Your suggestions for implementing an 80% charge limit/manual charge control and dew heater battery consumption metrics have been recorded .when there is wind, ground vibrations, or other factors causing image trailing, or if there are too few stars in the field (fewer than 20 stars), the stacking may fail, and the system will automatically reject the frame and continue shooting. Please check whether you have successfully completed the sky-level calibration. (Advanced Feature - Initialization - Skip "Horizontal Calibration")
In Az/Alt mode, Seestar stacking failures are influenced by many factors, such as wind, ground vibrations, and other environmental conditions.
If the target you are imaging is near the zenith (over 85 degrees), field rotation will be more significant, which can also increase the likelihood of stacking failure.
It is recommended to use the default 10-second exposure time, as longer exposure times are more likely to cause star trailing.
Lastly, please check the level of your equipment to ensure proper alignment.
