Hear , hear Matt , don't listen to that rubbish Ben , 70mm is plenty .
I have a 60mm scope and it is by far my most used , so small and light it is up and being used in the time it takes to walk out side , and it shows the moon as only a refractor can
.
Get out and use what you have , and yes they are a great starter set , and latter on sell them on to another newby and get another scope that suit's what you like viewing , ( me , I am a Luna , planetary kind of guy
hence my refractors and C9.25 CAT ) ).
