      Hello Friends,
      I moved to Aarhus from USA just a few months ago. Just put my equipment back together and shooting stars from Denmark. Amazing seeing condition here, way better than where I was (Philadelphia).
      I apologize for the English but I hope soon to start to attend classes to learn Danish.

      Although this image doesn’t seem anything special but its beauty is hidden in the details of the core of the galaxy. I did my best to preserve those details thanks to the resolving power of my refractor (Esprit150) and the seeing condition in my new rural location (in Denmark).
      I invite you then to zoom in, have a nice trip into the core of the galaxy as well as the surrounding faint galaxies nearby.

        Welcome to the forum and Denmark

        Great photo – there is a long road ahead before I can take and create pictures like that.

          Very intense colours.
          I miss to see a more detailed background.

            Thank you Claus.
            I am sure you will be able soon to take even better pictures. I am here should you need any help or suggestions. I will be more than happy to share my experience.

              I agree Torben, I love too the colors and the angle of this galaxy. The only problem is that it is quite a faint object requiring many hours of integration (or a very dark sky) to be able to pull the details of its structure.

                Astrophoto of deep space objects is not on my radar the coming year or more.

                About a year ago in late April 2021 I got a 70mm refractor as a birthday gift which re-ignited my interest in astronomy but the actual lift off was in January 2022 when I bought a notebook to be used as my astronomy log. Of the 300 pages I have used about 160 of them for sketches, describing and analyzing observations, history of astronomy, ideas and more.

                My focus is not to focus on anything specific but found out what you can explore with an entry level and beginner telescope in the 1,500 DKK (200 EUR) price range in the celestrial sky without investing much more than what is in the initial purchase: 70mm refractor, two ordinary eyepieces (20mm and 4mm in my case), barlow lens (3x in my case), LED finderscope and azimuth mount.

                I am living in a Bortle 6 area where 99% of the observations has been done yet in my backyard garden called Agertorium 😉

                I have observed double stars, open and globular clusters, asteroids, a dwarf planet and all the other planets except Neptune, the four great moons of Jupiter, some asterisms, Orion Nebula and the Andromeda Galaxy with its two satellite galaxies M32 and M110.

                I still need to observe variable stars, more deep space objects like galaxies, planetary and other nebulas, the Saturn moon Titan, the Sun and the Moon and maybe a comet or two.

                The goal is to create a Danish website, Youtube channel and/or a book for all the beginners who consider or have acquired such telescope so they can see what they can get out of it.

                I have attended two sidewalk astronomy events in Roskilde and Køge at Zealand where the two other telescopes was above the 1,000 EUR range. If we want others to be part of the amateur astronomy community it is important to show them entry level equiptment that is in most peoples price range to get their toes wet – and how to get more out of it than just see a close up of the Moon. And the history and/or additional information of the observed objects.

                Back to astrophotography – I have taken some pictures with my smartphone on a mount. I got a smarphone adapter for my birthday this year but haven’t tried it yet because of problems with the balance which I am working on. The main goal for using the smartphone adapter is to take photos of what actually can be seen with your own eyes and experience with the acquired equiptment.

                You can see my first smartphone photo of stars taken earlier this year which surprised me a lot.

                The most enjoyable greetings
                Claus

                  Claus,
                  I can sense your passion on those words. You need to acquire this book (if I may suggest). You will love it as it fits exactly what you are doing. Deep-Sky Wonders by Sue French. Link beow.

                  Next time you go to an astronomical event please drop me a message so perhaps I will join it too and meet you in person. We could join effort for your youtube/website project 🙂

                  Sincerely,
                  Sebastiano

                    Thanks for the advise. I will look into it later.

                    Right now I have lent all the three volumes of Burnham’s Celestrial Handbook at the library – I can see why it is called the “Bible” for amateur astronomers even though it was published back in 1978.

                    I use Norton’s Star Atlas – seventeenth edition to see maps of the sky. I bought it at Greenwich back in 1987 when our high school class was in London.

                    The biggest issue I have with both is that they use epoch B1950.0.
