<H1>Some images taken through a solar spectroscope attached to the Ryerson 6-inch refractor</h1>
<P>Solar Spectra 

<P>February 28, 2002. 

<P>These images were taken through our solar spectroscope mounted on the six-inch refractor. A Canon digital
camera was mounted afocally on the output eyepiece of the spectroscope. These example images are, in order, H
and K calcium lines, hydrogen beta, the magnesium triplet, the sodium doublet, and finally hydrogen alpha (in
emission on the solar limb). There appears to be a instrumental artifact of repetitive lines in the H-alpha
image.
