Thanks white Rabit,
I have to pay off my car first

I wish my wife could understand getting a loan our for such a thing, however we are maxed out as it is.
Looks like a really great travel scope but a little big for my purposes...& I know I said BIG
The difference in weight from an 8" to 10" alone would be significant let alone a 15". But WOW that would be an awesome scope to own.
Here is an example of something I have found that fits pretty close to doable in a back pack.

I've ended up in the ATM section & the guys there seem to really know there stuff. I think I will be in no rush on this one, but instead focus on learning the finer points to building such a thing. That way I may just give it a go myself in due time & come up with my own backpack design, without too many comprimises.
Thanks again
