For big ships, as an emergency backup, that does seem reasonable. Note though that the weight may not be 'negligable' for medium-sized ships unless you have amazing materials tech - the ISS cupola manages to weigh almost two metric tonnes despite being essentially a bay window that clips onto an existing module - and that's just to cope with micrometeorites and radiation in low orbit, not the rigours of interstellar travel or resisting any sort of weapons fire. Even if you had one, you wouldn't use it for routine docking operations (incidentally the original Galactica featured exactly this kind of bubble for making nav sightings, but it was disused and treated as a curiosity by the main characters).Especially since, for ships as absurdly advanced as Star Wars ships, the mass penalty of a telescope, sextant, some star charts, and a small pressurized superstructure outside the armor belt is negligible.
Not necessarily a valid analogy. That's consumer grade tech that was relatively new at the time. Not milspec and certainly not space qualified. I think a more valid comparison would be fly-by-wire systems in aircraft: it's tech that potentially could fail, and certainly when it was first introduced people questioned the safety and insisted on redundant mechanical backups. But the reliability eventually got so good that the mechanical backups were dropped on high-performance aircraft to save weight, cost and maintenance complexity. Actually the Ace Combat series has a nice fictional treatment of this exact issue; the more futuristic and advanced fighter designs abandon canopies and have a redundant camera/3D display system, then eventually direct neural interfaces. The backstory details similar concerns about reliability (a lot of pilots don't trust it) that delays deployment, but eventually it just works so well that no-one bothers with canopies any more.Oh that's right, advanced technology never breaks. That's why my cell phone is rock-steady reliable, while my 50s vintage Western Electric rotary phone drops calls and sometimes just mysteriously refuses to work...oh wait.
