thanks for trying this for me ted, the first pic i posted was to show the blurry laser reflection with the black hole centre at top, we did actually get it centred ok, but was wondering if the blurry laser may have something to do with all three laser images no all coming together on the screen at the back
we will go around to peters place (stardrifter) again and brian norsdrum may attend also, so maybe we can nut it out
BTW ted does your whole secondary housing rotate within the corrector if you turn it?
regards
pat
