Illuminated reticles

Increasingly when I set my EQ8 and telescope up somewhere new I have started using the built in polar alignment routine, centering the alignment stars using the illuminated reticle from an old guidescope, combined with a 4x powermate. I reckon it gets me close enough without the problem of needing a computer screen near me during this part of the setup. It is also disturbing for other people. Performing alignment using an eyepiece is way easier, more intuitive and even enjoyable.

Accuracy would be even better though if I could find a very short focal length EP that was also had an illuminated reticle. As far as I can tell though all the ones that exist are of a medium focal length - 10mm or 12mm - and I suspect that is what mine is. I don't need it to have any optical quality I just want magnification. I want a 3 or 4mm. Does anyone make such a short illuminated eyepiece?
