This is an altitude chart showing the altitude of the target above the horizon vs. local sidereal time as the blue line. The two red vertical lines show the observing limits of the telescope. These charts are designed to mimic the altitude charts created by http://catserver.ing.iac.es/staralt/ but currently lacks much of the same functionality. If you want to create a night specific altitude chart for multiple objects, or want to see airmass, I recommend you use http://catserver.ing.iac.es/staralt/
