Wow. The OP was, I believe, my first SDMB post that I spent any amount of time on. To see it pop up again out of nowhere is a trip. And who’s this Earthling guy, anyway? 
Bad Astronomer, I add you to the list of people that I genuinely thank for helping with the questions I had which prompted my OP – an OP which I still feel somewhat guilty about in that I really did not intend for people to invest precious time into answering my questions… not in this thread, anyway.
Actually, I’ve been to your wonderful site before, when it was referenced in this thread which was sparked by SDSTAFF David’s Was the Apollo moon landing a hoax? staff report. It’s a terrific website.
