Solar prominences, active sunspots, plage patches, surface granulation, wispy plasma filaments—these fascinating features and more await your gaze through the Heliostar 76mm H-Alpha Solar Telescope with SolarQuest Mount Kit from Sky-Watcher. The telescope and the mount-and-tripod kit are purpose-built for safe solar viewing: the mount finds and tracks the sun automatically, and the telescope singles out the hydrogen-alpha wavelength from the light spectrum for the richly detailed view it provides of our home star.
Sky-Watcher Heliostar 76mm f/8.3 H-Alpha Solar Telescope (OTA Only)
The Sky-Watcher Heliostar 76mm f/8.3 H-Alpha Solar Telescope is a dedicated optic for solar viewing only. This is no general-use refractor with a solar filter over the aperture—the Heliostar is built with a highly precise Solis etalon bandpass filter, refined by a Trifid tuner, to block all but a 0.55-angstrom sliver of hydrogen-alpha light. That light, in the 656.3nm wavelength, permits observation of solar phenomena in rich detail, including prominences, filaments, sunspots, and solar flares.
The Heliostar also features a blocking filter in the eyepiece diagonal and meets ISO 12312 safety standards. It comes with a 20mm 1.25" eyepiece with a 70° angle of view that provides 32x magnification and a smartphone adapter so you can capture and share the remarkable sights you see.
Optical Performance
- 76mm objective lens
- 630mm focal length
- Focal ratio: f/8.3
- Achromatic doublet lens design, H-alpha fully multicoated design
- Integrated Solis etalon filter technology with Trifid tuning system
- Passes only hydrogen-alpha 656.3nm bandwidth, which enables detailed observation of prominences on the limb of the sun, active sunspot regions, bright plage patches, surface granulation, snake-like plasma filaments, and more
- 11.5mm, 1.25" diagonal format blocking filter
- Meets ISO 12312 safety standards
Focuser
- 2" diameter focuser
- Dual-speed Crayford-style
- Crayford focusers use a toothless friction system that allows for super-fine precision focusing without backlash
Included Accessories
- 20mm 70° 1.25" eyepiece, 32x magnification with this telesxcope
- Integrated Heliostar solar finder
- Tube rings and carry handle
- Vixen-style dovetail bar
- Clip-on sunshade
- Hard-shell carry case
