WOW! So much detail Bert. Its hard to describe. I've not seen the SMC in such glory. With exception to the brighter knots and twists of nebulosity, most of the fainter details are obscured by stars in the traditional true colour RGB images. You've done a great job on the data acquisition and I like your rendition too. The faint nebulosity extensions are really showing through. Well done.
I had a little play with the data set you have graciously provided. I seriously could have spent considerably more time to extract more detail. I think detail would come from contrast work as opposed to sharpening. Its interesting to work with as the dynamic range is huge so tools like DDP have an advantage. There is no doubt more to extract. Would be even more fascinating working with OIII data I suspect.
The second image is perhaps my most favourite part of the image but there are so many other cool things going on. A very busy image. Larger version (2.6mb) available
here for a limited time.
Thanks for sharing. Really looking forward to your end result if you managed to nail the other emission lines.
