In the lower left corner you can see a group of stars which is called Pleiades ("Seulaset" in Finnish)
(M45). Some people in Finland call it
"Pikku Otava".
In the middle of the picture there is a thin horizontal white line which is probably a shooting star (tähdenlento).
A little bit left and up from the the line a dim reddish cloud is seen. The cloud is called California Nebula (NGC1499).
The details of the nebula and Pleiades are better seen in the corresponding larger image.
