This weekend the new Ha-filter arrieved. This 12nm EOS clip-inn filter had to be put up for the test. The week before I allready had the chance to image NGC281; The Pacman nebula. So I added 12 frames of Ha (360 seconds at ISO1600). After scouting the internet on Ha processing I came up with this result. Left without Ha signal; right with Ha signal.
