Nice video, I'm retired from merchant marine, but teach ratings the basics of navigation

Good day, Before anything, I would like to thank you for uploading on the Internet all the videos about navigation. I have learned from them, they are very good. There's a question I would like to ask if possible...I read a lot of materials about Celestial Navigation and there's one thing that I could not understand. They're saying like this: "We're taking bearings to the Star","We're taking bearings to the Pole Star" or whatever the celestial body is. My question is how we could take bearings to one star using the alidade upon the Gyro repeater?? That star is supposed to be on the sky. Its not the same thing like taking bearing to a buoy or a beacon lying down on the horizon. Please explain this to me. Its very very important to me. Unfortunately, nobody have shown that to us. Just by the books but not practically which is way much important than reading. Thank you very much for your kind support. You are the best.
