Deep Space 9, obviously. Though I personally don’t think that should count, because I’m going to count “stuff that was first on TV when I was a child.” So instead, I’ll promote these two, which first aired in the U.K. 1980-2 (I was 5-7 years old) and which I remember watching when they were first broadcast in England.
Star Fleet was the U.K. adaptation of X-Bomber, a Japanese puppet show and my first introduction to the tropes of sci-fi anime. It was awesome. The Brian May theme helped.
Huckleberry Finn and His Friends was a Canadian-German production and mostly filmed in and around Vancouver, where I now live, especially at the Burnaby Village Museum and on the Samson V paddlewheeler (which I can just about see from my window, it’s a museum now).
