General Information

Once the telescope is initially aligned with the eye, the key to fixing the polar alignment is measuring the alignment from the celestial sphere. Finding good stars can be a hassle, however. For initial star-finding, a TelRad attached to the OTA is essential.

This section is divided into information for TelRad alignment, the Two-Star Pointing method, Tpoint Pointing method, and finally tips on how to adjust the telescope polar alignment. A Two-Star model can be created much faster than a Tpoint model, which requires at least 4 or 5 stars.[check this!] The disadvantage of the Two-Star method is that it requires an external measurement of the telescope pole in encoder counts. Two ways to make this measurement are described in Section 5.2.3.
