Remember to select alignment stars that are as far apart in the sky as possible. For best results make sure that the
third alignment star does not lie in a straight line between the first two stars. This may result in a failed alignment.

Don’t worry about confusing planets for stars when selecting alignment objects. SkyAlign works with the four
brightest planets (Venus, Jupiter, Saturn and Mars) as well as the Moon. In addition to the planets, the hand control
has over 80 bright alignment stars to choose from (down to 2.5 magnitude).

Rarely SkyAlign will not be able to determine what three alignment objects were centered. This sometime happens
when a bright planet or the Moon passes near one of the brighter stars. In situations like these it is best to try to avoid
aligning to either object if possible.

•
For the best possible pointing accuracy, always center the alignment stars using the same final movements as the
direction of the GoTo Approach (by default this will be using the up arrow button and the right arrow button).
Approaching the star from this direction when looking through the eyepiece will eliminate much of the backlash
between the gears and assure the most accurate alignment possible.

As with Sky Align, Auto Two-Star Align downloads all the necessary time/site information from orbiting GPS satellites.
Once this information is received, CPC will prompt you to slew the telescope and point at one known star in the sky. The
CPC now has all the information it needs to automatically choose a second star that will assure the best possible alignment.
Once selected the telescope will automatically slew to that second alignment star to complete the alignment. With the CPC
set up outside with all accessories attached and the tripod leveled, follow the steps below to align the telescope:
1.
