Turbulent morning at Rozhen Observatory
This three image mosaic shows the area around the Solar tower at NAO Rozhen. At the left of the tower lightnings illuminate the adjacent clouds. The Moon (behind clouds) and the Pleiades are seen between the trees, Jupiter is the brightest object to the right. In the bottom right is my 12 inch ASA astrograph taking deep sky exposures (at this conditions :)).
