Question T-mount spacing distance/rings: Megrez 90 + FFv3
G'day all,

I have a Megrez 90 and the William Optics field flattener v3 which I'm trying to combine to produce acceptable results (so far without success).

From reading and asking on the WO Yahoo! group I am under the impression I need to change the distance between my FFv3 and my Canon 350D's chip.

A suggestion was these:

Does anyone have suggestions on products available in Australia which will allow me to vary the distance between FFv3 and chip at millimeter accuracy?



I'm familiar with t-ring spacer tubes of 10mm, 25mm, 50mm lengths etc that come with Meade focal reducers, but not anything smaller than those.

Thanks,
Roger.
