The Heliostar 150 is a telescope dedicated exclusively to observing the Sun in H-alpha light, the line that reveals the chromosphere: prominences on the limb, filaments, flares and the active structures around sunspots. With 150 mm of aperture it is the largest model in the Heliostar family and delivers a brighter, more detailed image than its smaller siblings.
Technology
- Solis etalon: achieves a very narrow bandpass, below 0.5 Å, without needing a second etalon.
- Trifid Tuner: a mechanical adjustment that lets you fine-tune the etalon precisely and optimize image contrast.
- Solar Zenit diagonal: includes the integrated 24 mm blocking filter.
