It was a great pleasure to use Daniel's 14,5" f9 RC together with the new FLI PL16070. This modern camera is really fast (which makes focusing a breeze) and still quite noise-free. At first I was really worried about guiding at 3.3 meters focal lenght but after the first 10-minutes frame I immediately changed to 20-minutes frames.
The O3-signal was combined with the RGB-signal from the corresponding part of the image acquired with the refractor.
