Cool !!
And ..
.., your journey starts here.
Ok, so checkout Orions Sword. He's upside down to us so it's above the 'belt' of three stars. Your 70 mm might let you see something else you can't see with the naked eye.
And get Stellarium if you haven't already got it so you can figure out what you have just seen and what you want to see next. (Free btw).
Hang round, ask questions, read the good stuff on here and you will get aperture fever like the rest of us. There is no cure.
Find an Astro club and go along to one of their public open nights to see what else is around. They should be pleased to see you.
