Sky-Watcher Heliostar 76mm H-Alpha Solar Telescope

This dedicated Hydrogen-alpha telescope features a 76mm aperture and f/8.3 focal ratio for detailed solar observation. It isolates the H-alpha wavelength with a specialised filter, revealing prominences, filaments and surface granulation. The instrument arrives ready to use with a rugged carrying case for portable operation.

Who this suits and who should look elsewhere

Solar enthusiasts wanting a complete, grab-and-go system for Hydrogen-alpha viewing will appreciate the included accessories. Buyers who need a general-purpose night-sky telescope or a simple white-light solar filter should consider other instruments. The package is tailored specifically for H-alpha solar work.

0.55Å bandpass H-alpha filter

The Etalon filter provides a bandpass of less than 0.55Å, which determines the contrast and detail visible in solar prominences and chromospheric structure. This narrow passband is the critical specification that defines the telescope's solar performance capability.

Questions about this item

Will the 76mm aperture and V-style dovetail let me mount this Heliostar on my existing equatorial mount?

The V-style dovetail fits standard Vixen-compatible saddles, so the 76mm tube can be clamped onto most equatorial mounts that accept that profile.

How do I confirm the H-alpha filter is centred and the 11.5mm blocking filter is seated correctly after first light?

Centre the Sun with the Heliostar solar finder, then use the dual-speed Crayford focuser to sharpen granulation; a uniform, deep-red disc with visible prominences at the limb shows the .55A bandpass is aligned.

Which accessories ship in the rugged carrying case and what must I supply myself?

The case holds mounting rings, V-style dovetail, Heliostar solar finder, dual-speed Crayford focuser, 11.5mm blocking filter, clip-on sunshade, 20mm 70-degree 1.25" eyepiece and camera phone adapter; you provide the mount and tripod.
