9. Repeat steps 7 and 8 until
F
Octantis and
P
Octantis appear properly positioned in their respective gaps.
F
Octantis will be off-center in its gap, as shown in the diagram, but
P
Octantis should be relatively centered.
10.Two additional stars on the other side of the pole have been added to this reticle: SAO258460 and
SAO258586. Use them to fine tune your alignment. Again, you may need to turn off the reticle to spot
these stars initially. The diagrams on page 8 show the positions of all 4 alignment stars for the reticle's
4 epochs.
11.Disconnect power from the illuminator, remove the polar axis scope, if you wish, and observe!

This diagram shows only the reticle lines used for Southern Hemisphere alignment. The 2 sets of lines for
P
Octantis represent
the Epochs 2005 and 2030. The 4 sets of lines for SAO258460 and SAO258586 represent the Epochs 2005, 2010, 2020 and 2030.
The gap in the longest line is for 2020, the 2 gaps on the 2 segments counter-clockwise are for 2010 and 2005,
and the remaining gap clockwise is for 2030. The stars are diagramed in their Epoch 2010 positions.
