Setting up apparatus: To begin with I adjusted the ocular to get the image of the crosshairs into focus. The instructions in the lab manual say to adjust the focus of the telescope until the slit in the apparatus becomes visible, but this was difficult as I could not actually find an image of the slit at all.

Calibration of the Spectrometer:

To calibrate the instrument I noted the locations on the dial of the lines corresponding to Mercury.
