"Variations on a topic" could be the title of my recent photo collection, but that would not be entirely true. Though similar objects, but they are far from the same. Let's stay tuned to the Messier globular clusters. I decided on the twin thoughts this spring to scrape a couple of spheres. On one hand, my collection was very incomplete on the Messier objects and within the sets. The other main reason I received my telescope in the spring was an upgrade, an ASA 0.73 redundant, corrector in person. Thus, the focal length is 730mm F / 3.6. But the benefits are always a problem, so I had to do a lot of tests right now to get the reduction done exactly. Spherical sets are especially suitable for these tests, so some of the photos (M13, M3) are made by the M5 with the original 1000 focus and SW F4 corrector.
Spheres: The very old creatures of the Universe, the exact development of their universe to exactly this day are unknown to scientists. Certainly, a group of stars arranged in gravity-bound spherical symmetry. The number of their members ranges from 10,000 to over tens of millions. Amongst their stars are RR Lyre and Cepheid variables that help to determine the exact distance. Spheres are found in the so-called galactic halon around the galaxy. In the fish around the Milky Way we have ca. There are 160 such objects.
