| Image Details | Up is 180.5 degrees E of N. Total integration time was 42m. Exposures 30s@305g, UV/IR Cut Filter. Darks subtracted, no flats. Dithered and recentered in SharpCap. No guiding. |
| Description | Another surprisingly good capture given a waning moon just a couple of days past full. Luckily aiming directly away. These galaxies are astonishing. Two appear so well integrated that they have a single NGC number instead of two consecutive, or, as you see often an A/B. They both seemed to be irregular barred galaxies that, by this point, have merged galactic centers. Even Arp seems resigned to the fact in his remarks: "Bright internal knots." The dwarf IC 694 seems to be sucked in from the bottom of the image as well. |
