150mm tube

Postby m101 » Mon Jan 28, 2008 8:16 pm

I happen to have an old 6" f/15 achromatic lense hanging about so does anyone know where i could get some tubing to make the scope out of? Anthing between 150mm and 160mm I can work with though it does need to be a decent length, the focal length of the lens is 2.25m so around that.

Any ideas?
Thanks in advance,
Alex

Find your local branch of Wright Rain, go to the yard, and slip the foreman a tenner for an appropriately sized offcut of aluminium irrigation pipe (take a hacksaw). The stuff comes in 9m lenghts, so there are often offcuts to be had.
