Very nice Paul. Great colours in the Helix itself.
Try binning your Ha 2x2. The O111 is just the spoke type centre and a bit out from there. S11 is very little at all, more just a fainter version of the Ha.
You did great getting that much from that amount of exposure. It is very faint. More a target for your 12 inch RC with a reducer and bin Ha 2x2.
Greg.
