UGC 695 (Cetus) Isolated dwarf galaxy (30 mly). Alias: PGC 4013, LEDA 4013 UGC 695 is a low-surface-brightness (LSB) galaxy which make is pretty faint. These galaxies are so faint that their brightness is less than the background brightness of Earth’s atmosphere, which makes them tricky to observe. This low brightness is the result of the relatively small number of stars within them Image affected by poor transparency & corner condensation/frost. Target to be rescheduled |
