You do not need an outside view to align on the cat.
For Cat 1, Put the nose on the center of the groove, roll slowly to the shoe, look out your right side for a reference point like the little hatch with the yellow caution marking and stop when your right shoulder is aligned with the aft end of it. This works every time for Cat 1. You can do the same thing with each Cat just find your reference point and train your eye.
You will get so good at it you will find yourself doing this perfectly and faster every time.
