I would not attempt collimation until I've had a look through the 'scope to see what the images were like on many different nights to account for different seeing. You don't want to inadvertently take it out of collimation. However you should be able to test on an out of focus star that is precisely centred in the field of view on the first clear night provided the seeing isn't terrible. As for the collimation procedure first read the manual that came with the telescope. Most SCTs hold collimation from the factory very well but it is still good to check but not fiddle yet.
