Collimating is easy with a collimating tool, like one of them laser collimators... people gets all stressed about how hard collimating is...but its real easy and you can easily do it with the right tools... also, you might wanna change the philip screws for the secondary collimation to a bobs knob.. they make things a lot easier.. i doont have them cos im cheap..
also, you can get a fan for your primary but you wont need to cool your scope to collimate.
just me 2 cents worth
