I struggled with this a bit, and the lack in my technique and ability has not helped at all. There was not a great deal of OIII, as far as I could determine and it seemed a little noisy generally, but I have done my best. Really good data and it was great to be able to try this.
Pier 7 is a William Optics FLT132 F5.6 APO, with a QSI 660-WSG Mono CCD camera, all on a Paramount MX mount. This was a Ha and OIII image, with 12 Has and 10 OIIIs used, all at 10 minutes long each - an integration time of 3 hours and 40 minutes.
Have a good day everyone.
