Thanks Andy.
I changed the image back to the original version. I guess there is no substitute for long enough exposure. Back to adding more data next clear no moon nights.
I've done this object before with a TEC180 and Proline 16803:

Not as much detail in the reflection nebs but good detail on the dust and some surrounding Ha areas. I may try a blend of these and see if that brings up the image.
Greg.
