Reducing and Plotting Star Sights

In this video, we walk step by step through the process of reducing a star sight using strip forms and then plotting the results on a Universal Plotting Sheet. You’ll see how a raw sextant observation is turned into a usable line of position, from recording the sight to applying the necessary corrections and reductions. We then take that reduced sight and plot it correctly on a UPS to build an accurate star fix. This video is ideal for: Celestial navigation students Mariners preparing for exams Anyone learning or refreshing star sight reduction and plotting techniques Topics covered: Recording a star sight on strip forms Applying corrections and reductions Understanding intercept and azimuth Plotting lines of position on a Universal Plotting Sheet Building a reliable star fix Whether you’re new to celestial navigation or just need a refresher, this walkthrough shows the complete process in a practical, easy-to-follow way.
