Dave, thanks for that advice re circle on the primary mirror

. I did see the circle on mirrors at Bintel when I was there a couple of weeks ago. I'll definately keep this in mind as a consideration when choosing. I'm usually relatively handy doing things myself, but I think I'd rather have this done than messing around with it myself. I had in mind a laser collimator as a 'must have' to be included in the initial purchase, but didn't know the circle was needed to assist, so thanks heaps for this advice! I have no idea how to use a laser collimator but I'm guessing it should come with instructions, or be obvious when I get it. I'm sure there are posts on IIS re this too. Cheers mate.
Norm, I'm sure there have been a few cracks re 'Bob and his knob', so while tempting, think I'll leave it alone! One question though, does Bob only have one knob? I haven't looked into this too much yet, as you said they assist with ease of collimation, but is collimation still possible with the screws/knobs already there? So is Bob a single knob job, or does Bob come with multiple knobs? Tri-Knob Bob? Either way, another accessory to consider including in the initial deal!
Thanks for the welcome Alex. I've always seen a fridge as an essential too, but that has nothing to do with storing food!!!! Cheers
