Craig, All,
Observing last night form southern Victoria with my scope and a friends 18" Obsession. We had a very nice night until cloud rolled in around 2am.
With many DSO seen you maybe interested I observed the Horse head in my 12" with a 17mm eyepiece and HB filter. We could see it easy in the 18" and I was very happy to see it in my 12". You did have to look hard and the little trick of just moving the field a bit. But once you eyes became adjusted to seeing something so dim you could see it fine.
So Craig you will be able to see it with your scope, but a dark sky and a HB filter will help a lot.
Happy hunting.
