So i finally got my sample of a portable Dome made, it needs a few modifications, Better more rounded shape and a Silver outer coating. But it Pop-ups in 5 seconds and it can be packed down in 10 seconds to a flat 70cm round carry bag. As it has 4 adjustable (velcro tabs) windows moving it around should be kept to a minimum but if you had to move it then it is only 4 pushed in pegs and it weighs less than 3kgs - just pick it up and turn it.
I know this spring steel frame is not a solid structure and if the wind gets up it has 4 rope points to secure it, anyway it is for a fast easy shelter and it works.
In the photo the table is 70x70x70cm High for reference the shelter is 2mtrsx2mtrsx2mtrs High. The scope is a 12" GSO on a EQ Mount. I have the door and window open to see the inner.
