Sandra, once you get an object (star, planet, nebula etc) in focus, that is the exact correct position of the focus knob for your eye with that particular eyepiece. You can't alter the magnificaton with the focus knob.
To increase or decrease the magnification you must change eyepieces as pointed out by jjj.
You have a 25mm eyepiece that gives you a certain magnification. If you want to increase the magnification you need to remove the 25mm eyepiece from the holder and insert a smaller eyepiece. Maybe 10mm or what ever you have. When you change eyepieces you will have to re-focus for that eyepiece. Probably only a small adjustment.
You will notice that as you go smaller in eyepiece size (higher magnification) that it becomes a bit more fiddly to focus as your hand shakes the scope a bit and this is magnified by the higher power eyepiece. Get used to it.
A star will look just like a bright point of light when correctly focused. That is normal. Some stars that appear uninteresting to the naked eye will become multiple stars or perhaps a Gaseous Nebula when you look through the telescope. That is when the OH WOW factor comes in.
What eyepieces/accessories did you get with the telescope?
Keep the questions coming, you have a nice rig there.
