42 cm Telescope

Public Observing

The telescope is open on Saturday evening, if the skies are clear. Graduate students and astronomers from the Department of Physics & Astronomy will show visitors many celestial sights that are above the horizon including the rings of Saturn, craters on the Moon, Jupiter's moons, star clusters, nebulae and galaxies; the objects shown on a given night varied with the seasons & the lunar phase.

The telescope will open on Saturday nights from approximately 1 hour after sunset and will remain open for about 3 hours. Although the open times change greatly, typical observing times in January run from ~6:00pm until 9:00 pm.  Typical summer hours are from ~9:00pm to midnight.  Those interested can call 822-6186 for recorded information, and people can find out if the telescope is open.

  NOTE : The telescope dome is not heated, so in the winter months people should dress warmly!

Atop the Earth & Ocean Sciences East building, we have a 42 cm telescope which is used for public observing, undergraduate teaching and instrument development. This instrument was obtained from Sigma Research with monies provided by the BC Science Council.

The Telescope :

German Equatorial mounting  As the accompanying diagram shows, the telescope is mounted with an equatorial German design with 2 focii.  

The Cassegrain focus is at f/13.5 and provides a field of 0.5 degrees. There is also a 4 mirror Coude train which brings the focus to the floor below at f/57. A focal reducer can change this to a speed of f/18.  
Location:  Latitude:   49° 15' 30'' N
Longitude:  123° 15' 24'' W
