Question

 void Update()
 
     {
         Vector2 direction = Camera.main.ScreenToWorldPoint (Input.mousePosition) - transform.position;
         float angle = Mathf.Atan2 (direction.y, direction.x) * Mathf.Rad2Deg;
         Quaternion rotation = Quaternion.AngleAxis (angle, Vector2.up);
         transform.rotation = Quaternion.Slerp (transform.rotation, rotation, 3 * Time.deltaTime);
     }

Is the crosshair a custom cursor? In that case, you might need to set the hotspot of the cursor sprite to the center of the image, because (if I remember correctly) (0, 0) of the cursor is the upper left corner. You can even do it from code, see this answer.
