Hi Alex,
Yup, I am trying to wangle some away time from home to go to Linden this weekend and bring my webcam etc.
Hope to see you there.
As for the other stuff, ummmm, dunno?
I think you need to "set" the starting point for the Azimuth one, say on aCrux and then jump to the next object by spinning it around just like an EQ mount. As for the Altitude protractor, i dont know how you reference that back to anything or "zero" it / set it off a star etc. The added issue here is the altitude of all objects changes as time goes by, so you need to keep correcting your numbers and points of reference.
Most forum entries about this state you can get the alt/az coords from star charts etc off the ra/dec using a laptop in realtime but none tell you how to start off by setting it up off a starting point.
I will have my borrowed laptop (pentium II running windows me and 64mb RAM - wooohoo) with me so if we set up near each other (and hold hands - woooooo!!) then I can call out the numbers to you off Cartes Du Ciel which is running on the laptop.
Sounds like a plan? (apart from the hand holding bit)
Cheers
Chris
