    Yes, the colour isn't correct for an ordinary spiral. It shoud have a yellow or yellow-orange nucleus at that distance. This one looks orange-red. My thoughts:

    1. red spiral, gas-poor galaxy as discovered in Galaxy Zoo.
    2. red elliptical that has recently undergone a merger, so has #tidal_trail around it.
    3. overlap of a spiral with an elliptical shining through, not sure if that can happen.
