Visibility III / V
I guess this is already a tradition for me to take a picture of the atmosphere when I observe it. May Day night was spent with three telescopes. With Vespera I photographed Joutnen's targets, with eVscope scientific observations (Supernova alert and one asteroid), Dwarf II testing and searching for adjustments.
The second picture is an enlargement of the line of the landscape star picture, which I wonder what the object is when the colors stand out in the line. It wasn't an airplane because I was looking at the same area when I photographed. The exposure time was four minutes.
