The signal was accumulated during astronomical twilight (Sun 11 degrees below the horizon) at 55 degrees latitude from July 7th to 10th. For capturing Ha and OIII, I used HighGain mode; for G, I used Extended FullWell. The integration was done in the HaGO palette—essentially a "near-full-color" RGB.
