The drift method is the most accurate polar-alignment method and is suitable for high-precision imaging and telephoto systems.
The method:
No need for a North Star
Applicable to any region around the world.
Recommended:
Accuracy:
Highest
But it takes longer.
When the polar axes are not perfectly aligned:
The star will be in the field of view:
Slow drift
By observing the drift direction and adjusting:
Ultimately it can be achieved:
Precise polar alignment
Select:
Stars close to the celestial equator.
Requirements:
Moderate brightness
easy to observe
Use:
Long exposure or live view
Observe the stars:
Whether north-south drift occurs.
If drift occurs:
Adjustments:
Left and right directions (azimuth angle)
until the drift decreases.
Select:
Stars near the eastern or western horizon.
Observations:
Drift up and down.
by:
latitudeAdjustment knob
Adjustments:
until the drift disappears.
Repeat the above steps:
until:
The star drifts almost without drift.
Complete:
High-precision polar alignment.

Note:
This method takes a long time, but is extremely accurate and is a professional-grade alignment method.
