1.
Select Solar System Align from the alignment options.
2.
Press ENTER to accept the time/site information displayed on the display, or wait until the telescope has
downloaded the information from the GPS satellites.
3.
The SELECT OBJECT message will appear in the top row of the display. Use the Up and Down scroll keys (10) to
select the daytime object (planet, moon or sun) you wish to align. Press ENTER.
4.
CPC then asks you to center in the eyepiece the alignment object you selected. Use the direction arrow buttons to
slew the telescope to the alignment object and carefully center it in the finderscope. Press ENTER when centered.
5.
Then, center the object in the eyepiece and press ALIGN.
Once in position, the CPC will model the sky based on this information and display Alignment Successful.
For safety purposes, the Sun will not be displayed in any of the hand control's customer object lists unless it is
enabled from the Utilities Menu. To allow the Sun to be displayed on the hand control, do the following:

EQ North and EQ South Alignments assist the user in aligning the telescope when polar aligned on an optional equatorial
wedge. Similar to the Altazimuth alignments described earlier, the EQ alignments gives you the choice of performing an
AutoAlign, Two-Star alignment, One-Star alignment or Solar System alignment.
EQ AutoAlign
The EQ AutoAlign uses all the same time/site information as the Alt-Az alignments, however it also requires you to position
the tube so that the altitude index markers are aligned (see figure 4-2), and then rotate the telescope base until the tube is
pointed towards the Meridian (see figure 4-3). Based on this information the CPC will automatically slew to two selected
alignment stars to be centered and aligned. To use EQ Auto-Align:
1.
Select EQ North or South Align from the alignment options and press ENTER
2.
Press ENTER to accept the time/site information displayed on the display, or wait until the telescope has
downloaded the information from the GPS satellites.
3.
Select EQ AutoAlign method and press ENTER
4.
Use the up and down arrow buttons to move the telescope tube upwards until the altitude index markers are
aligned. The altitude index markers are located at the top of the fork arm. See figure 4-2.
5.
Use the left and right arrow buttons to move the telescope base until the fork arms are horizontally parallel and the
tube is pointing towards the Meridian.
6.
Based on this information, the CPC will automatically display the most suitable alignment stars that are above the
horizon. Press ENTER to automatically slew the telescope to the displayed star. If for some reason you do not
wish to select one of these stars (perhaps it is behind a tree or building), you can either:
Press the UNDO button to display the next most suitable star for alignment.
Use the UP and DOWN scroll buttons to manually select any star you wish from the entire list of available
stars.
7.
CPC then asks you to center in the eyepiece the alignment object you selected.
Use the direction arrow buttons to slew the telescope to the alignment object and
carefully center it in the finderscope. Press ENTER when centered.
8.
Then, center the object in the eyepiece and press ALIGN.
9.
Once you press the ALIGN button the telescope will automatically slew to a
second alignment star. Repeat steps 6 and 7 to complete alignment.
