I spend this website many hours each week to share my knowledge and experience from the areas of Astronomy, Cars and Travels. Most pages are written in English that is not my own native language, so do not judge me too hard if you find grammatical errors and more.

Welcome to my home!


(these pages could be a mix of Swedish and English)

Totally new for me, maybe I will just use Twitter to advertise news on Astrofriend's website. Lets see how it develops. Old man learning new things.

  • Vem har inte drömt om att göra en jorden runt resa någon gång i sitt liv. Min pappa Evert gjorde det redan innan 20 år fyllda. Han mönstrade på handelsfartyg och hamnade ända borta i Kina och andra länder där borta i Asien. Det här skedde delvis under Andra Världskriget, det var många fartyg som gick under från minor och torpeder, inklusive 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 från detta och min pappas alla berättelser om de här 7 åren til sjöss. Jag har nu inledning klar till denna spännande historia som ni kan följa här:

    travel/world/evert-at-sea-1937-1945/ 01-evert-at-sea-start-sv.html
    (My father's adventures at sea, 1937 - 1945)

    Idag är det skrivet på svenska, men planen är att även ha den översatt till engelska.

  • When I have done investigating about my father's boat Monalisa I have come in contact with Helmut. He has bought a C. G. Pettersson boat with the name Sindbad in Sweden and then take it down to his home country Switzerland. He has done a fantastic restoration and rebuilt of the boat, here I help him to make a page with information about his fantastic project:

    (Helmut's C. G. Pettersson cruiser Sindbad, built 1914)

    Today I came in contact with Willy and Rasmus, two of the earlier owners and they could give us more information.

Helmut is eager to know everything about the history of this boat, if you know anything, let us know!

  • I have found new information in my investigations about my father's Petterssonboat. Maybe it's not a C. G. Pettersson design but a Victor Israelsson:

  • Tutorial: Remote control of Canon camera from a smart phone.

How many times have you tried to see the camera display when the camera pointing upwards to the stars? In my attempts to make my transportable astronomy equipment more user friendly I'm doing this. Make my Canon camera remote controlled from a smart phone:

Tutorial: How to make a Canon camera remote controlled

It's not difficult to use this remote function and you can use this to much more than just astrophotography.

Many years ago I read about CMOS sensors that in future could have non destructable read out. With that technique you can read out one pixel many times and with reduced readout noise. Alternative read out one low gain and one high gain and then combine these two readouts as a high dynamic data read out.

One problem, expensive! I hope that normally DSLR cameras use this technique in future.

You find above links later on the link page:

It could be as bright as magnitude +7, you need at least a binocular to see it.
