I finally got round to processing this seminal and famous nebula, which has fascinated people for years. Out of the data provided I used 12 Has at 15 minutes long each, 14 OIIIs at 15 minutes long each and also 6 blues, 13 greens, 6 reds, 18 Has and 23 OIIIs, all at 10 minutes long each. Thus the integration time was 17.5 hours.
Enjoy your Sunday and thanks everyone.
