French digital telescopes give stargazers nasa-quality view of space

French digital telescopes are shaking up astronomy by giving amateur stargazers access to equipment previously limited to universities and large scientific institutions. Made by Marseille

firm Unistellar, they have even been credited with a scientific discovery by the journal _Nature_. USERS INVOLVED IN NASA RESEARCH Unistellar co-founder Laurent Marfisi told _The Connexion_:

“Because our telescopes are digital, the information can be shared over the internet, which means data from many different locations can be collated to discover things that might otherwise

not be seen. “For example, when Nasa recently crashed a spacecraft into an asteroid to see if its trajectory could be moved, there were at least five main scientific inquiries. “One had a

university researcher coordinating a team of 31 of our users. They were not only the first to publish pictures of the collision, but by keeping their telescopes trained on the site for a

month, they also gathered valuable data about the dust cloud thrown up, how it dispersed, and the colour of the dust.” READ MORE: AMATEUR PHOTOGRAPHER’S SHOT OF DORDOGNE SKIES SPARKS NASA

INTEREST MAGNIFIES NIGHT SKY 100 TIMES MORE THAN TRADITIONAL MODELS The company launched in 2015 with the idea of using digital technology to make a reasonably priced telescope capable of

magnifying the night sky a hundred times more than traditional models. Thanks to partnerships with renowned scientific organisations, the firm also lets users become ‘citizen scientists’ and

contribute to cutting-edge research. “Suddenly it is possible to see stars in deep space and things such as nebulous clouds, which previously had only been seen in pictures from

professional telescopes in universities and places like Nasa,” said Mr Marfisi. “The electronic capturers in the telescope are much more sensitive than the human eye. They can also receive

light for longer than the human eye – for a couple of seconds – whereas the human eye registers light for just a millisecond.” READ MORE: PHOTOGRAPHER CAPTURES RARE ‘FLOATING’ MOON IN

SOUTH-EAST FRANCE SOFTWARE IDENTIFIES STARS AND PLANETS The cheaper model, called eQuinox2, costs €2,499 and does not have an eyepiece. Images are displayed either on a TV with an Apple TV

link, or on a mobile phone, tablet or laptop screen. A similar model, this time with an eyepiece developed with Japanese camera-maker Nikon, costs €4,499. “Most professional astronomers have

been used to working with screen images for a while now,” said Mr Marfisi. “But with an eyepiece you see and feel the infinity of space instead of a flat, two-dimensional image, which is

why we developed the eyepiece model.” Both models are linked to software that identifies objects in the viewfinder, allowing users to get optimum pictures of named stars or planets.

OPPORTUNITY TO JOIN ASTRONOMY PROJECTS The telescopes can be used in cities and other places where light pollution normally makes using one difficult. Unistellar also sells a filter enabling

users to look at the sun safely during the day. “It is our nearest star but we are still learning about it because it is so difficult to view,” said Mr Marfisi. The telescopes, and software

to run them, are designed in Marseille but made in China. Mr Marfisi said most buyers are moving on from cheaper optical telescopes, costing around €100, after realising the limitations of

their equipment. However, around 30% are novices buying their first telescope, who are attracted by the quality and the digital guides and sky maps that come with it. As well as the asteroid

community telescope project, Unistellar users can join a range of other collaborative astronomy projects. NIGHT SKY SMARTPHONE IMAGES FROM ANOTHER FRENCH FIRM Another French company,

Vaonis, is making a name for itself with smartphone and tablet-driven products described as a cross between a camera and traditional telescope. The firm, based near Montpellier, is due to

launch a low-cost model called Hestia in June, which can be pre-ordered for €177 from its website. It claims this new model will provide images of the sky on your smartphone with five times

the resolution and 25 times the magnification of most smartphone cameras. Its other telescopes start at €1,500. RELATED ARTICLES PHOTOGRAPHER CAPTURES RARE RED SPRITE LIGHTNING NEAR DORDOGNE
