If NGC 6118 is considered the most difficult of the H400 then they are all possible with a 6" scope.

Yes, many people have done the Herschel 400 with 6-inch scopes. It's not hard at all under dark skies.

I'm not sure I'd call NGC 6118 the hardest. It's undoubtedly the faintest, but when all is said and done, it's just a pretty typical, moderately small, moderately low-surface-brightness galaxy. A little tricky through my 7-inch scope from medium-dark skies (SQM 21.1), but extremely obvious in my 12.5-incher from the same location.

NGC 6540, a heavily obscured globular cluster, is the one of the Herschel 400 that gave me the most trouble. Not so much seeing it as being sure what I was seeing, or supposed to be seeing.

I found a copy of my original report to sci.astro.amateur after completing the Herschel 400 here.
