To conform to local use (principally European) use of a semi-colon (;) was allowed *as an extension of the standard* so that "1234,55678;" was equivalent to "1234.5678," later other delimiters were permitted. As far as I can see multiple non-comma delimiters of the same kind (eg ";;;;") have never been permitted. The spec appears to go back to IBM and OS360 and so if you read it in a historical context it is probably just what you would expect. Fascinating though!

This is fairly easy to do. First convert AltAz to Cartesian coordinates. This is a left handed coordinate system. The X? axis points North, and the Y axis points East. Then rotate clockwise around the Y axis by 90 - latitude and reverse the X and Y coordinates so that the X axis points South and the Y axis points West. You are now in the HADec coordinate system and the LHA ls the angle between the X and Y axes measured clockwise from the X axis.

I'm afraid that I led you astray by failing to notice the error in your logic. You do not, in fact, have the latitude unless the camera is pointing due South, in which case, as any navigator would tell you, the solution is trivial as the HA is zero. This is not anything that Astropy will help you with, but the way that I would go about solving the general case is to set up a spherical triangle with one vertex at the pole, the second at the zenith and the third at the point of observation. Then the knowns are the side between the zenith an the point of observation (90 - Alt), the side between the pole and the point of observation (90 - Dec) and the opposite angle at the zenith (Az). This triangle can then be solved to yield the side between the pole and the zenith (90 - lat) and the angle at the pole between the point of observation and the zenith (-HA). One other thing. Your equation for longitude is also wrong. You need the Greenwich Apparent Sidereal Time (GAST) rather than GMST there.
