As for the searching method, here is some details (How I have always done it, at least) :
Graphics settings : Low (be sure that everything is set to the very minimum, EXCEPT "Model Drawing Distance", set to max) / Gamma to max / Field of view to max
The above will effectively simplify planetary surfaces as much as possible, and remove any visual clutter (like AO, strong shadows, etc)
Planetary features :
- Terminator and/or dark side
- Near "important features" eg. stick "big" next to the following : craters, canyons, mountains
- Nearly always the presence of POI parker circles on your radar when you're close to it
