Welcome Eternal
You'll have a great time with your SkyWatcher 8", like I do, when the weather clears. Summer is a great time to get excited about the night sky in Sydney - apart from the humidity and unstable weather patterns, but there you go. It gets better as you head for Autumn
If you're ever down in the south west, pack your scope and come to an MAS (Macarthur Astro. Soc.) night at the Oaks, or at our Belanglo Forest dark sky site. You'll have a ball and meet a great bunch of amateurs.
Cheers
Chris
