We will offer an opportunity for camera timing tests with the NEXTA (New EXposure Timing Analyser), reaching 0.1 ms accuracy, developed in our institute – Kamiński et al. 2023: https://arxiv.org/abs/2301.06378). Interested participants can bring their GPS-loaded cameras used for occultation observing. There will be a measuring station available in the main room.
