Notes: This is a cute little dart-shaped group, made more interesting by the empty space around it. I struggled to rank the four stars in order from bright to faint. Sources disagree on their magnitudes: Burnham’s – 10.5, 10.5, 11.0 and 12.0. Megastar – 10.3, 11.1, 12.4 and 12.6 Skiff – 10, 11 and two fainter stars. Using the Megastar numbers my ranking was 11.1, 10.3, 12.4 and 12.6. |
