You don't define "low frequency", so it's kinda hard to tell what the
advice should be to you.

You do mention "moving spot", I would assume that means you're using an
analog scope and the signal you are viewing takes perhaps a second or
two of "sweep" time.

One option is to turn the brightness up to the max, and turn off all
other lighting. By doing this you MIGHT get a hint of the actual trace,
but I doubt it.

Best solution is to get a DSO (digital storage scope). Many options out
there, for low freq stuff like what you describe the cheapest PC scope
will probably work well.
