The stellar photometers of Harold L. Johnson, and the first years of the Mexican National Astronomical Observatory at San Pedro Mártir (2022)

unapi

The first observations made at the Mexican National Astronomical Observatory at San Pedro Mártir were stellar photometry carried out during February 1971. The first photometric instruments were those of Dr Harold L. Johnson or ones obtained for the National Autonomous University of Mexico by Professor Guillermo Haro, which were constructed according to designs of Dr Johnson. Over the next 10 to 15 years, most of the scientific output of this Observatory was produced using the 5-color and 13-color photometers. These photometers were phased out at the Observatory in the mid-1980s as more modern instruments arrived, but over the years they had been used by at least 16 principal observers to produce more than 56 publications in major international journals. Since the year 2000, eight pieces of equipment associated with these 'Johnson photometers' have been recovered and refurbished for an unofficial museum at the Institute of Astronomy in Ensenada, Baja California. The display comprises complete photometers, a partial single-channel and a two-channel photometer, an infrared photometer, cold boxes, a DC amplifier, an offset guider, and one instrument which has not yet been fully identified.
