Could be, Ken,
But remember, these reticle eyepieces are not good visual eyepieces. If you want a decent eyepiece to do scale drawings to, you still need to work with good eyepieces. My second post is intended to show how you can make your own simple reticle EP to measure with, and if the OP is clever with their hands, it would not be difficult for them to knock up a grid reticle, all the while using better quality eyepieces than these ready made reticle ones
I happen to have sold one such eyepiece to you too!

We spend so much time chasing our tails for good eyepieces, so why should we forget this with reticle eyepieces?
