Think of task of monitoring the volume of sphere 80 AU or more in diameter. Now in that volume you have tens of thousands of natural objects giving off or reflecting EM emissions of various intensities. Then add all the human made sources of EM emissions of various intensities that are not trying to hide from you. Now try finding someone who is deliberately doing things to avoid standing out in all of that noise.
Atomic Rockets says everything needed.

There are things to hide in or behind. There are ways to be more stealthy in one direction than in others. However, any fictional account of actual stealth in space is going to be liberally salted with handwavium and bullshittium.
Weber has gravity tech and hyperspace to use for the, err, exotic elements required to create stealth in space. However, even those things don't make a lot of sense, because they can't. DW has never indicated that he's intentionally abandoning all reasonable physics. He's just indicated that we can't understand what's happening.
But the people in the Honorverse who DO understand these things should be able to detect wherever it is that the waste energies are being pushed.
If you are pushing energy into the first layer of Hyperspace, sensors in Hyperspace should be able to detect it.
Holographic systems simply cannot and will not work, because they can be trivially defeated by parallax detection, unless you create some sort of bullshittium out of particles that are smaller than particles, allowing infinite fidelity at infinite angles. And even then, it's questionable.
If you DO detect something in space, and you can move faster than light through hyperspace, you just need to get ahead of the event's light signature, which is traveling at the speed of light, and look at it again.
You can literally watch the same exact event occur several times in progressively less resolution as the event wave of light expands.
Keeping track of everything that *should* be making 'noise' in space is something we already do. That's how Radio Telescopes can get worthwhile data. They have to filter out all the known signals to get the interesting signals.
