Hi Tom,
welcome to IIS. Anything Televue will be fine. I have the same barlow myself as well as an assortment of TV plossls. These are all great eps and will be noticably better than the cheapies that usually come with a scope.
As you'll see, TV offer a huge range of different quality eps, all the way up to the legendary ethos range - which of course we all aspire to.
Cheers
