This is my latest photo - 35Mpx mosaic of Eta Cygni region in constellation Cygnus. 3rd bigger photo I took since 2008. Its 4 frame mosaic which contains 20 hours of H-alpha data and 12 hours of color, all combined together to create this multicolor image. It would be impossible to create this image without h-alpha filter. There is so many stars that all emission regions are hidden behind them.
