// TSX providing the star to use. the temperature at that time is recorded.

// is more than a degree celsius different from the last @autofocus2 time.
// if so, @autofocus2 is called again, although the telescope is not slewed. And so on.

// side of the meridian can be choosen and the mount will flip trying to get to it
// and, if using a dome, the slew does not wait for the dome slit to catch up (CLS flaw)
// so not only will an exception be thrown (Dome command in progress Error 125) the first image
// will be crap and the focus fail (as of DB 11360). So, this method will point the mount to a
// altitude that is no more than 80 degrees at the same azimuth of the current position in order
// to avoid a flip and subsequent bullshit happening
