When I was younger I watched a Astronomy show on PBS. It was on weekly from what I remember.
It started off with a image of Galaxy Spinning ( Cool Spacey Music to boot) and a host would appear (I believe he had a mustach.)
Sorry about not being able to give more details. I was very young.
Any help would be great.
I'm not 100% if this show was done in the 80's Maybe late 70's.
