Under decent seeing conditions and with all scopes properly cooled and collimated, be rest assured if you see Antares B in a 6" mak, you will also see it under those same conditions in any 1/2 decent 8" or 10" newtonian. Under good conditions with my Suchting powered 10"/f5.3 SDM I can drive a truck between A and B.

I have seen Antares B on many occasions in a 4" Takahashi FS102 under good conditions. I have also seen conditions on many occasions where I couldnt pop it in a 25" newtonian due to stars bloating to the size of soccer balls under poor seeing conditions.

I've seen Antares B in my 8" F/6 newt without difficulty in average seeing. Personally I find it a harder target than Sirius B.
