Sure. You can resolve M-13 (a globular cluster) from the city
with a 5", especially one that produces good star images. Don't
expect the kind of detail you see in a 10" though. Get a LPR filter
as well.

Assuming it's working properly and is set up properly, yes.

How exact?

Can't hurt. Better than exposing the corrector lens to the sky directly.
But dew will eventually form if the air is damp and cool.
