Group 70

Group 70 is a non-profit educational organization comprised of people from many countries all around the world and many walks of life seeking to make the beauty of astronomy available to the peoples of the world. They began in 1988 with the goal of building a Large amateur telescope, a 70" astronomical instrument. Upon completion it would be the Largest telescope in the world built by and for those who do not have access to large institution-run observatories. Beyond building a large aperture telescope, they offer related instrumentation and services to those in amateur, professional and educational fields of astronomy.
