9. The Star Chart Library
Every observatory needs a place for the nerd stuff, and this is mine. It’s a warm room with dark wood shelves, a big oak table, and maps and charts pinned to the walls using item frames. I made star charts out of maps I actually filled in, and hung them in rows so it looks like a real astronomer’s study. There’s a fireplace, a kettle on the campfire, and a window seat for reading while snow falls outside.
