I wanted to explore the deep sky too far south for central California sites. So I decided to build an airline-transportable telescope of respectable size, and do some voyaging. Lots of aperture and good light baffling were important, but obstruction size and tube currents were less so. I planned to transport the telescope on scheduled airline flights. I could put a larger telescope in checked baggage, than in carry-on luggage, even with enough padding to protect it from baggage handlers.
Some airlines are reluctant to check stuff packed in cardboard boxes, for example.
A web article suggested a problem with things with no handles for carrying, or too oddly shaped to stack well, or too flimsy. I ended up buying one. Most transportable telescopes are stored in pieces at home, driven to an observing site, and assembled there for use. As baggage, my telescope would be in more pieces, and smaller ones, than the average instrument in the garage. The plan was to unpack it in a motel room, assemble it there at least partly, then drive it to the site.
