Astronomy Notes (Nick Strobel)

Staralt
This program shows the observability of objects in various ways: either you can plot Altitude against time for a particular night, or plot the path of your objects across the sky for a particular night, or plot how Altitude changes over a year, or get a table with the best Observing Date for each object.
