If you cannot find a local supplier, the Stage micrometer scale kit at a cost of £2.25 can be ordered by registered Cambridge centres on the website here. For this you will get high quality eyepiece graticules supplied as part of the kit, which is good value.
Alternatively, the supplier we recommend that will sell eyepiece graticules is Philip Harris (they will supply overseas customers): www.philipharris.co.uk.
