This is my first attempt at the center NGC 2244. After tossing bad sub I ended up with 110x120s Ha, 50x120s OIII and 40x120s SII at unity. I am still working on getting to grips with processing, for this image I used AstroPixelPro for pre-processing and PixInsight for combining and later work. I had to use star mask and “MorphologicalTransformation” to reduce star size, so I had to learned something new on this image also, just hope I didn’t do to much. Tried using a Blended Channels Combination with R/K – Ha, G - 0.4Ha+0.6OIII, B – OIII as color palette for the first time. Wish I could get some more color out but it seems all I get is a very overexposed image. I would really like some feedback on my progress so far.
