Just as a matter of interest, can you tell me why you devoted 100 min to Ha and only 60 min to OIII, when Tarantula emits overwhelmingly in OIII? It's a very blue nebula!

Hi Rob,
The nebula does emit in OIII, but it is still overwhelmingly Ha. There's usually a rant by Peter Ward about this time of year when the unmodded DSLR pics of the nebula appear, and are all sorts of odd coulours. Anyway, for my images the Ha response is large, compared to the other two and as I have a 4.5nm bandpass Ha filter (which should enhance the contrast over the 13nm one I also use) the Ha became the luminance part of the image, hence it gets much more time.
Cheers
Stuart
