Vixen's 8x50 right-angle "Polaris" finderscope -- found on older Celestron Ultima SCTs and also available as an accessory -- included a polar alignment reticle and illuminator. I believe it's now extinct. There may have been a few other finderscopes which utilized polar-alignment reticles, as well, but I don't recall any.
Cheers & best wishes.
