I purchased these along with a few other bits n pieces-
As ever first class services from FLO. The adjustment rings are individually wrapped and clearly labelled. Well made and easy to add to your M42 / T2 image train. I used the 0.5mm to make the required 55mm backfocus for my ZWO camera . Recommended.
Fixed my problem with filter draw access on DSLR

When fitting a ZWO filter draw to my DLSR the M42 thread locked in a position where the filter access was blocked by the top of the camera body. By placing one of these thin spacers on to the thread the fixing locked at a angle where the draw was accessable .....perfect easy fix!
