Also in saying this the difference with supplied peices, i have read in alot of places that the cheaper eyepeices that don't use the ED glass arnt that great. My current telescope was given to me and its a 100 dollar dikies special! when i got it the collimnation was up the creek the thing had back lash like a car crash victim and to boot the cover for the OTA was never put in place hence there was a layer of dust that could rival the best attic's! :S So i want something that is going to be.... Good not just alright! ive suffered enough

Hi,
The GSO's also use a 10:1 crayford focusser. It used to be an option but now i think they include it in the price. As far as eyepieces are concerned whether you buy a GSO or a Skywatcher you are paying for the scope and they are essentially giving away the eyepieces; GSO or Skywatcher the eyepieces are equally good or bad
. Whenever you buy your first decent eyepiece it will perform better than the ones that came with the scope.
You will need to learn to collimate so the original state of the collimation is irrelevant, as is the dust. Your only relevant concern is the Pyrex mirror blank. If you think that is a good enough reason then pay the extra 250 AUD? for the skywatcher.
Cheers
