Hi all,
I have managed to acquire a 4inch newt, but the secondary mirror on inspection is well ... not in good shape (there is no mirror surface left!). It looks like the silver has blackened completely.
I was wondering how easy it is to re-collimate a scope once you've played with the secondary mirror, and where the best place to buy one would be.
I live on the south coast and don't make it to Sydney too often, so an online store would probably be ok.
Kind regards,
Matt.
