Owing to the moon pointing almost straight down the tube, I've taken M42 in Narrowband (Ha,O3,S2)Filters. Could only expose for 3 minutes on each sub because of the light scatter. I made a special effort to focus tonight with the S2 and it seems to have cut the bi-spike out and the "ghost" appears to have gone as well. So it all must have been "finger trouble" on my part.

Damian, I'll send a full image by Bigfile.
