Part 2: Viewing the Sun

_DSC5699.jpg

In this section of the lab, you will observe the Sun using the Solar Telescope on VAO (pictured above) with a filter designed for viewing active features on the Sun's surface. The Coronados use an H alpha filter which only transmits red light from hydrogen gas.

WARNING:ааDO NOT MOVE THE TELESCOPE UNTIL YOUR TA GIVES APPROVAL!!!аENSURE ALL TELESCOPES OTHER THAN THE SOLAR TELESCOPE ARE COVERED BEFORE POINTING AT THE SUN!!! POINTING AN UNCOVERED TELESCOPE AT THE SUN WILL DESTROY THE TELESCOPE OPTICS AND CAMERA!!!

Exercise

1. Telescopes ususally concentrate the light from faint objects in the night sky. аWhat are the primary differences between observing the Sun and observing a faint star at night?


2.аTake an image of the sun using the solar telescope on VAO. аYou will then identify the features in your image in a similar fashion to Part 1.

3. How many of each feature from Part 1 do you observe with VAO?
