If I'm not wrong some of the satellites of the first batch were deorbited already, so they don't operate a total of 180

"Less visible" is not good enough. The satellites will not be interfering with stargazing or with visual astronomy but they could ruin the astrophotography. Even the dimmest satellite spoils the exposure if in the frame. The question is not how visible they are but how many of them are out there. If astronomers can't find 1 or 2 min periods without a satellite crossing the field of the telescope then the astrophotography is no more. Having 12,000 evenly distributed satellites means that there will be at least one on every 1.85 degrees what is about the half of the Andromeda galaxy or also 4 moon diameters. What to say about having 42,000 of them. I am not SpaceX and mission to Mars die hard supporter anymore. At least not on that cost.
