| Image Details | Up is 95.9 degrees E of N. Total integration time was 60m. Exposures 15s@300g, UV/IR Cut Filter. Darks subtracted, no flats. Dithered and recentered in SharpCap. No guiding. |
| Description | At magnitude 10.3 and 1.8x1.3 arc minutes this is a challenging galaxy to observe with a small telescope. Overall the galaxy is circular, but extremely dim and the disc appears as background dust in both my capture and Arp's. Presumably, if you exclude the center bar, two of the three arms include the long, circular arm across the top and the nearly vertical descending bar at the right. The third arm is a bit more ambiguous, but presumably is the short descending bar to the left. |
