In a period approximately from 1967 - 1971 I remember reading a space adventure comic book with an unusually shaped spaceship with a crew of, I think, scientists-explorers. I cannot remember the details such as title or characters, except that I don't remember them being superhero types. But I remember being enthralled with their adventures. However the space ship left an image I still remember. It was, head on, H shaped with the legs of the H tilting inward at the bottom. The cross bar of the H had a dome on it and was the central area of action on board. If I remember correctly as I write this the dome had a large telescope mounted in it. The space ship was fairly large. It didn't have obvious things typical of the time like rocket shapes or tubes for propulsion.
I searched for comic book images and for 1960s comic book space ships, I've searched for space ships shaped as an H (there must be some very good AI judging from the images that came back in a Google search), but none matching what I am looking for.
