Yes it's definitely a challenge object when you drop down to the 15x range. It's a very nice view in my 30x77mm binoculars, and I can just split it in my 18x50 IS Canon's handheld, although it's borderline.
The separations are around 13" and 15" (I see an earlier post listing it at 14" and 16" - this may be choice of rounding or truncating the fractional part).
There's another thread here about splitting 100Hercules which is a 14" separation that I was just barely able to catch in my 11x56mm Garrett's (possibly 11.75x?) but which I could not split at 10x although two other posters claimed to catch it at 10x and even 8x.
But the secondaries here are quite a bit fainter too. I still think though it should be do-able with 15x under good viewing conditions. Perhaps some other viewers can take on the challenge and report their results! I find objects like this to be an ever-entertaining aspect of binocular observing.
