Jupiter's father in St. Petersburg has a brass-bound telescope, an expensive antique with poor optics that would not be used by a serious amateur astronomer. These scenes must take place in the 1990s,, when St. Petersburg was still recovering from the Siege of Leningrad, the longest, most destructive, and most lethal siege in modern history. There were decades of severe economic depression with food rationing, infrastructure failures, and multiple families lived together in 'kommunalkas' ('communal apartments') that would at most house a single family in much of the rest of the world. Luxury items like modern telescopes would have been completely unobtainable. Even antique telescopes with poor optics would have been seen as decadent and would likely have been traded outright to benefit one's family or, as in the film, stolen by others. See more
