You probably purchased a Saxon / Sky Watcher Dob (Synta).
Finder Scope: loosen the locking ring and turn the objective lens housing until you achieve focus on a distant object during the day. Tighten the locking ring and you should be right. You can repeat the process at night to fine tune the focus for the stars.
Focuser: If your 2" adaptor is in place remove it and replace it with the 1.25" adaptor. Position your eyepiece and you should be able to achieve focus.
Align the finder scope to the view given in your eyepiece during the day. Fine tune this at night on a bright star.
I have made some assumptions about your telescope. Hope this helps.
