Star cluster M71 - telescope processed image. M71 is a loose globular cluster in Sagitta, 13,000 light-years away. Lacking a dense core, it resembles a rich, open group of stars.
Star cluster M71 - unprocessed image. M71 baffled experts: it's loose like a young open cluster but ancient like a globular one. It is actually a rare, metal-rich globular.
Starting to do some #cluster observations with the Odyssey Pro tonight here is #M71. #unistellar #odysseypro #space #astronomy #amateur
M71 The Angel Fish Cluster - telescope processed image with Moon and Sky Light Filter. M71, the Angel Fish Cluster, is a loose, metal-rich globular cluster in Sagitta (The Arrow) that was long mistaken for a dense open cluster due to its sparse appearance.
M71 The Angel Fish Cluster - unprocessed image with Moon and Sky Light Filter. M71, the Angel Fish Cluster, was misclassified for decades! It's an unusually loose globular cluster, often mistaken for a dense open cluster.
M103 - telescope processed image with Moon and Sky Light Filter. A relatively small and distant open cluster in Cassiopeia (NGC 581), it's one of Messier's last entries, featuring hot blue stars and a notable red giant.
M103 - unprocessed image with Moon and Sky Light Filter. M103 is one of the most distant open clusters in the Messier catalog and features a very bright non-member double star that appears to be part of it.
Decided to look at various #star #clusters last night. Here goes with the first two. First images are #M71 #TheAngelFishCluster, and the last two ais #M103. #seestar #S50 #space #astronomy #amateur
M71 Angelfish Cluster - telescope processed image. M71 is an unusually sparse globular cluster in the constellation Sagitta, about 13,000 light-years away. It was once mistaken for an open cluster.
M71 Angelfish Cluster - unprocessed image. Its identity was debated for decades; some astronomers once thought it was a loosely bound open cluster, not a true globular one.
Next on last nights observations is #M71 #AngelfishCluster. This is a 191 image sack put together by the s50. Beautiful Starfield in this image. #seestar #S50 #space #astronomy #amateur
Did an automated run of half an hour each on assorted high altitude Messier objects after a failed run at Palomar 4. #astrophotography #seestar #M102 #M92 #M57 #M13 #M27 #M71 #M15
