I'm a noob and have a problem. I've thought about getting a 6" Dob, but I live in a complex of townhouses and neighbours all leave lights on which shine into my garden so I'll need a scope that's easy to move, but I don't have a car only a motorbike and would need to carry it in a backpack or similar, 6 inchers I've seen seem too long and the smallest collapsible I can find is 8" and seem to weigh in at around 35-40+ kegs. I can't really afford or want a decent SCT.

Does anyone know if there are 6" collapsibles (it seems there used to be a lightbridge but they don't make them anymore) or a lightweight 8" inch collapsibles?
