Greetings all, first time here, just wanted to share something that might be interesting.
It's doubtful anyone out there has used the star clock to get longitude. It seems God and I are the only ones who know about and approve this method. It is quite simple. Measure the LHA of a star directly on the sky. Combine the LHA with the stars' Right Ascension to get LST. Combine LST with GST to get longitude. This can be done All Night. Polaris is the pivot point to measure by, the center of the clock. If you catch a star ON your longitude, upper branch, that star's RA is your Local Sidereal Time. This is only a very brief description. If anyone is interested, an in depth description is available. What may scare many readers is the list of things not needed for this method. You will NOT need; sextant, sight reduction tables or forms, plotting sheets, DR, AP, EP positions, atmospheric refraction, altitude above sea level. It is amazing nobody seems to have figured this out before. Thank you and happy navigating.
