At 116" long and 10" in diameter and weighing at least 501b you will need one mighty mount.

The same seller also has a tube, focuser and 9" rings, presumably for this lens on the bay also. Made out of air ducting, by the sound/look of it. Might be lighter than we think.

what about the obs in the back garden:eek:...........Kev

[George]

Wonder why he didn't just sell it as a complete OTA?

[Doc]

The tube is only 8 ft long. Surely a 9" F12 needs a longer tube.

Looking at the D&G website an 8" F12 scope needs to be 7 ft 8" and a 10" F12 needs to be 10 ft 4" so a 9" F12 should be 9ft.

[Rusty Strings]

Maybe you could use a 2 foot focuser tube!

Mearly minor details

I'd build something out of scaffold and have a bastardised dob-fractor.
