Sky-Watcher Heliostar 76mm H-Alpha Solar Telescope SolarQuest Mount Kit

SKU CH-7K3K-5GGHS

A 76mm H-alpha solar telescope with a motorised SolarQuest mount that automatically tracks the sun for extended viewing

  • 76mm aperture reveals prominences and granulation in H-alpha
  • Bandpass below 0.55 Angstrom delivers high-contrast surface detail
  • Dual-speed Crayford focuser provides precise sharpness control
  • SolarQuest mount tracks the sun automatically for long sessions
  • 20mm 70-degree 1.25 eyepiece and phone adapter included for imaging

Dedicated H-Alpha Solar Telescope

The Sky-Watcher Heliostar 76mm H-Alpha Solar Telescope is a dedicated Hydrogen-alpha instrument designed for observing solar prominences, filaments, granulation and active regions. It serves both novice and experienced astronomers seeking high-contrast views beyond standard white-light filters. The package includes the SolarQuest mount kit for automated tracking.

Passive Optics With Motorised Mount

The optical tube uses a fully multicoated 76mm aperture lens with a Less Than 0.55 Angstrom bandpass and operates without active cooling or fans. The SolarQuest mount provides motorised solar tracking to keep the sun centred during extended sessions, powered by optional AA batteries. No external power supply is required for the telescope itself.

Ready-To-Observe Accessory Bundle

Included mounting rings and a V-style dovetail allow immediate attachment to the SolarQuest mount. A dual-speed Crayford focuser, 11.5mm H-alpha blocking diagonal and Heliostar solar finder enable safe, precise targeting. A 20mm 70-degree 1.25" eyepiece, clip-on sunshade and camera phone adapter support visual observation and quick photo sharing, all stored in a rugged carrying case.

Questions about this item

How do I attach the 1.25" eyepiece and blocking diagonal so the 76mm H-alpha telescope tracks the sun correctly?

Insert the 11.5 mm blocking diagonal into the focuser drawtube, seat the 20 mm 70-degree 1.25" eyepiece into the diagonal, then secure the telescope to the SolarQuest mount using the supplied V-style dovetail and mounting rings before powering the mount with AA batteries for automatic solar tracking.

Which components will need cleaning or replacement after repeated solar sessions?

The multicoated H-alpha objective, the 11.5 mm blocking filter, and the 1.25" eyepiece surfaces should be cleaned with optical-grade solution and lint-free cloth when dust or pollen accumulates; the clip-on sunshade and solar finder may need replacement if their coatings degrade or the finder's alignment drifts.

At what point does the <0.55 Angstrom bandpass limit detail during long prominences observations?

The <0.55 Angstrom bandpass restricts contrast on very faint, high-velocity filaments during extended sessions, so fine plasma structure may become harder to resolve before the dual-speed Crayford focuser reaches its travel limit or the SolarQuest mount requires battery replacement.
