As Daniel said , Ronnie the cheeper non focus binoculars are ok for terrestial viewing but to look at the stars , moom etc you need exact focus to see these at their best , and they will give your eyes a real work out ( headache ) trying to compensate for the slight out of focus.
If thats all you have dont be afraid to use them to learn a bit of the night sky .
Also the Senier , Zeiss and others are in the 2000 dollar bracket so most of us can only dream .

. They are beautiful but for that price you would get a very , very nice Telescope .
