G,day Peter
Welcome to IIS
Where in Perth do you live ?
The Lightbridge and GSO Dob's both share the same optics. If you plan on travelling to dark sky sights a
lot go for the lightbridge, but if like me you do most of your observing at home the GSO is the goods at a cheaper price.
The GSO eyepieces are OK but I would try to do a deal for something better. I have a drawer full of supplied-with-telescope eyepieces I never use.
I personally prefer to use the traditional finderscope that is supplied with with the GSO as it is easy to use with a good star atlas like Uranometria to find faint and obscure objects.
I hope I have been of some assistance
Mick.
