San José Observatory

Fitted in the center of the block comprising San José school and the Church of Our Lady is Balvanera Observatory Tower, at the top stands the dome swivel with 5 meters in diameter houses; it is the main instrument of the Observatory.

The equatorial telescope, manufactured by Raymond Augustin Mailhat, is the main instrument of the San José Observatory. The telescope is a refractor astro-chart of 1990 mm focal length of 127 mm opening in each tube, the original system of weights and watch Watt regulator was replaced by an electric synchronous motor for easy tracking of the stars The original eye missing, they were replaced by modern Meade eyepieces of different focal lengths. The origin of this instrument is French and was delivered to the centre as a donation by Mr. Sinforozo Molina, parent of a student in the early twentieth century The German-type equatorial mount supports two twins one tubes suitable for visual observation and one for photography, the latter had a mechanical tube for making glass photographic plates currently in the room old instruments because it was replaced by a modern CCD camera During the subsequent amendments that were made to keep using the old telescope sought to minimize the impact of the change being able to maintain the original look of this unique instrument.

It has an S-Big ST7 camera that associated equatorial lower instruments or photographic lens allows observation multitask as astronomical photography and supernova search

Old altazimuth refractor used for basic education

The room under the dome to dictate the various courses of astronomy, with a capacity for 20 people it is equipped with various media and tools built demonstration by members of the observatory that allow virtually experience the various astronomical phenomena

In it are preserved many instruments used in astronomical research and teaching, they were restored and classified over the years by members of the Observatory Currently you can see also web OSJ Antiguos Instrumentos

Also officiating as usual meeting room, the workshop is repaired where most instruments are prepared and samples classes open to the public, as well as new instruments to be used in demo them.

Throughout the year various courses are offered in the concurrent participating can go to get a thorough idea of how the universe is made, the means of observation and adventure meant for man to unravel the mysteries of the cosmos The aim is to achieve a theoretical-practical observations each topic bound to chords astromomicas ephemeris time.
