3.1. Aligning procedure for the northern hemisphere:

The SynScan hand control and several applications running on PCs and mobile devices

can give Polaris orientation in the field of view of a polar scope depending on the

observer’s position and local time. Generally, the orientations are given in time format.

The reticle has a clock like engraving which is compatible with these applications.

For polar alignment, rotate the R.A. axis of the mount to put the 0 o’clock of the reticle at

the highest position in the field of view of the polar scope, then place the Polaris at the

correct clock position given by the SynScan hand control or other applications. Placing

Polaris at the correct position in the polar scope must be done with the azimuth and

altitude adjustment controls

Polaris position also changes as time passes. The new reticle displays 3 circles to

represent Polaris’s orbit in year 2012, 2020 and 2028. It also gives sub-dials at 0, 3, 6,

and 9 o’clock position for year 2016, 2024 and 2032. An engraving labelled with the

above years is also displayed on the right of the field of view for memo purpose.

When doing polar alignment in Northern hemisphere, the user should put Polaris on the

correct circle corresponding to the present year for better alignment precision.

3.2. Aligning procedure for the southern hemisphere:

There is a 4-star pattern in the polar scope, which resembles the bucket of the Big Dipper.

In the Southern hemisphere,there is an Asterism in Octans, which has this shape. By

rotating the R.A. axis and by adjusting the altitude and azimuth of the mount, the four

stars in the Asterism can be placed in the circles in the Pole Finder. This procedure can

be somewhat difficult in the city because all four of these stars are fainter than the Big

Dipper in the northern hemisphere
