The sun in H-alpha, for a fraction of the usual price<\/strong><\/h2>\n\n\n\n

The Acuter Elite Phoenix 40<\/strong> brings H-alpha solar observation within reach. Where a white-light solar telescope is limited to sunspots, the Phoenix 40's 40mm front etalon reveals the dynamic chromosphere: prominences curling off the limb, dark filaments across the disk, and solar flares at active regions. The bandwidth of 0.6 Angstrom or better provides the contrast that makes these details visible.<\/p>\n\n\n\n

Pressure tuning and a spacious block filter<\/h4>\n\n\n\n

You adjust the etalon using pressure tuning: by regulating the pressure, the aperture slides precisely over the H-alpha line, uniformly across the entire image. The block filter has an 8 mm aperture, which is wider than usual for this class, providing a noticeably larger field of view both visually and when using smartphones or cameras.<\/p>\n\n\n\n

Zoom ocular and smartphone adapter included<\/h4>\n\n\n\n

The included 5-16mm zoom eyepiece continuously switches between 25x and 80x magnification: from the full solar disk to a close-up of a prominence. With the universal smartphone adapter, you can immediately capture your observations. Via the mounting rail, you can attach the compact, lightweight tube to an azimuthal mount or a sturdy tripod.<\/p>\n\n\n\n

What you see with it<\/h4>\n\n\n\n

Prominences: gigantic loops of gas erupting from the sun's surface. Solar flares: powerful bursts of energy from active regions. And surface detail: granulation, plages, and fine structures around sunspots, which change from day to day and sometimes hour to hour.<\/p>\n\n\n\n
