Meteors, airplanes, and the like are common issues with long exposure astrophotography.

If you're looking at taking a single shot and calling it a day, then you'll have to edit them out or discard shorts that contain them. Alternatively, and actually ideally, you'd stack multiple exposures with software designed to eliminate the outliers through averaging your data. Stacking will also increase your S:N ratio, but do to it effectively it does require that you have some sort of a tracking mount or take a bunch of exposures and stack them, but be willing to crop around the variance between exposures.

When shooting narrowband, I usually shoot for 30 minute sub exposures. While momentary outliers really don't get picked up, airplanes do have a habit of ruining subs. If you have enough to stack however, some of the usable data can be extracted and the unwanted data omitted from your combined data.
