This image is a blend of narrow band data gathered with Ha, SII and OIII filters. Each of the original frames was a 2x4 mosaic with a total of 8675x8775 pixels. The view presented here is a crop of the full frame that has been reduced to half the original resolution. Still the largest image provided here is 3200x2400 pixels and it shows lots of detail.
