Doogal and
I'm glad you are enjoying your 12" dob.
If you face South and can see the southern cross just point your dob in the direction of that greyish band that goes from left to right all night across the sky (The Milky Way) and you will be enternained all night with lots of goodies, and while your at it have a look at Alpha Centeuri and some of the stars in the cross and you will see that they are doubles.
Go and buy yourself Astronomy 2007 from a book shop or one of the astro shops you will be amazed what you will find in your 12'Scope.
Keep on enjoying your new hobby
