    #compact everything else is probably #artefact of large bright triple due E, seen clearly in both FIRST and NVSS

    Here's a zoomed-our FIRST image:

    While the linear streaks and 'compact blobs in a line' are likely artifacts (or mostly so), there are also some faint, diffuse clouds in the FIRST image. Are they artifacts too?

    Based on the images from both FIRST and NVSS, I would say the streaks visible are artifacts, but the 3 triangular blobs are real, as is the bright object on the line, but probably not quite as pronounced if the streak wasn't there.

    The visual sources for the various objects are:

    I'll add NVSS, and do some zoom-ins, later.

    Boilerplate: SDSS image per http://skyservice.pha.jhu.edu/DR10/ImgCutout/getjpeg.aspx, FIRST contours derived from FITS file produced using SkyView with Python code described in this RGZ Talk thread. Image center per the ARG image (left; J2000).
