Please make sure to use a solar filter when observing the Sun, and ensure the environment is stable (no wind, no clouds, and no ground vibrations).
Before observing, tap "Level Sensor Calibration" in the app to calibrate the initial horizontal position. However, note that you need to remove Seestar from the tripod and place it on a relatively flat surface (such as a table or floor, the flatter the better) before performing the calibration. After that, calibrate the compass and select the corresponding mode to observe the target.
