Simple question. Can someone with one of these 10” lx200 classic or 10” lx90 pre ACF scopes measure the diameter of the central obstruction? The F10 model.0

What is it in mm or inches? I have heard the acf are bigger so I can’t use the measurement on the one I’ve got.

Thank you in advance!

I don't know that the F/10 ACF are bigger, but the F/8 definitely are larger.  For the 10" pre-ACF you'd also have one size for the F/10 and one size for the F/6.3

Very interesting that the lx90 GPS pre ACF had such a small central obstruction even smaller than the lx200 classic.

I don't get embarrassed very often but I am now. I just went out and remeasured the central obstruction on my 10" LX90GPS and it is just a bit over 3 1/2". How I came up with my previous post of 2 3/8" I'm not sure. Beer maybe  Anyways, I stand corrected.
