You can use it to make drawings of the sunspots. Sunspots will move on the solar disc due to the sun's rotation, so by repeated observations it is possible to determine the rotation speed of the sun.

The telescope has a fixed focus with a total length of 875 mm. The field of view is 0.75 degrees, or 1.5 solar diametres. The size of the solar image is about 85 mm. Altitud: 0 - 90 degrees.
