These 3
Astrobin Debut Objects are located in the constellation of Hydra at a declination of -27 degrees. All 3 galaxies are magnitude 13. These 3 are at different distances away from us and are therefore too far apart from each other to be interacting, which is confirmed by the lack of any visual interaction evidence.
As one would expect with PGC galaxies, nothing in the image was resolved by any of the platesolvers and I couldn’t find much information on them. I imaged them because I liked their structures, which I identified from scanning the DSS survey in Aladin.
PGC 49473, at upper left, is a magnitude 13 spiral galaxy located 160 million light years away. It is 90,000 light years in diameter. This galaxy is edge-on to our view, as seen by the beautiful dust lane which bisects the glowing core.
PGC 49420, the bottom galaxy of the pair at lower right, is a magnitude 13 face-on grand design spiral galaxy located 240 million light years away. It is 100,000 light years in diameter. Although a grand design spiral, the arms are not truly point symmetric.
PGC 49421, the top galaxy of the pair at lower right, is a magnitude 13 lenticular galaxy located 290 million light years away. It is the largest galaxy in the image, at a Milky Way sized 120,000 light years in diameter.
