Some considerable months have now passed, and interest has been rekindled. With the helpful assistance and advice of other IIS members from Canberra and Sydney, I have now opted for the more sensible and balanced version of a 10" SCT rather than the Newt, thus negating the risk of falling off stepladders when I've turned 80 and also having the joy of building a smaller obsy. My thanks to those people, and everybody else who has offered their learned opinions and prevented expensive mistakes. Motors to be mounted by the end of the month and hopefully all systems proven!
