Here is the final 3 by 3 frame mosaic of the Veil Nebula, a supernova remnant from a star that blew up around 8000 years ago (source Wikipedia).
Each frame has an hour exposure at the moment, something I may add
to on the next clear night. The processing of this one was somewhat
tricky as the conditions were variable night to night. Some of the
frames had brighter backgrounds than others and although Microsoft's ICE
did a reasonable job of matching them there is only so much it could
do. I did come up with a novel way of using the multi-scale
decomposition tool and a layered combine with a synthetic residual
layer that worked very well. Matter of fact it worked so well that I
may be able to replace flats with it in my normal processing. Click on
