About this field

The nearest large spiral. Roman's field of view is wide enough to capture Andromeda's disk and halo in a handful of pointings, resolving individual stars across the whole galaxy.

The image above is procedurally generated. Source positions, colours and crowding are derived from the field's galactic latitude and character and from the band's pivot wavelength, and every exposure of a field draws the same sky so dithers line up — but none of it is data from the telescope.
