“Meridian” was a small telescope firm owned by Björn Hedvall. All Björn Hedvall’s refractor scopes were from Nihon Seiko, but branded “Meridian”. Björn Hedvall (now deceased) was also supervisor for a public observatory in the town of Gothenburg, Sweden. The lush forest, Slottsskogen (Castle Forest), has been the home to the observatory since 1929. It is the only public observatory in Sweden. You can check their website: http://slottsskogsobservatoriet.se/ for additional information. This link: http://slottsskogsobservatoriet.se/nyhetsarkiv.html#hotat has some good photos of the telescope in use.
The observatory currently possesses a 5 inch Polarex refractor and two 4 inch Polarex scopes on a single mount.
The 5 inch Polarex is still in use; however, the “double” 4 inch Polarex scopes shown in the photos below are now in storage.
Tore Engen from Oslo, Norway, visited the observatory in August 2016 and provided several photos of his visit, including this photo of the 5 inch Polarex that is still in use. As I indicated earlier, the double 4 inch Polarex telescopes on the single mount have been replaced.
