Hey Wade,
Normal thermal expansion and contraction will send a standard 'Newt' out of collimation as well as carting it about. Its inevitable and nothing to worry about.
As Rob suggested, heavier springs make a difference, but you will probably still have to collimate at least every other night. Sometimes you need to re-collimate over the course of an evening - again, not to worry.
I highly recommend a laser collimator, they make the process much faster and don't cost a fortune (80 - 200 dollars).
I was petrified the first time I tried it. Being completely cak-handed, I was prepared to screw it up and spend an hour of two getting it right.
All of 3 minutes later I was ready to go!
These fast mirrors can sense fear. Make them your b****!!!
