Finding objects on scene

I know this will sound wierd, but i'm total newbie in Unity. When i opened second Scene(that i was preparing for Loading screen) and after that changed back to my Scene 1 where the game is actually at camera moved away from my object. Camera which is connected to moving character was still there, but preview in scene was moved, and now i can't find my objects to continue working on scene. I found it once using wireframe, but when i was setting camera(rotating) i got moved away again. Now i can't find them. Is there any way to move my preview view on object or something to get back to scene? Or just to set my preview camera to coordinates?

Thanks for your answer!
