its not the RA and Dec axis you unlock as such, there are knobs where the head meets the tripod legs and it allows you to adjust your RA (true south direction)(not the one up the top of the head allowing you to rotate the axis's. and then theres 2 screws front and back that allows for your dec adjustment (up and down).
Yes it is crude but the idea behind it all is this. think of the sky as a white piece of paper with all the stars mapped out. then i come along with a map of the sky on a clear film. if i was to lay it over and move it around untill everything lined up you would be happy, thats what your doing when you do the 1 star align (you don't actually do a proper alignment process its just to find out where the mount thinks the star should be. and well hence the reason why you move the mount to the part of the sky it should be in manually (practically aligning the two maps as stated before).
Don't use the hand paddle to get the star in the ep as this will void this method from working as it should. all movements should be by hand.
it is the way to gain a rough alignment without spending hours. I can be fully polar aligned ready to go within 20 min for photography sure i can spend longer but it doesn't matter that much as guiding takes over anyhow!
