January 20, 2023 Astronomy, comets I found this comet in my archives from 2016, didn't do anything with in that time more than a test with relative guiding. Poor data and lot of dust blobs. Now I got to find the weak magnitude 18 comet: The comet PanSTARRS C/2014 W2:

January 17, 2023 Astronomy, comets One more comet that I sat on the waiting list three years ago. These weak comet are not much to see, but exiting to find them on the photos. As you maybe already know I live at a Bortle Class 9, place, as worse as it can be.: The comet Atlas C/2019 N2:

January 16, 2023 Astronomy: Tutorial One of my first tutorials I wrote was about how to do a relative guiding on comets. It guide on a star and the computer calculate the offset speed between the star and the comet and correct for that. I have looked through the text and updated links and added more photos. The software has developed a lot but still the principle is the same.: |

Then I saw that I had the constellation Great Bear outside the window. Why not take photos of the seven stars that built the Big Dipper which is a part of the Great Bear ? Afterwards I can analyze the images and see what's more there, sounds a bit exiting to me:

Mars 23, 2021 Astronomy prof Gösta Gahm 
I, prof Gösta and Peter at the Sweden Solar system presentation, Gunilla is the photographer. Something very sad has happen, in January 2021 I got the information that Gösta had passed away. We had known each other for more than 25 years, both I and Gunilla had him as a teacher in more than one courses we took in astronomy from 1995 to 2002 and we kept the contact since then. This meeting with the Jupiter model was the last time we saw him and at Christmas I got a greeting from him, since then nothing. Goodbye Gösta, we hope you have a great time up among the stars ! Gösta has one asteroid named after him: 10997 Gahm. Lars and Gunilla
