Got an old binocular eyepiece hanging about Leon? If so, drag a set of crosshairs across the field stop. I have used "streamers" of glue, like F2, or real hair, (before I had a teenage daughter). If all else fails you can sometimes find reticles in surplus type places.
Illumination can be from a small LED. Drill the correct sized hole in the eyepiece body side, at about the reticle area, and it should illuminate the crosshair.
Otherwise, keep an eye on Astromart.
