Visibility IV / V

After noticing the cooler air on the balcony, enjoying a hint of illuminated night clouds, I just took my camera and tripod with me and went out to see if it was worth going out to take pictures. After all, there the sky looked so not when to go.

At the time the main picture of the observation was taken, there were surprisingly "crumbly" or turbulent-looking night clouds. I also took a wide-angle shot as a friend with a short time lapse of a hundred miles, when I had never tried it before for the illuminating night clouds myself. It turned out to be a surprisingly fun look, so you should try it again, with a little more pictures!
