hey congradulations on the new scope
collimation is a little daunting to get your head around for sure even with all the videos and pictures on hand to boot.

Even the first pic in this article dosn't show exactly what you can see
as its a 2d representation of a 3d event
Start with the inside your the focuser draw tube , while peering down it
slowly pull your head back so as to close in the view on the outside edge of your secondary mirror, forget about any mirror reflections , just these two circular outlines , you need adjust your secondary so they both appear almost concentric and merge together.
Primary tilt is likely to be off as well ,again without tools looking down that focuser draw tube you want to be able to see all of your primary in the secondary mirror .. a simple cheshire will do the trick here to align the black dot.. when adjusting the tilt I use only two knobs at a time ,if those two dont work I move on to another two.
theres many great collimation tools on the market and its not a major chore once you get the hang of the basics..
good luck and enjoy your scope
