Nice Boss , follow the tutorial Shark Bait pointed you to and you will be fine , its a good one .
Practice indoors with setting up and playing with the balance , with eyepiece in and once it as close as you can get it mark the OTA with a bit of white tape where the top of the top ring is along the OTA so you have a datum point to use every time .
Enjoy Daniel , great scope and any chance of a photo or 2 ?
