Smart telescope company Unistellar has unveiled new technology to fight light pollution as well as a new solar filter for observing the sun. 

Available now as a firmware update for all Unistellar products – the eVscope, eVscope 2, eQuinox and eQuinox 2 – the new Deep Dark Technology is an attempt to automatically eliminate interference caused by city lights even in very bright urban areas to create black backgrounds to celestial objects.  A recent international study revealed that sky brightness is increasing in the US and Europe by an average of 10% per year, making observing faint objects such as nebulae and galaxies much more difficult using optical telescopes.
