Image is mosaic of many images taken in narrow filters. My first pro photo and thought I would show it to some people who do much better with much less. Each field is 3 exposures of ~900sec combined to reduced noise and cosmic rays. Red:Ha Blue: 6100 continuum filter Green: 5007 Angstrom OIII. Composed of two different fields taken on two nights and combined with IRAF with color processing in IRIS. In JPEG form it is 3 pixel/arcsec.
It was a mossaic camera with two ccds so it was about two months to get everthing done. There were also light leaks on the first night which made things a mess. Stair steps and stuff.
Let me know what ya think.
