In some cases you may want to override this procedure. If so, here is how to use the CHANGE option in the ALIGN

Arcturus.

SKY - One Star Alignment
A one star alignment is a rough way to align the telescope to the sky so it will track in the Alt-Az configuration. The idea
is to align to an object, wait for 5 to 10 minutes, then align to the object again. This is useful for situations when few stars
are visible, like just after sunset. This is also useful if you want to do some Alt-Az solar observing. The only object to
align to would be the Sun. This method gives you a rough sky alignment. This alignment is good enough to track in Alt-
Az, but may not be very good for pointing accuracy.

Move the telescope to its downstop
positions in both Alt and Az.
