Rosette centre in Ha

My field of view is a bit small for this one. So this may be the first panel of a mosaic. Seeing was mostly bad so I was pleasantly surprised that some detail emerged of the dusty bits (which is what I was after).

Ha only - about 6 hours worth from suburban Adelaide on a ridiculously warm night or two. Captured with a GSO RC8 (reduced to f6) and ZWO 1600MM-C on a Mach1. The halos on the bright stars are courtesy of the ZWO Ha filter

Full res available on Astrobin here -and if you're interested there's an appalling attempt at colourising it with some RGB data as the next image in my library. I guess I need some luminance data to get a better balance? (I used the Ha as luminance).
