Outstanding! Taken from a dark site or from a light polluted area?

I imaged the Rosette, too, about 2 weeks ago, from Bortle 8/9 skies, using a similar sequence.

My image is not nearly as good as yours, but the interesting part about it is that I managed by pure luck to catch the asteroid (6) Hebe as it was passing through the left lower quadrant. You can derive the sequence I used: Ha, O3, S2 from the trail of the asteroid and even calculate when the meridian flip occurred based on the gap in the O3 sequence.

Hi guys, thanks for your comments!

El Corazon, it was taken on suburban orange zone with lots of street light pollution.
I use 12nm Optolong filters , they capture some light pollution, but with some work, it gets out of the picture.

Also, great shot and lucky on that asteroid :-D
I have to capture the SII and see how it goes.
