| Description | This target was captured on a dark night, with only so-so seeing. I was hoping to capture the target with both quasars visible. In the event, my captures only hint at them (In fairness, Arp's original only hinted at them).. This galaxy is one which Arp chose to present in a 2004 documentary. There he discusses the issues discovered by two young, Spanish astronomers who observed the target in 2001 and whose final results were published in a respected, European, peer-reviewed journal in 2004. The 2001 observations showed the two quasars located in the filament connecting the two galaxies. I find it highly unlikely these could all be accidents. The documentary included Margaret and Geoffrey Burbidge supporting Arp, which counts for a lot in my book as they are extremely credible. |
