By now, it's no secret that I'm trying to complete the Messier catalog by photographing all 110 objects listed there, and today I managed to put together the first piece of this photographic marathon I began over four years ago: grouping together all the globular clusters (my favorite objects, but this is no secret either) observed by Messier in the 18th century. My first Messier object, which I photographed in June 2021 with my first cooled astronomical camera Qhy8l, was indeed a globular cluster (M5), and from then on I began "collecting" them all, using what I could from home. At a certain point, I found myself blocked because many objects were not visibe from my homa due to buildings and trees, including the many summer globular clusters, which are very low above the horizon. In this case, remote astrophotography, which many oppose but which I find equally stimulating just like when I use my orange Konus, was very helpful. And so, with the photo of M70, I've completed the circle of Messier's globulars, which I've included side by side in the attached collage. In the last box at the bottom right, you'll find all the catalog numbers of the photographed objects. Follow all the links to the high-resolution photos, which also include all the details on the equipment used.
