Fourcade-Figuero Object.
I took a cheeky hour of luminance on this in between cloud bands on Tuesday, and was pleasantly surprised to see anything at all from Perth light pollution central. So last night I did a 6 hour run of LRGB. From the look of the subs some high clouds came through around midnight, but generally it worked out pretty well.
Discovered in 1970 in Chile, this is a streak of stars that has been ejected from NGC5128. The interaction that caused this happened 500 million years ago, and although the galaxy is only 13 million light years away, this galactic 'sneeze' has already crossed a surprising distance in the night sky - about 3 degrees. I've seen this object through my 25" and it was very faint, but detectable. I'm not sure if the lumpiness in the background is light pollution gradients or galactic cirrus.
The other blob at about 10 o'clock is ESO270-18 (the FFO is 270-17) and I can't find a single reference via Aladin on it, not even a redshift measurement, but the paper I found on the F-FO suggests it might be associated with the same event.
