At 21 solar masses it would have been discovered because of gravitic lensing from 100 light years away..
If they knew where to look, if it is at the edge of inhabited space, their might not be a nearby telescope that looks in that direction, and gravitational lensing requires a light source behind it that can be lensed
Space based x-ray emission detectors would spot them WAY out from inhabited space.
