Suntoy was invited to the ScopeX Telescope and Astronomy Exhibition at The Military Museum in Johannesburg. We scattered our Consol Solar Jars with red LEDs along the perimeter of the museum's gardens and set the scene for an astronomers dream come true! Red light preserves night vision for astronomers as it is the only light that doesn’t adjust the retina or contract the pupil of the eye. Red light allows optimum telescopic vision for reading sky charts. The Consol Solar Jar is definitely an astronomers best friend!
