Jupiter and its satellites under adverse weather

Europa - Ganymede - Jupiter - Io - Callisto on June 10, 2016
Yesterday's sky was full of light clouds that became thicker as times passed. It was just enough see very bright stars and planets, so I decided to check how large the planets would appear with my old Tamron 270mm lens on my Sony A5000 camera. Jupiter came out to be about 11 pixels wide, or about 3.3 arc seconds per pixel. I then attached the camera to the telescope and saw that the planet was about 64 pixel wide, or about 0.56 arc seconds per pixel. This is more or less in line with the 1500mm focal length.
Since Jupiter was still somewhat "photographable" even with the cloud cover, I decided to take some more photos and stacked them to produce this nice result with all four Galilean satellites in view. The last time I took a photo like this was three years ago.
