Possible voorwerp

I don’t think its a voorwerp. It would be unusual for one to completely envelop a galaxy.

There also seem to be a lot of objects in that area with a blue tinge around them, so it may be something to do with image processing

This is not a #voorwerp. The blue Haze is everywhere in the image.

If you click on the “Single exposures” link,

you can see that one of the ‘g’ band images (= blue) – the second one down the list – is really blurry, which I think is what is giving all the objects that bluish halo.
