Image DetailsUp is 109.8 degrees E of N. Total integration time was 45m 15s. Exposures 15s@300g, UV/IR Cut Filter. Darks subtracted, no flats. Dithered and recentered in SharpCap. No guiding.
DescriptionArp 182 displays two faint filaments extending from what otherwise appears to be an intact spiral galaxy: The first is an extremely subtle extension more or less down, slightly skewed in the direction of NGC 7675. I'm frankly not sure it's visible in my image (and perhaps I think I see it due to confirmation bias) and is barely visible in Arp's published image. Slightly more obvious is semi-circular filament extending up and to the left, which I can reliably perceive in my 45m capture. It leaves me wondering about the relative motion of two small galaxies: one almost directly to the left the other straight up. Interestingly, Arp didn't include these in the atlas photo of Arp 182. Perhaps they are outside the FOV of his telescope? They do seem relevant to understanding the filament's shape and direction.
