Beautiful Triffid Peter, I just looked up that camera and it's a good thing I was sitting down, serious kit.

Its a very special camera...unlike any I have used......It takes some getting used to especially if you are used to CCD and doing long subs. I found the longest sub on faint objects and narrowband only need to be 180s, 60s for Luminance on brighter objects.....so no guiding and less time waisted if you get a bad sub. S/N ratio at 180s is pretty much the same as 15mins on the equivalent CCD sensor (16803). So you get the benefit of frame volume decreasing the noise floor further. 

I have been grabbing lots of data hopefully will have a few more data sets completed soon.... the weather seems to have improved but I'm working around the moon.
