2.2 Polar Alignment Using the SynScan Hand Controller

2.3 Polar Alignment with the Optional Polar Scope

PART II: POLAR ALIGNMENT

1. Choose 2-Star alignment or 3-Star alignment to align the mount, and then perform the po-

lar-alignment routine. Repeat these operations several times until the SynScan hand con-

troller reports small polar alignment error after the 2-Star alignment or 3-Star alignment.

Refer to SynScan hand controller’s manual for detail operation instruction.

2. At the end of the polar-alignment routine, tighten the primary locking knob, and then tight-

en the azimuth locking screws, the fork gripping knobs and screws. User should observe

the alignment star in the eyepiece while alternately tightening these symmetric knobs and

screws; try to minimize the movement of the alignment star in the eyepiece.

3. It is recommended to remove the jackscrew handle after the polar-alignment has nished.

It can prevent unexpected changes to the polar-alignment.

1. Install the polar scope assembly on the EQ8 mount as shown in Fig 2.3a.

2. Verify whether the polar scope is aligned with the R.A. Axis. (Refer to the upcoming sec-

tion “Align the Polar Scope”).

3. Find the orientation of Polaris in Polar Scope. (Refer to the upcoming section “Orientation

of Polaris in Polar Scope”).

4. Use the latitude jackscrew and the azimuth adjustment knobs to polar-align the mount:

• Fig 2.3b shows the pattern in the eld of view (FOV) of the polar scope. If the image

appears blurred, rotate the knurled ring of the polar scope’s eyepiece to focus.
