Yes- the mass of the sun/planet/satellite/whatever being orbitted. Not the object that is orbiting. The orbiting particles mass is irrelevant. You said it yourself, F=ma gives you the equation a=GM/r^2 where M is the mass of the other astronomical body. Not the one you are currently trying to find the acceleration due to gravity of.
