Thanks again for the tips.
At this stage, I will limit the star gazing to 10 adults and 10 kids with two volunteers. I am currently seeking permission from the school to access the school oval and run a couple of extension cords from the school gym.
I will need to borrow a dob from someone in Melbourne is due course (prob Oct/Nov time) and maybe a couple of cheapie EPs.
I will set up my laptop with a webcam feed from my 8" SCT. May also look at a motorised EQ mount (3 and above?) for my ED80, I think 3 scopes should be enough

Cheers,
Bo
