I reprocessed my image data of NGC2264, which includes NGC2261. I was never happy with the earlier image. The colors were muted and the image had an overall hazy appearance. I also had many noisy pixels that mad it through the processing. I processed the original image data again, using a better workflow and I am much happier with the result. Although, now I seem some other imaging artifacts, so don't look at it too closely
