Fahim - at last you've teleported to my planet (DX3) and thankfully left your darn watches stuck on 3pm back on Earth! (Did I ask you before whether they were 24 hour ones? - if they weren't that could well explain our previous differences; RA is a 24 hour model.....)
At last our fertile imaginations have synchronized (this could only occur on DX3) and would go so far as to say that we could substitute your "reference sphere around my dob" at the Pole (I'll let you pick which one, as you are a guest of mine on DX3) into an actual calibrated RA circle on my dob.
I think you will find that when we take my other dob (I have many) to the Equator we can give it a spin and you will find that any given Hour angle will intersect (or at least be directly below/corresponding to that specific Hour Angle on the dob at the Pole) twice in a single revolution of the dob mount at the Equator.
Again I will emphasize that this will be an absolutely arbitrary alignment (due to the altitude mount of the dob being centered directly above the azimuth pivot point it will afford us no ability to coordinate our scope onto anything -except to be able to claim that we could locate two points in the heavens at any particular RA.) Something akin to one of your damnable watches stuck on 3pm - they'll tell correct time twice a day, ie as long as they're not 24 hour ones......
Darryl - ps I'm about to start a new thread proposing Left Ascension and positive Declination for us Southern Hemisphere mobs - we've been kept upside down and on the bottom of the AA heap for far too long...
