That's a great presentation you did. Pardon my lack of knowledge but can the Concise Sight Reduction be performed for all celestial bodies? I'll need to study your presentation since, so far as I know, it's the only one available on the web. Does anyone know if the USNO Almanac still has the Concise method in it? Heard a rumor they discontinued it.
Granted, you can get Hc in about 10 seconds using a calculator but it sure is a lot more enjoyable using paper and pencil as you demonstrate.

Thanks. I mostly wanted to help someone get started that (like me) might have trouble finding understandable literature on the subject.
"...can the Concise Sight Reduction be performed for all celestial bodies?"
There are differences (mostly the corrections) for the planets. With nav stars you are using the GHA of Aries and the SHA for the particular star you are sighting. The moon and Polaris are quite a bit different. One of these days I'll remake the video and try and correct the errors I made and get it a little shorter. Maybe I can work in the other bodies or make videos for them.
I used to be a normal person, then I discovered how to locate myself on this planet using a star.
