Thanks again Harry and Nathan, it's great to receive such experienced advice. I was likewise concerned about the risk of focal lengths shifting and will be sure to tape the zoom when using that, and to experiment also with primes. It's a case of thinking that the VR on the former might have some positive effect to stabilise the lens quickly as the gigapan moves each couple of seconds, vs the advantage of a sharp prime - but practice will tell. At this stage now I just wait to see if the budget is approved to buy the Gigapan, not least because there is interest from other quarters in providing Gigapan shots for related educational / museum institutions. I think the scope of this machine extraordinary. Best, Jethro
ps. I greatly enjoyed your accounts of public curiosity in what you were shooting. I suppose this is inevitable when you take a piece of NASA technology out into the wild yonder!
POSTCRIPT: have just been given approval to purchase the Gigapan for our school, links to photos will follow once we have learned how to use it! Thanks for all your help.
