Star gazing for the blind.

Astronomy is a very visual pastime or vocation, so can a blind or partially sighted person really get involved in studying the skies and galaxies?

RNIB Connect Radio's Iain Wilson spoke to Dr Nick Bonne to find out how this can be the case by using technology and a little bit of belief.
