After dismally managing to plough my own 14inch scope into the observatory wall on this target (dew shield didn't clear the wall), I managed to set up my 130mm triplet on a separate pier in my garden and caught some images of 2019y4 before it descended too low and disappeared into next door's shrubbery.   Will take a while to process anything fit to post but looking like two separate main areas and a fanning out of material behind it.
