Resumen
The semi-automatic measure of the photographic film from the declination circle, is based in the use of a lineal array of 512 photosensors, RETICON RL 512G. The corresponding hardware includes analog-digital conversor, a memory of 2 kb RAM, the electronic sinchronization and the necessary interface to control the system with a micro-computer Apple IIe. Lately, the information obtained, is sent to a PC Multitech, which process the data and gives the final results. Four reading, lasting 20 ms in total, are made for each picture: the error of a measure is ±0.02". The system does not need refrigeration. Asociación Argentina de Astronomía
