Invisible tidal debris?

There seems to be tidal debris in the direction of the lower right star visible in DSS and DSS2, how is it possible DECaLS does not make this visible?

Check in Aladin Lite: http://aladin.u-strasbg.fr/AladinLite/?target=11%2028%2044.20000000-00%2017%2030.5000000&fov=0.03&survey=P%2FDSS2%2Fred

We only have one (of three, hopefully) exposures in g,r in that region, so we will be getting more depth in future data releases…

After checking / rechecking it is likely an optical artifact caused by a combination of two foreground stars in DSS, making it look curved instead of straight :confused:

Beginner’s mistake / fooled by artifacts…

Thanks,
