Hi Tony
True...in the sense that if I (attempt) to observe from within the very city center of Copenhagen, then the level of light polution is on par with the all of the greater London area. Since Copenhagen is a LOT smaller than London area-wise, it doesn´t take much effort got get at least one better on better on the Bortle Scale.
I am in the outskirts of Copenhagen, and luckily my balcony faces SSW - towards the straight between Denmark and Sweden, so for planets I am fine....as well as Deep Sky Astrophotogry (obviously with filters).
That said.....I have actually seen some deep-sky objects from the Round Tower in Copenhagen. This tower has an interesting history....altought it´s part of the Church of Trinitatis, it never served as a Church tower, but was specifically built by Christian IV as an Observatory for the University of Copenhagen and was inaugurated as such at 1642 (but got it´s first telescope on
Fun facts:
Jean Picard visited the observatory in 1671 - although is actual purpose was to establish the actuel precise georgaphical location of Tycho Braha´s old observatoy at the island of Hveen (located in the straight between Denmark and Sweden, which he visited together with Ole Rømer - who then became Picard´s assistant from 1672 until 1681
Ole Rømer was became the Director of the observatoy in 1685 - but his famous discovery of the speed of light was done in paris in 1676.
Although the it losts it´s status as observatoy of the University of Copenhagen in 1861, it continued as a observatoty nonetheless, and is still active today, but with 6" Mertz which were installed in 1929. It is claimed to be the oldest, still active, observatory in the world. (Paris established 1671 and Greenwich 1675)
Clear skies
