Oh that is just a satellite in one of the subexposures coming through.
Or perhaps a meteorite. They happen. Usually median combine filters those out but sometimes a bright one may still make it through.

That is just a bad filter reflection going on between the corrector lens and the filter. To some degree the luck of the draw, perhaps the Astronomik filters would have shown less reflections as I used to mainly use them with this camera and filter wheel. This image used the Baader filter set.
With the TEC scope I don't have to use the field flattener with the same chip 8300 and still get round stars to the corner so those sorts of bad reflections will be a thing of the past. This was one of the first images using the Baader filters with this camera as I normally had these filters setup with the Apogee U16M's filter wheel. But these Baader filters have great red response.

Thanks. It was a good setup. But too much the same focal length as my TEC180mm scope.
