"Burning" the edges [of the final print] to the extent it mimics the "deep black" of space, is in fact faithful to the scene. PJ's "Burn" the edges of news images everyday. That is, they "darken" the edges to create relative contast to the focal point they wish to show. This is not deemed unethical, but rather legitmatley "expressive". The terminology comes from film emulsion days, when the overexposre of the positive image to (unfiltered) light, would darkens the photosensive elemnts of the (white) paper. The fact that this was shot originally in MF film, makes me feel better about this, for some reason. The original negative would have been "clear" in this area.
