Grenfell Observatory 0.6 m telescope

Inside the 6-metre aluminum dome of the Grenfell Campus Observatory there is a precision-made reflecting telescope designed and built by DFM Engineering of Colorado. Its 61 cm (24") mirror has almost 10,000 times the light-gathering ability of the human eye. The faint light from distant objects such as galaxies can be collected in this "light-bucket", then focused through an eyepiece for direct viewing or into instruments for analysis.

The telescope is used primarily as a research and teaching resource for physics and astronomy faculty, staff and students, however community outreach programs are also an important part of its mandate. Public tours and observing nights are scheduled, as well as school daytime tours for nearby schools.  There is also the possibility of remote-observing programs for provincial schools, and astronomy and physics-themed "camps" for high school students - such as the SNAP camp for Level II students.

The telescope is fully computer-controlled with tracking motors on an equatorial mount to compensate for the motion of the Earth, allowing it to maintain objects in its field of view. Within the dome, an 11 cm refracting telescope and articulated relay eyepiece (ARE) can accommodate the viewing public of all sizes and abilities.

A small Coranado solar telescope, piggybacked on the main telescope, allows safe viewing of the Sun during the daytime. Sunspots and beautiful prominences along the Sun's limb are revealed through its special solar filter.

Third-quarter MoonA separate "warm room" allows researchers to point the telescope and control its instruments - such as the high-performance Apogee U6 fan-cooled CCD imager and a Shelyak LISA high luminosity spectrograph - from relative comfort.

A display area in the vestibule of the observatory is open to the public during the day. Now in the display case:

"The Exploration of Mars"
"Juno - the next mission to Jupiter"

The astronomical research group at Grenfell use the telescope to study star clusters, short-period variable stars, and asteroids.

The telescope was installed in October of 2011 and was officially opened in May of 2012.  See how the observatory came together on our Building page.

The observatory is located at latitude N 48 deg 56 min and longitude W 57 deg 56 min.
