Hi Gary, and congrats on your purchase! Not being able to wait a month.. been there done that
It's great that you're starting with binoculars and a star chart, it will definitely help you find what you want to view when the scope arrives.
There's a tonne of mods you can do to the 8" dob, most of them you'll find on the IceInSpace site or here on the forums. But definitely you'll need to get collimation sorted, so you should get a chesire/sight-tool combo as soon possible, as well as a 2x barlow. What eyepieces did you get with the scope?
Being from newcastle, you should catch up with Orion, h0ughy and the other novacastrians at the NAS, and also come down to our central coast observing nights. You'll learn HEAPS that way, and also get to look through some other scopes and eyepieces.. it's a good way to see the money drain out of your wallet
Also thanks for the feedback about the site.. Apprecaite it!
