I'd be suspicious of external light sources in your observing environment reflecting off your own eye as well. I'd also make sure that your collimation is as good as you can get it, but I don't ever remember seeing ghosting even when my collimaion skills were less than perfect.
If tonight is clear I might go test it out again (collimation has improved) and report back see if get same effect. I've also purchased a AstroZap shroud which I've yet to test so i'll give that a go, hopefully it will elliminate it totally Cheers.
