Meade Instruments Corporation - Meade LX200 Instruction Manuals a. If the star drifts South (or down), the telescope's polar axis is pointing too far East ( Fig. 22 ) b. If the star drifts North (or up), the telescope's polar axis is pointing too far West ( Fig.
Meade Instruments Corporation - Meade LX200 Instruction Manuals based on your observations above. Again, track the star for a period of time to be certain that Declination drift has ceased. The above procedure results in very accurate polar alignment, and minimizes the need for tracking corrections during astrophotography.
