What's the purple on the underside?

    Is this just a misregistration or similar artifact? Or does the purple indicate something strange? In any case, the nucleus (or is it the bulge?) seems very distinct and bright, an #AGN perhaps?

    Purple is red+blue, so for it to be a mis-registration the green would be shifted with respect to the red and blue. I'd thus expect to see an extra bit of green opposite the extra bit of purple. Now that I've said that I can sort of convince myself I see it, but I'm not sure. None of the other objects nearby look mis-registered to me. Maybe this is real -- and I agree the nuclear region may be a compact bulge or an #AGN. If it's an AGN and the purple bit is real...

    (Has anyone started a collection of possible #voorwerp objects?)
