    OK, Orion Dob Tubes are made of Steel. :P

    How about a Dob made of an old cannon? A) the mount is pretty much there already and B) ... it would be... really heavy. Yeah. Good reasons!

    Dude, like, rifling so messes with your light path, y'know!

    You might be surprised about the size issue. I measured the dimensions of my mom's car's trunk against those of an Obsession 15", and the Obsession fit (it's not a particularly large trunk, either). I may even have been able to squeeze the 18 in, but it would be tight. Granted, though, those are both premium truss Dobs, not solid tubes.

    basically, I think it is possible to have too much mirror depending on how close you are to sea level.
    The where he lives question is more important simply because, if he's not in the US or Canada, Orion won't ship to him (read their shipping policy just to make sure). The "too much aperture for the light pollution level" is simply a myth. For pulling out fainter objects, bigger is always better.

    Plus, the bigger the aperture, the more magnification you can use and magnification darkens the background.

    Oh, I realize a truss style dob can break down such that a pretty dang large scope will fit in a lot of vehicles, but I like that my solid tube requires no assembly time in the field, other that plunking the tube onto the mount. It's a nice compromise for me.
