Figure 26: Rotating the Altitude Adjuster in the direction of the green arrow lowers the axis.
To adjust the altitude of the polar axis:
1. Loosen the both Altitude Adjuster Thrust Knobs (page 60).
2. Grasp and rotate the large central knob (near the green arrow in Figure 26) to raise or lower the
polar axis. The threads are right handed, so, when using your right hand, your thumb will point
up or down based on the direction of rotation (which follows the natural bend of your fingers).
See page 63 for details on how to adjust the polar axis to get "close" to the pole.
Altitude Adjuster Vernier Scale
In addition to the Altitude Scale tic marks on the wedge, the Altitude Adjuster knob has a fine-position
Vernier scale that allows the mount's elevation to be adjusted to an accuracy of plus or minus 15
arcseconds (Figure 27.)
So, for example, when the TPoint Add On's Polar Alignment Report states "raise the mount's polar axis
62 arcminutes," it means that one complete revolution of the Altitude Adjuster, plus two positive tic
marks on the Vernier scale from the vertical line labeled A should place the elevation of the mount very
close to the refracted pole.
The arrow on Figure 27 shows the location of the fine-position Vernier scale. This scale shows elevation
adjustments from +10 to –10 arcminutes. The medium height tick marks represent 5 degree divisions ,
the small tic marks represent 1 arcminute divisions. One rotation of the Altitude Adjuster knob equals
just about one degree of elevation adjustment . The rotating knob cover directly beneath the Vernier
scale has four vertical lines labeled with the letters A, B, C and D that can be used to make absolute
elevation adjustments.
