StellarVision Seestar will detect the Level error when the user enters the shooting mode, if the error is too large, it will hint the user to adjust it, if the level is fine, it won't hint that.
And there are two specific situations, it won't detect the level.
1 For Scenery mode, the Level adjustment is unnecessary, so it won't hint it.
2 For Stargazing mode, when you disable the 'skip horizontal calibration'. it will not detect the level sensor, because it will auto-correct the level error after horizontal calibration.
