Strange, blue, circular, faint and extremely diffuse object

Unsure of what this object might be but considering I see it in almost every optical survey the sky viewer has, I know it’s real!

Could be a satellite galaxy of that spiral? Like our Magellanic clouds.

Oh no, absolutely possible! Just given it’s characteristics I’ve never seen such an almost perfectly round blue and extremely faint satellite like that before :sob: it’s very unique~
