  • My EQ6 mount is good but there are some weak point in the construction. One of them is the Altitude polar align adjustment. When living at 60 degree latitude as I do it doesn't work very well. Here I starting a study of what others have done and what equipment there are to buy to solve this problem:

July 14, 2019 Travels / Sweden

  • One place I always have found beautiful in books is Norrköping and its river Motala Ström. We have travel by car through Norrköping many times but never stopped at the old town center. This day my girlfriend had to visit the archive of Norrköping in her research and I follow to walk in the old city of Norrköping and take some photos:

  • One old idea I have is to take old photos and then take new ones from the same place and compare. I have started with the island Riddarholmen in Stockholm. The old photography is from the 19th century. Much more complicated then I first thought, it will take long time, here is the beginning of the work:

25 april, 2019 Sweden Resor till sjöss

Min fars äventyr som sjöman under åren 1937 till 1945:

  • Vem har inte drömt om att göra en jorden runt resa någon gång i sitt liv. Min pappa Evert gjorde det redan innan han var 20 år fyllda. Han mönstrade på handelsfartyg och hamnade ända borta i Kina och andra länder i Asien. Det här skedde delvis under Andra Världskriget, det var många fartyg som gick under från minor och torpeder, även svenska fartyg. Tre av fartygen han var på förliste pga detta, dock något efter att han mönstrat av. Trevligt nog har jag en hel del bilder till pappas alla berättelser om de här 7 åren till sjöss. Denna spännande historia kan ni följa här:
