Hi folks 2 questions to pose:Most nav texts discuss lower and upper limb obs but the "swinging the arc" diagrams and explanations only pertain to lower limb. I probably am missing something obvious but can you folks describe the upper limb "swinging the arc"procedure, i.e., point of tangency, etc? In this day and age of computer generated animations I have only been able to find a very limited no.of cel nav videos, namely Mr. Buckley's and a Magic Lamp one and about 40 dollars price. They are very well presented but limited to solar obs( probably lower limb obs!). It would be pretty cool to see lunar distance, interstellar angles, twilight star and planet obs in video presentation. If anyone has info on this it would be greatly appreciated. Thanks much.
