Thanks Rich - I was genuinely surprised and happy to get some dust coming up in the lum. Bit of an eye opener that the rig can go a bit deeper on less mainstream objects. The "Sunflower" galaxy is another one I'll have to try in more detail next year.
You wouldn't believe it - this was an early image when I was learning to use CCD Commander and I found another single R, G and B image last night on my hard drive that had been named incorrectly. Not sure I can must the energy to reprocess it all for an extra 12mins in the RGB. I suspect I could conceal some more of the star colour bleeding if I chose my reference image for stacking more carefully too. Must be getting rusty.
very nice image,surely one for your Messier Catalogue
