Wow, very interesting, this discussion.... To my taste the processing was overdone, yes, but I believe that Oleg Bouevitch's intentions are genuine. I think that he had close to perfect circumstances, something that doesn't happen too often to all of us. Postprocessing can be done in so many ways, depending on seeing and telescope, and we know that it can lead to different results, but not necessarily 'fake' results. It's also a matter of taste.
My suggestion is to stay kind and respect his choices and maybe ask him to elaborate more about his technique. It might be interesting after all. From a second Facebook post of Oleg (see https://www.facebook...757.-2207520000..) I understand that he agrees that "the sharpening could be turned down a bit". Anyway, he must have had (close to) perfect circumstances.
Regarding the image itself, something caught my attention; it's the two brighter spots under Olympus Mons. Could they be new storms?
I hope he'll join in to show his workflow....
