Sky-Watcher Heliostar 100: The Solar Observatory<\/h2>\n

The Sky-Watcher Heliostar 100 is merk\u2019s large H-alpha solar telescope: a 100 mm aperture at f\/7.6 for maximum resolution of prominences, filaments, and active regions. The 2.8-inch dual-speed focuser, the blocking filter, and the safe solar finder make it a complete solar observatory, supplied with a 22 mm 70-degree wide-angle eyepiece.<\/p>\n

What do you see in H-alpha?<\/h2>\n

A completely different sun than through a regular solar filter. Prominences hanging like flames at the edge, dark filaments like streamers across the surface, bright flares around active regions, and the churning granulation of the surface itself. With a white-light filter, you see sunspots; in H-alpha, you see the sun alive.<\/p>\n<\/div>\n<\/div>\n

Safety first<\/h2>\n

This telescope is designed as a complete H-alpha system for the sun: the etalon and blocking filter form a closed, safe unit. Use it exclusively as supplied, check for damage to all filters before each session, and never let children look through a solar telescope unsupervised. If you have any doubts about damage, do not use it and contact us.<\/p>\n<\/div>\n<\/div>\n
