Frankly some of these guys disgust me. Pathethic in the highest order.
'An inch of ball'.
Well you have to understand that it depends on one's perspective:
The Fleet Office furnishes New TC's with 'Teste Calibrators'. These are used 20-30cm away.
There are staged upgrades: STC: Sizeable Teste Calibrators, for closer examination 10-15cm, and:
BTC: Big Teste Calibrator. This is for intimate macro work. Less than 3cm focal field. Amazing detail.
