(Get the code!)
May I designate your five results as (1) through (5) to make it easier to reference them? From what I can tell, here is what happened each time.
(1) You are printing out Polaris's position using today's coordinates (“epoch of today” is what a professional astronomer might call it) by saying “.ra” — but if you will double check the tutorial, it uses “.a_ra” which is the “astrometric position” which uses the sky coordinate system of the year 2000 as an unchanging standard. If you will change your own code to use this, then I think you will find that the results agree!
