Helmut Wimmer Astrological Cyanotype Print c.1957 Workbenches hand painted wooden project siteABOUT Original astrological cyanotype print by Helmut Wimmer, staff artist for the Hayden Planetarium, circa 1957. Cynaotypes will not fade in the sunlight due to the process in which they are produced. Both were professionally framed in matte black frame. Cyanotype is a photographic printing process that produces a cyan blue print. Engineers used the process well into the 20th century as a simple and low cost process to produce copies of drawings,
