The SkyWatcher Heliostar 100/760 H-alpha solar telescope provides insight into the spectacular elements of our central star's operation, such as prominences, which would be impossible to observe with traditional telescopes.
The SkyWatcher Heliostar 100/760 H-alpha solar telescope is the larger sibling of the 76/630 Heliostar, the second device in the renowned manufacturer's lineup specifically designed for amateur astronomers to observe phenomena visible in the Sun's hydrogen-alpha wavelength range. We can observe prominences (solar flares) on the edge of our central star, as well as surface formations (flares) that are undetectable in the visible light spectrum.
The heart of the telescope is a filter optimized for a wavelength of 656.28 nm (H-alpha) with a <0.5Å bandwidth. A ring allows for fine-tuning of the filter's bandwidth, enabling "focus" on the Sun's surface details or prominences. Its blocking filter is 11.5 mm, allowing the entire solar disk to fit into the field of view, making it well-suited for photography.
The solar telescope has a diameter of 100 mm, a focal length of 760 mm, and a focal ratio of F/7.6. Focusing is facilitated by a 2" dual-speed Crayford focuser. Finding the Sun is a quick and easy task with the solar finder built into the handle that holds the tube rings together.
The elegantly crafted tube, weighing 6 kg, is easily portable, and stronger load-bearing travel mounts are sufficient for its movement.
Observation can begin with the included 22 mm eyepiece with a 70° field of view, providing 35x magnification. Naturally, additional eyepieces can be used to exploit the telescope's full magnification range. The product also includes an aluminum case for storing and transporting the telescope.
