| Image Details | Up is 0.8 degrees E of N. Transparency: Fair. Seeing: Fair. Total integration time was 38m 40s. Exposures 20s@225g, No Filter. Dithered and recentered in SharpCap. No guiding. |
| Description | Another case where my monochrome CMOS camera is capable of capturing a deeper image than Arp's 200" using Emulsion D (the "standard" emulsion). "Very faint diffuse connection from both ends of N spiral to S spiral" aren't so faint in my capture, likely the result of longer wavelength emissions through near-IR. Appearance of fission? Arp abhorred what he called "merger mania" and rarely interpreted interacting galaxies as merging. Still, it appears more likely a merger in process than "fission". Captured on a mediocre evening, cut short due to worsening transparency. My 169th Arp capture, 50% of the Atlas' total. |
