The other problem is that not all reticle eyepieces are created equal...
I bought a TS-Optics 20mm Crosshair 70° ERFLE to try out, the crosshairs were lovely and clear just not in the centre of the eyepiece. Rotating the eyepiece in the focuser scribed a circle half the moon's diameter.....
I did remove the eyecup and nosepiece before the rest went into the bin.....
