The scope works fine for the most part but on occasion it seems to lose vertical tracking while shooting video and starts "searching" for the target (the Sun) moving the arm up and down but not horizontally. The Sun always stays within the field of view but it keeps moving significantly up and down. This continues until I stop the observation. When I restart it everything works fine and the Sun is solidly in the center. Sometimes the problem shows up multiple times per day (like during the eclipse) but it might not show up for weeks. The scope is on 2.61 firmware, standing on concrete and there is absolutely no wind.
