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)


Here I have collected news I found interesting.

Technology, Astronomy, Cars, Travels etc.

Moon light on the sky

19 oktober, 2018 Sweden

  • Uppdatering:
    Nu har jag exempel på Tyresta vid Spirudden samt Hagsätra där jag bor.

  • Uppdatering:
    Kunde inte låta bli, nu har jag lagt till en enkel beräkning för att visa skillnaden i signal /brus förhållande.

  • Uppdatering:
    Vi har haft några mörka kvällar ett par dagar nu. Jag passade på att ta några foton av M45 (Plejaderna) för att se om det syns någon skillnad mellan de olika platserna som jag skrivit om. Skrolla ned till slutet av sidan så ser du testerna från Ingarö och Gålö, med lite tur kanske jag kan testa Tyresta naturreservat någon natt längre fram.

  • Bor du i södra Stockholm och har svårt att hitta mörka platser att fotografera stjärnhimlen ifrån? Här är några förslag från mig och mina vänner:

  • Modification of the Star Adventurer L-tail or L-bracket.

Normally I want to orient the cameras sensor's long side against the RA. The included L-bracket doesn't have space enough hold the camera in that direction. Another thing is that I don't want to brought with me a balance weight when I'm on travel with my astrophotography equipment. Here you can see and read about my attempts to solve that:

Modification of L-bracket

This will not be the last modification.

  • Astronomy Observatory site: Skinaka observatory at Crete.

We visited Crete this year in September, we tried to visit the Skinaka observatory but the weather was not with us. Anyway the road up the mountain was very beautiful and exiting. I have photos from the road that maybe could be useful if you plan to visit the observatory in the future. And the nature is nice to look at too:

As usual we was a bit unlucky with the weather.

  • 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.

We visited Tenerife already 2016 but had not written anything about this earlier, but now it's online:

  • Modification of the Star Adventurer wedge.

I have a problem with the wedge, it can't be locked safely, here I try to fix that.

Next clear sky will tell if it works better after this.

  • Preparing for an astrophotography night:

We are now preparing for the astrophotography night. We stay at the summerhouse 30 km Eastern of Stockholm city. Our first plan was to meet friends at the nearby parking lot, but no one seems to come. Astronomical darkness from 10 pm to 4 am and the Moon is down. No clouds, all looks perfect and it's still +10 degrees Celsius.

We bring with us the Star Adventurer mini mount, Canon 6D with Sigma 150 mm f/2.8 APO, Canon EOS M with Canon 50 mm f/1.8. Heating band for both lenses and two USB power batteries. Everything mounted on a stable tripod.

What object did we catch? An open cluster:

NGC 752

After a lot of trouble with the mount I got the NGC 752 Open Cluster, read more details here:

  • Tired of cloudy nights? I almost gave up my astronomy hobby, but then I took a look what data there are in the archives that can be used:

Recently I found at Youtube some very interesting historical maps, from Sweden where I live to the whole world. They are animated and very educational too look at. There are information about people, borders, war and more. You will learn a lot from these.

If you live in Sweden as I do, start with the Swedish map to test your memory from the history lessons in school.

    Look at the photos, what a beautiful place at altitude 1700 m. I hope that we can visit that place in the future.

  • At the same place the amateur astronomy club Stellar Society Association have their observatory. Here is a video over the construction of the observatory: watch?v= 5d2ORktuuZg
