Description

Here's the LRGB version. I also collected Ha data and am working on that now https://www.astrobin.com/jmuwit/. I find galaxies like this, that have such a 'globular' structure, a challenge for sharpening and deconvolution. Attempts to bring out the dust lanes over-sharpens the globular nebulosity and quickly gives it a very unnatural look. So, other than deconvolution with BX using the measured fwhm, I used a range-mask to sharpen just the area surrounding the core. fwiw.
