A screencast is a digital recording of computer screen output (or video screen capture), together with spoken instructions, that demonstrates how to perform tasks using a particular piece of software, such as the NSO's Go Observing system.
We now host all of our videos, including screencasts, on our YouTube channel. Here you will find a range of "how to" videos based around using Go Observing and LTImage, as well as other interesting content such as astronaut interviews and "Ask an Astronomer" answers.
