Hi Chrissy and
Shouldn't be too hard to get some exciting viewing out of that telescope. What are your problems exactly?
There are plenty of us in Melbourne who could have a look, show you how to set it up and point out some delights in the sky to observe. Just ask.
ps. It wouldn't have been much use on Comet McNaught - your eyes or some low power binoculars were all you needed.
pps. Guys, that tube is more like 700mm long, so it's going to have one of these 2x lenses built in, isn't it? Where do they put these - insider the focusser?
Cheers
Eric
