2" collimation sight tube?
Hi,
is anyone aware of any 2" collimation sight tube available in Australia? Need one badly to help collimate my 12" newt. With the dollar where it is, the price from the US is more than I can spare at the moment.
Alternatively, if I could find some 2" aluminium tube I could make one, but can't find any available here :-(
cheers
Gary
