This is another lab I am writing long after the fact. This lab was written on 9/27/2024. This specific night, we took out the C11. We planned on sighting the Moon and Saturn. I don't have much to add, so let me just add the pictures below.

This picture wasn't taken with any kind of eyepiece or reducer. As we took this picture, we began to get dew collection on the front corrector lens. One thing to note is the red and blue hue on opposite sides of the moon. This is caused by the atmosphere. Something to help fix this is called an atmospheric dispersion corrector. It is two prisms that help correct the separated light from the moon. This light is separated because different wavelengths of light will travel through mediums (the atmosphere) at different speeds, thus we get the hues.

This image was taken with heavy fog on the front corrector and no eyepiece or reducer. This image is cropped in. Yet again the hues on opposite sides of the planet can be seen. On a clear, dry night, I want to try lens projection on different planets, but as magnification increase, atmospheric turbulence will also be magnified. This is an issue for another time. Considering the circumstances, this photo came out alright.
