Sorry for a basic question but when they used the transit of venus in the 17 hundreds to determine the value of the AU was this in miles as every reference I have seen always gives the value of the AU in Kilometers but I wonder if it must have been in miles.

Secondly I have looked at Stellarium to find the position where Venus will enter the sun as viewed from Brisbane as our school kids will be imaging this and I would like to know where to point the c8 so we can capture this.

thanks
