Some of my favorite illustrations from the ‘Tony Jenzano: Astronaut Trainer’ book are now up on my website. www.benlinalexander.com
This one is a closeup of the Zeiss Mark II in action inside the planetarium dome. Before we had modern projectors, planetariums used these gigantic machines to project the stars onto the dome.
I’ve included a few historic photos of these amazing machines for more context.
