Hi Peter,

There is a scale called a stage micrometer which can be used to
calibrate an eyepiece reticle or there are special eyepieces called
filar eyepieces that have a reticle plus a micrometer driven reference
line. Both these items come up for sale from time to time in eBay.
Both items are listed now.. The stage micrometer is used to calibrate
an eyepiece objective combination.

Please contact me off line at
nghy_1@REMOVEyahoo.com for additional information.
