Can anyone help? I bought a used meade 12.5" dobs and Im trying to install the primary mirror on the rear of the optical tube asembley. The manual says I need to line up the red marker on the rear of the mirror with the allignment marker on the rear of the optical tube. Unfortunately the allignment marker is missing on the tube and Im not sure what postion the mirror sits. Does anyone know with which bolt hole the allignment marker should line up with? Any help is appreciated. Please email me at [email protected]

If this is anything at all like the 8" version, I'm not sure what difference it makes. There are several 8" at the local college, and some have those red marks and some don't. I have done repairs on a couple of those scopes that required new thread inserts on the base, and that made no difference at all in scope operation. The only thing is that you might have to realign the mirror, which you would probably want to do anyway.
