This nebula Simeis is really difficult.
I messed around a bit 'with the focal but this is the end result of fourteen hours integration that I did not want to trash.
9.5 Integration with Sbig 8300m and H-alpha filter Baader, fire a 180mm F3.4 lens Leitz Apo TELYT from the city center from where I live, other 4.5 hours with a Canon 5D MarkII Centralds to fire Apo refractor APM 105 f6.2 to f4 reduced from the mountain to the colors.
As I said a little messed 'with focal lengths because they had started as two different projects h and then for various reasons have not gone well, so as not to throw everything I have tried this not entirely happy marriage between different focal.
