Collimating a Newtonian

hey everyone. I am going to try to collimate my Orbitor 3500 for the first
time. I'm not exactly an engineering genius, but I am not completly lamen
either. I was wondering if anyone could provide me with detailed
instructions (or a web-link) that are simple and easy to follow. I would
rather not screw this up.

i should also note, that I have no special tools, and will be doing this
job with the bare basics.

thanks

My suggestions as well. Start with Larry's no tools page and see how it goes.

If you have problems, feel free to ask questions here or in private...

Nah .. the worst thing is that you can drop the secondary onto the
primary: It does happen easily with some designs and lack of care.

Uh, you mean NO ONE has ever totally unscrewed the collimation screws and had
the innards fall out???

Be careful about dropping the wrench too. It's not good to have a
wrench land on your mirror.
