230x - that to me sounds sufficient , but the object's small size and low contrast, as the glare from the star, makes it hard if one is not familiar with the object. I wouldn't worry too much about seeing, the smallest detail here is much larger than what the seeing will wash out, so I'd still go 300x +, preferably 400-500x. Nebulous objects such as this are far more magnification tolerant than objects with small details like the planets and small complex planetaries. It'll blow up the object and increase contrast between the neb and the dark globule so you'll have a much better chance of spotting it.
I use 3.5mm and 5mm LVW with 2x and 2.5x barlows in my 12".
