Hi Mark
Talking of useless, you should have seen me trying to use my first scope!
Anyway, to align your finder, first take your scope outdoors. NEVER POINT IT AT THE SUN! (Sorry about the capitals but that is important) Best bet is to set it up in the shade.
Then select an identifiable object as far away as possible. I use a TV aerial or chimney pot. Then opo in your long eyepiece (25mm) and see if you can find object and focus on it with the eyepiece in.
Then look through the finder and see if the object is visible. You can then adjust the finder. They usually have two adjusting screws and one spring loaded one. Play with the adjusting screw until the object is centred and Voila!
Then when you take it under the stars, pick a bright star or Jupiter, find it in the finder, then it should be in the main scopes view, if it is off centre, recentre it then adjust the finder again. Once that is done you are set for the night.
I usually adjust each night to be sure.
