For the last 134 years people have photographed the andromeda galaxy, but everyone up until now has missed this giant undiscovered nebula!

@sandorkruk to be fair that's a BIG patch of sky in that image. Like several full moons across.. and you need really deep and precise imaging to pull something so LSB out... so I don't find this too surprising.
@sandorkruk (cool though to this that it was hiding there all this time!).
@karenlmasters @sandorkruk i poked very briefly at the rnaas and could not satisfy myself that this was not Galactic. Do we know this is not Galactic? It looks a lot like the magnetized structures we have been studying in the MW for about a decade.
@jegpeek @karenlmasters @sandorkruk Agree. But such a cool mystery!
@rdrimmel @karenlmasters @sandorkruk has someone looked in the HI?
@rdrimmel @karenlmasters @sandorkruk *cough* @HIprocessor *cough*
@HIprocessor @rdrimmel @karenlmasters @sandorkruk seems like astrometry.net might give you a reasonable fits header?
@jegpeek @rdrimmel @karenlmasters @sandorkruk
If you upload to astrometry.net it gets a CC license, which I cannot do, as I do not own the image.
@jegpeek @rdrimmel @karenlmasters @sandorkruk Actually I did, but it's hard to say. I don't have a proper fits file with Bray's image and there is lots of filamentary stuff in this area.
