower payload capacity.
