The activity is low. Anyway, this is a chance for me to practice solar imaging with this new LS80T. The focal length of the LS80T is 560mm. The CCD size of DMK 41 cannot capture full solar disc in one go. Therefore a drifting approach is needed. In order to align the full disc properly, one needs to select those alignment points which appear in the whole video. Otherwise misalignment or non-uniform brightness will be resulted.
