In this picture, the mirror in its case is just below the telescope tube prior to being raised and attached to the telescope tube. Visible in the background are the two clocks used by observers.
A picture taken looking down the telescope tube after the primary mirror has been installed. The primary is visible through the partially open mirror cover.
The finished telescope pointing north. Note that the spectrograph is not attached to the back of the telescope. Visible in the background are the two clocks used by observers. One kept normal time, the other sidereal time. A calendar between the two…
A picture taken October 21, 1916 of members of the Victoria chapter of the Royal Astronomical Society of Canada (RASC). J.S. Plaskett invited the group to the observatory to see the completed telescope, minus the mirror, and marvel at its majesty.…
A picture of the spectrograph that J.S. Plaskett designed attached to the telescope. Plaskett paid attention to the details of the design to make it as efficient as possible. Visible in the background are the two clocks used by observers. One kept…
A picture of the spectrograph that J.S. Plaskett designed attached to the telescope. Plaskett paid attention to the details of the design to make it as efficient as possible. The spectrograph could be configured to give higher resolution spectra.…
A picture of the plateholder for taking photographic images at the Newtonian focus. While the Plaskett telescope primarily took spectra, it could be configured to take images.
A picture of the top-end of the telescope in the Newtonian configuration. In this mode the light returning from the primary mirroe was reflected to the side of the telescope tube where a camera was located that took photographs. The secondary mirror…
A picture of the temperature recording devices mounted inside the dome. It was important to track the temperature changes from day to night to understand how the telescope would perform.
A picture of the main electrical panel for the telescope and dome. The B.C. Electric railway rank by the bottom of Observatory Hill, and the 220 V DC from the railway was brought up the hill to power the observatory.
A picture of the completed telescope pointed east. The spectrograph is attached to the telescope. The mirror handling cart is visible as are the two clocks, one for standard time and one for sidereal time.
A picture of the telescope with an insulated blanket wrapped around the lower end of the telescope tube. The blanket was used to keep the mirror at a stable temperature. The glass uesed for the mirror was sensitive to temperature variations and the…
A picture of the completed telescope pointing o the south-east. J.S. Plaskett is standing on the observing floor near a control panel. The mirror handling cart is visible in the background. Visible in the background are the two clocks used by…
A picture of the dome finished except for the part that was left unfinished so that the telescope could be installed in the dome. Once the telescope was installed, the remainder of the steel structure and outer, and inner, panels were installed.
A picture of the completed dome with the shutters open. The man standing in front of the entrance is Thomas Tenant Hutchison. Hutchison would join the staff of the observatory when it began operation. He maintained the telescope and dome as well as…
A picture of the front of the office building completed in September 1924. Between 1918 and 1924, the staff had to work on the ground floor of the telescope
A picture of the west side of the office building completed in September 1924. Between 1918 and 1924, the staff had to work on the ground floor of the telescope

A picture taken on the occasion of the official opening of the observatory in June, 1918. Left to right are Ambrose Swasey, William Wallace Campbell, Director of the Lick Observatory, John Stanley Plaskett, and Ambrose Swasey.
A picture of the mirror blank in John Brashear's workshop before work started on figuring and polishing it to the correct shape. The mirror blank was shipped from Belgium just a few days before the start of WW I.

A picure of the mirror blank set up on the grinding table in Brashear's Pittsburgh workshop. Brashear appears ready for work, wearing his apron and a peaked cap.
A picture of the figured mirror in Brashear's workshop. The calendar shows the month as November, 1915. We don't know if this is the month the image was taken.
A picture of a early wooden model of the telescope and part of the dome structure. This is likely sitting in the offices of the Warner & Swasey Co. who built the telescope.
A picture of the lower half of the 1/10th scale model of the telescope and dome that was built by Warner & Swasey. This is an excellent image of their workshop showing a series of lathes powered by leather belts all connecting back to the power…
A picture of the almost completed model of the telescope and dome. The telescope and dome could be moved. The telescope was moved by inserting a rod into the base of the telescope where it connected to the gears. This model was exhibited in the 1915…
