Lovely picture! Pity that so many astronomers still do not understand that to investigate such a galaxy it is important to take the point spread function into account properly. I.e., read Sandin 2014A&A...567A..97S and Sandin 2015A&A...577A.106S!

If you know the response function of your instrument, you can deconvolve it from your measurement to obtain a much sharper signal. But deconvolution is a dangerous procedure, as small mistakes in the kernel can result in heavy artefacts.
