The SkyWatcher Helostar 76/630 H-alpha solar telescope gives us insight into spectacular elements of our central star's workings, such as prominences, that would be impossible to observe with conventional telescopes.
The SkyWatcher Helostar 76/630 H-alpha solar telescope is the first instrument in the renowned manufacturer's lineup designed specifically for amateur astronomers to observe phenomena visible in the Sun's hydrogen-alpha wavelength range. You can catch glimpses of protuberances (solar flares) on the limb of our central star, as well as surface formations (flares) that are undetectable in visible light.
The heart of the telescope is a filter optimised for 656.28 nm wavelength (h-alpha) with a bandwidth of 0.5Ä. A ring is used to fine-tune the bandwidth of the filter to "focus" on the surface details of the Sun or on the protuberances. The block filter is 11.5 mm, which allows the entire solar disk to be covered, making it ideal for photography.
Diameter 76 mm, the solar telescope has a focal length of 630 mm and a brightness of F/8.3. Focusing is made possible by a 2", two-speed Crayford curtain. Finding the sun is quick and easy with the solar finder built into the grip that holds the tube rings together.
The sophisticated design of the tube, weighing 3.8 kg, makes it easy to carry, and smaller travel mechanics are sufficient to move it.
