This is a troubleshooting time lapse video of a Sunobserver eADC showing the front prism recorded over 104 minutes at a constant altitude of 17.39 degrees fixed to a photo tripod. The compensation parameter is 1 and the tilt parameter is zero. The front prism rotates clockwise about 90 degrees total when it should not be moving because the altitude is not changing. This direction is such that the compensation is continually being reduced despite the altitude not changing. This matches the behavior seen when imaging the planets, where the initial good image rapidly degrades to bad color fringing. The rear prism does not rotate, which is correct. The video frames are timestamped at the top.
