To get a better look at the Sun this summer, there’s no better way than with a dedicated solar telescope.

With one of these, you’ll reveal detail on the surface of our star in complete safety.

Their precision optics will unveil the giant, 1.4km diameter ball of helium and hydrogen at the centre of our Solar System as a body riven with activity – driven by nuclear fusion, seething plasma and interwoven magnetic fields.

Thanks to the etalon at the heart of a solar telescope, you can home in on an exact wavelength of light given off by excited hydrogen atoms, known as hydrogen-alpha.

This light comes from a layer in the Sun’s atmosphere that’s above the visible surface, called the chromosphere.

The familiar view of the Sun is transformed with a solar scope: it appears darker, with active regions marked by brilliants swirls of hydrogen.

Bright filaments and prominences of hydrogen float above the chromosphere, and with luck you’ll witness the vast release of magnetic tension in a powerful solar flare.

Uncover this world of visual excitement with one of the solar scopes in the guide.

Altair Astro

The Altair Sabre Alt-Azimuth Mount is a different take on modern telescope mounts.

There are no electronics, and no buttons to press.

One simply loosens the clutch-knobs, and points the telescope at the target.

By partially tightening the clutches, a smooth dampened motion makes observing a pleasure, even at relatively high powers.

Designed for those who want a manual mount to explore the heavens at night, daytime solar observing, or even terrestrial observation at high powers.

Up to two telescopes can be mounted together with a variety of optional Altair TMS 3” wide or 1.75” narrow format dovetail clamps.

The Sabre-AZ fits most astro-tripods on the market, and if you have a larger scope, there’s an optional stainless steel counterweight bar which fits most counterweights too.
