Hi Steven,

This link will show you how you can get started with collimating your scope, if you have an old film canister handy even better, until you get your hands on either a collimating eyepiece or a laser collimator. These are available from pretty much all scope retailers, such as Andrews Communications, Binter and York Optical.

Cheers, and good luck.

Always work on the secondary mirror first, then the primary. Otherwise you'll just be chasing your tail.

Yep, - definitely secondary first, then the primary :thumbsup:
