The tripod and mount are more robust, so I have a place for that already

As for Steve's commect on it being a new toy/hobby and finding a space...
I have a lot of hobbies, space is running out

I've had a look in our motorhome too and think I've found a place for the 'scope (OTA?), Now depending on how small the tripod/mount goes down, I might have a home for that too.
Having talked with my wife (it does happen occasionally) she seems to want us to get "The big one". I'm happy with this. I just have to work out a way of paying for it

Thanks again for all your help
Darren
