Product Description

In stock with fast insured shipping - The superb Sky-Watcher Heliostar-76Ha is a safe 76mm aperture solar telescope for the observation of active solar prominences and other solar details in the H-alpha band, boasting an exceptional performance of 0.5 Angstrom or better, this narrow bandwidth allows much better views of the Sun. The double stack performance of this design is superb using a single etalon.

Flares, Prominences and more
When viewing the Sun in the narrow H-alpha bandwidth, the observer is rewarded with thrilling, awe-inspiring real-time views of our nearest star in it's full fiery majesty, seething with activity, revealing exciting details such as solar flares, prominences, spicules, surface granularity, sun spots and more!

The Heliostar-76Ha uses multiple technologies to protect the human eye during solar observation, including an infrared thermal ray reflection film, a special filter to block heat, and a filter to block UV light from entering, blocking stray light that affects observation. It uses a combination of front and rear filters to allow only monochromatic light with a wavelength of 656.28 nanometres emitted by hydrogen atoms to pass through, whilst blocking other light of different wavelengths. This allows the observation of quite active prominences in the H-Alpha band.

Double Stack perfomance from a single Etalon
Sky-Watcher's Solis etalon technology allows the Heliostar-76Ha to achieve a 0.5A bandpass without the costly expense and complexity of a second etalon to achieve the same performance. This allows the observer to obtain detailed images of the solar disk right out of the box without any further expense. This technology also avoids the brightness lost in more complex double stack systems.

Safety
The Heliostar-76Ha conforms to and meets the transmission requirements of ISO 12312-2:2015 (Filters for the direct observation of the Sun). Always use in accordance with the instructions and exercise the utmost of caution when viewing the Sun..
