Thanks fellas for all this advice.
I'm just wondering whether or not I buy a solid tube or collapsible, will I still need to collimate every time before I use it. Do solid tubes still require collimation before use? In that case, if I know I'm gonna be stuck with collimation no matter what, then I might as well get a collapsible version.
I've read that cheshire collimators are much more accurate, but it's hard to adjust the primary mirror and look in the eyepiece at the same time and so you need another person to help out by looking in the eyepiece. Can collimation with a cheshire be done with 1 person only, despite this issue?
