Where to get 232mm rings?

[Gruffalo]

I am trying to find some 232mm rings to fit an R200SS reflector - I have tried Bintel 8" rings, but they are too narrow and distort the tube (unless I remove the felt and use thinner - may try that). Maybe the SW 8" rings are close to 232mm - can someone check? (they SEEM like direct copies of Vixen rings anyway!)

Will slight tube distortion affect it anyway, seeing there is 15mm gap between primary and tube wall.

The SkyWatcher 8" rings are 235mm, according to astroshop.com.au.

Cheers
Steffen.

I got mine off myastroshop.com.au a while back - Steve Massey is the one to speak to
