Quote:Very nice image. I'm interested in the processing details. ...Keith
Quote:I was surprised at how much your bicolor image matched the color of the tri-filter natural-color narrowband image of the Bubble that I posted the same day. I think they match because the SII in this object pretty much follows the distribution of the Ha. So when you blended Ha into your green channel you highlighted the same "fiery regions" as the SII did in my version. Very interesting.
Quote:Here is (calibrated via bf-astro eXcalibrator) an unprocessed crop of RGB from CCDstack that I was planning to put in (got lazy and didn't) to enhance the stars. Yours stars match up pretty close. Pretty cool since it is all narrow band.John D
