happy to take advice here - is a 9mm by itself or a 15mm mit barlow going to soak up more photons for the faint DSO ? I was looking at 9P Temple the other night with the 9mm and I think I had better contrast and brightness than the 15+barlow? The seeing that night also seemed to support the 6mm - I just wasn't all that happy with the apparent FOV and critical eye position - though I don't have much to compare to, so I may be being overly critical.
