If you have a computerised mount that can slew quickly enough, and can interface to an app such as SkySafari which has a satellite database, and which can control the mount, it is possible to visually track some satellites by choosing it as your target in SkySafari, and then repeatedly tapping the "GoTo" button. In this way, the mount will keep slewing at its highest speed to a moving target.
Start with the telescope pointing in advance to where you will start tracking the satellite when it appears, so you don't have to slew across the whole sky just to be in the right vicinity. Use your widest angle eyepiece until you master the art - it can take a bit of practice to get the tapping timing working well.
EDIT:
I see from your subsequent post that you have an unpowered Dob - that makes it a LOT trickier! You could try using a "PushTo" app such as SkEye to help align your scope to be in the right location when it appears, but I guess you would have to move the telescope manually to keep it in view.
