| The Epping 4m telescope |
| Yesterday's ADAP described the Epping 4m diameter telescopes, used in the 1970s and 1980s for observations of carbon monoxide in the 3mm wavelength band. Today's ADAP shows the telescope on the Marsfield site in 1981, with Dick Manchester and Robina Otrupcek discussing progress. |
